How To Make Roblox UGC Hair [Blender Step-By-Step Tutorial] — Transcript
Full transcript
- 0:00So, in this video, I'm going to show you
- 0:02how to make UGC hair in Blender. We'll
- 0:05start by importing the Roblox dummy. So,
- 0:07we have some guide for shaping the hair.
- 0:10So, let's go to the Roblox Studio. Just
- 0:13go into the this upper panel, go to
- 0:15avatar, go to rig builder, select R six,
- 0:20and select block avatar. Then you will
- 0:22see avatar appears in the explorer tab.
- 0:25Go into the rig, right click on the rig,
- 0:27and save and export. export selection
- 0:31and then you will just save it somewhere
- 0:32on the desktop and name it I don't know
- 0:35dummy. Uh then we can open the blender.
- 0:37When you will open the blender you will
- 0:39see this scene. So we're going to just
- 0:42delete all of it. So press press A and
- 0:44delete. Then we want to import the the
- 0:47dummy. So let's just go to the file
- 0:49import obj and just select the OBJ file
- 0:53of a dummy and select and then go to the
- 0:56front view. I would just use the
- 0:58shortcuts but you can also go here to
- 1:00the view. You can just select views from
- 1:02here. Then select our character go to go
- 1:05to object sect origin and select origin
- 1:08to geometry. And then what we want to do
- 1:12is basically just just snap selection to
- 1:15the cursor. So it's so our dummy is in
- 1:18in the center. I will just be make a
- 1:20collection and name it dummy. We're
- 1:23going to move this model to the dummy
- 1:26collection. So we can everything is more
- 1:29is uh much more organized. So I can just
- 1:32I press shift A go to mesh and select
- 1:35circle under this panel. Select vertices
- 1:38and type three. Press enter. And you
- 1:40will see if you go to the top view we
- 1:43have this triangle. I will go to edit
- 1:46mode. Select this vert G and Y. And I
- 1:50will just
- 1:52slightly move a bit down. So it's so our
- 1:56hair strand will be a little bit
- 1:58thinner. So with that I can go here and
- 2:01name it hair shape.
- 2:06Hair shape go under object select
- 2:09convert and convert it to curve. We can
- 2:12hide this one. So now we will make air.
- 2:16You will press shift A. Go to curve
- 2:19under the and select pet. I will rotate
- 2:21this pad 90° by typing R and 90. Now you
- 2:27select the path, go to curve properties
- 2:31under the GI geometry
- 2:34under the object and select air shape.
- 2:36You will see that our shape is rotated
- 2:39to the wrong way. So go to edit mode,
- 2:42press A to select all, press CtrlT, 90.
- 2:46We will right click on it and shade it
- 2:48flat. And you can see this will be our
- 2:51hair. I will basically tell you the main
- 2:53controls. You can select whatever vert
- 2:56you want in edit mode and press G. And
- 2:59you can see you will you can move it.
- 3:01You can move this one, this one, this
- 3:03one, what whatever vert you want. And we
- 3:06will also use CtrlT to rotate the verts
- 3:11to basically tilt the verts. And we will
- 3:14use alt s alt s to basically shrink the
- 3:19hair. So with that we will make a hair.
- 3:21I will select this vert. Press alt s and
- 3:24zero. shrink it to the zero. And we will
- 3:27select this one. This vert. And we will
- 3:30do the same. And I can see this too
- 3:32thick. I will select all. And just
- 3:35shrink it a little bit. And this will be
- 3:38our hair. So now we'll start with
- 3:40modeling the hair.
- 3:42uh we will start modeling from the back
- 3:44of the hat and work way to the front.
- 3:46And after the main shape of the hair is
- 3:48done, we're going to add some details.
- 3:51So what we want to do is unhide the
- 3:54dummy and basically as you can see our
- 3:57hair is too long and it's rotated the
- 4:01wrong way. So I will select this one,
- 4:03shrink it a little bit, move move it up
- 4:07and with in edit mode I will basically
- 4:11Ctrl T 90
- 4:16once more and you can see it's basically
- 4:19here in the back of the head. I will
- 4:21just use G
- 4:26to
- 4:28basically make a shape that I want.
- 4:36I think it's a little bit too thick.
- 4:40We I will add thickness with alt s on
- 4:42the vert and basically just shrink it a
- 4:44little bit. I will also add thickness
- 4:48here
- 4:49[Music]
- 4:53and see it's a bit a bit too thick.
- 5:00[Music]
- 5:07Now I will duplicate this hair by shift
- 5:11D and I will go to the edit mode and
- 5:14just I will just move it a little bit.
- 5:17So this will be our second hair. It's a
- 5:20little bit too thick.
- 5:23[Music]
- 5:28As you can see from the top it's a
- 5:30little bit too further from the this
- 5:32main shape from this hair strand. So I
- 5:36will go to side view, select these ones
- 5:40and just put it a little bit
- 5:45a little bit further.
- 5:58I want to mirror this hair to the other
- 6:01side. We will do this like that. So
- 6:03press A. Go to empty, select plane axis.
- 6:08We can hide the empty. Select this pair.
- 6:12Go to modifiers. Add modifier and select
- 6:15mirror modifier. And under the mirror
- 6:18object, select select the empty. And you
- 6:20can see we added the left side. And
- 6:23basically when we are going to control
- 6:25this part, the other half will behave
- 6:27like that too. So I'm just basically
- 6:29here aligning these edges. So basically
- 6:34when we're going to merge all of these
- 6:36it will be a much it will be much
- 6:38easier. So the back is I think it's
- 6:41okay. Now we're going to add a pet
- 6:45because I will do the different
- 6:48uh the different hair.
- 6:54[Music]
- 7:00Go to curve properties under object
- 7:04select hair shape shade it flat and we
- 7:07can see it's rotated to the wrong side.
- 7:09Uh we will go to edit mode press a ctrl
- 7:14t and press 90. We need to rotate it in
- 7:19our way. Press a alt s and shrink it a
- 7:22little bit. This for this hair, this
- 7:25curve will be shrink to the zero. But
- 7:28this one will be open like that but a
- 7:32little bit
- 7:34less
- 7:37cuz we want to make like this one. Let's
- 7:41see.
- 7:43Go like that.
- 7:50[Music]
- 8:01We will do the same as we did before
- 8:03with the mirror modifier. So just select
- 8:06this one. Go to modifiers and select
- 8:09mirror modifier. Press mirror object and
- 8:12select empty. And you will see there is
- 8:15another one. We'll select clipping.
- 8:32[Music]
- 8:45[Music]
- 8:55[Music]
- 8:57Heat. Hey, Heat.
- 9:00[Music]
- 9:06[Music]
- 9:18So if we if we have holes like that,
- 9:20don't worry because we will we will
- 9:23merge them together anyway. So it
- 9:25doesn't matter.
- 9:27[Music]
- 9:30But we can always check how is how does
- 9:32it look when the dummy is selected. So
- 9:35we will add one more hair here and then
- 9:38we will add uh basically the front part
- 9:41of the hair and then bangs. I will
- 9:44duplicate this one. So by selecting this
- 9:47and shift D I will move it just a little
- 9:50bit further.
- 9:52I will shrink it a little bit. Select
- 9:55this birds and tilt it a little bit.
- 10:00So it's open.
- 10:02[Music]
- 10:14[Music]
- 10:25[Music]
- 10:37So with that set, we're going to add
- 10:39pet.
- 10:41Rotate it 90°. Select. I would just
- 10:45shrink it a little bit. Go to front view
- 10:49and try to align
- 10:52that flow of this hair.
- 11:00So, let's just go to curve properties,
- 11:03go to geometry and under bevel, select
- 11:06object shape. Um, we need to shade it
- 11:10flat and rotate it. Just go select A
- 11:13with alt S. Shrink it a little bit.
- 11:18And I want this vert to scale to zero.
- 11:33[Music]
- 11:44[Music]
- 11:56[Music]
- 11:57So now I will start the banks. I will
- 12:00make error as we did before.
- 12:08For the banks, I will only shrink the
- 12:11bottom vert.
- 12:13And I will shrink it a little bit and
- 12:16make it.
- 12:19I will bring it to the front.
- 12:29We must align the edges.
- 12:39Something like that. And we will mirror
- 12:42this part. And now we will start with
- 12:44the inner part.
- 12:50[Music]
- 12:58[Music]
- 13:07[Music]
- 13:16With that we can and use proportional
- 13:19editing too to make it more like flowy
- 13:21more realistic. So for that we're going
- 13:24to this upper panel. Select this one and
- 13:27basically I will just smooth. I will
- 13:29just use this smooth one and select on
- 13:32it only. You can see I can grab it and
- 13:34with mouse wheel up and down I can
- 13:37control the influence of it.
- 13:40[Music]
- 13:53[Music]
- 13:55Move this part a little bit in. This one
- 13:57a little bit out. Make that O shape.
- 14:08[Music]
- 14:16You can make it easier and just just
- 14:19select this part and press shift D to
- 14:21duplicate it. And I can just move it out
- 14:24of the way. And we have another one
- 14:26without repeating the creating path and
- 14:29all of that. So, it's much much faster
- 14:31and much easier.
- 14:38[Music]
- 14:49[Music]
- 15:23[Music]
- 15:34[Music]
- 15:37So, we've just ended with the base. So,
- 15:40I'm going to start with some with adding
- 15:42some details. So after that we'll start
- 15:44with margin.
- 15:46[Music]
- 15:57[Music]
- 16:08[Music]
- 16:19[Music]
- 16:58[Music]
- 17:11[Music]
- 17:21[Music]
- 17:28So now we need to basically select the
- 17:31hair and lower resolution of the hair.
- 17:34So for that we're going to go curve
- 17:37properties and we will just in this tab
- 17:41where there is 12 we're going to type
- 17:42six and we will repeat this step with
- 17:46all the hairs.
- 17:48[Music]
- 18:06[Music]
- 18:08After we finish with lowering
- 18:09resolution, we can start merging the
- 18:12hairs. And for that, we need to we need
- 18:14to basically turn off the mirror
- 18:16modifier for all of the hairs.
- 18:20I I will only disable this one first and
- 18:22I will do the others later. I will hide
- 18:25the details and I will start with this
- 18:27one. Basically we what we want to do is
- 18:30just to align we need to align the edges
- 18:33more because they are not aligned good.
- 18:35I think that's good. So now we want to
- 18:38go to we want to select this hair go to
- 18:41object and select convert and converted
- 18:44to mesh. And we want to do this same
- 18:46with this hair. Now when both of these
- 18:49hairs are converted to mesh we want to
- 18:51select both of them press right click
- 18:54and join. Now we can go to edit mode and
- 18:56basically we go a clue press M and merge
- 18:59it at center. So we can repeat that with
- 19:02all of the hair.
- 19:06By merging all of these uh verts we will
- 19:09make that hair has a lot less tries and
- 19:13there won't be any holes in the mesh. So
- 19:15it will be perfect for Roblox Studio. If
- 19:18we have vert like that can just press
- 19:20CtrlR we can basically add an edge loop
- 19:24can just select both of these verts and
- 19:26merge it at center. We can do the same
- 19:29here and we successfully merge this
- 19:32hair. We want to repeat this process
- 19:34with all of the hair.
- 19:36[Music]
- 19:48[Music]
- 19:59[Music]
- 20:10[Music]
- 20:22[Music]
- 20:27After we merge all of this part, we can
- 20:29go to mirror modifier and apply it. We
- 20:33can basically we can also select this
- 20:37clipping and go to edit mode and slide
- 20:40all of these birds to the center.
- 20:46So the mesh is even cleaner. And
- 20:48basically this part is done. We can hide
- 20:52this part and this one. Now we have this
- 20:55part to merge. It's the same process as
- 20:57before. We need to hide the mirror
- 21:00modifier. Select this object and convert
- 21:03it to mesh. We do the same with this
- 21:06part.
- 21:10And so we can see I can only work on one
- 21:13half and the other half is doing the
- 21:15same. So it's much faster. For now,
- 21:18we're going to leave this part and we're
- 21:20just going to focus on this one. So for
- 21:22that one, we need to merge all of this
- 21:26part so there won't be any holes on it.
- 21:34[Music]
- 21:45[Music]
- 21:48Uh go to object convert it to mesh. And
- 21:52now I will join these parts. Right click
- 21:55and select join. And I can merge this by
- 21:59pressing M and select at the center
- 22:06[Music]
- 22:11with this vert with this edges which
- 22:15basically don't have any connecting any
- 22:17verts that I can connect. I will I can
- 22:20just dissolve this edge. So basically go
- 22:22to edge selection, hold alt, press on
- 22:25the edge and click ctrl and x and you
- 22:28can see the edge is dissolved and repeat
- 22:30this with all of these edges here.
- 22:34[Music]
- 22:35That's it. Now I can apply mirror
- 22:37modifier.
- 22:39Now I can focus on this part this and
- 22:41this. Go to object convert it to mesh
- 22:45and now press. We can also use the
- 22:48shortcut Ctrl J to join them. And now I
- 22:51can merge them.
- 23:04[Music]
- 23:15[Music]
- 23:38Same with this one. If we want to
- 23:40disable the mirror modifier to just
- 23:42focus on one part and then after we
- 23:44merge it, we can uh mirror it then. So
- 23:48it's much easier. So I would just adjust
- 23:51a little a little better this edges so I
- 23:53can it will be a lot more easier for
- 23:56merging. I will select this and this. I
- 23:59will go under object and under convert I
- 24:02will convert it to mesh. And I will also
- 24:05press Ctrl J to join them. Go to uplute
- 24:10and to edit mode and I will just start
- 24:12merging this at center by clicking M and
- 24:16at center. This one is a little bit
- 24:18trickier.
- 24:23I think this will this will be okay. And
- 24:26now we can apply mirror modifier. If we
- 24:29want to publish this hair on the Roblox
- 24:31marketplace and make some money and make
- 24:34some Robuxes, we need to lower our
- 24:37triangle count. So, it must be under
- 24:394,000 tries. I can show you how you can
- 24:42see this how much you have. So,
- 24:44basically, you will go up here in
- 24:46overlays and you will select statistic.
- 24:49And now you can see in the left corner
- 24:52we have 4,56
- 24:54tries. So, this is too much. We need to
- 24:57go, we need to lower it under the 4,000
- 25:00tries. So, I will show you how to do
- 25:02that. First of all, we will select this
- 25:04big part and we will go to edit mode and
- 25:07to edge selection. We can select it
- 25:09here. And as you can see, there is a lot
- 25:12of this edge loops. So, we can dissolve.
- 25:15The better edges to dissolve are the
- 25:18ones that are on the flat surface like
- 25:20like that. So, by clicking alt and
- 25:22selecting them, you're selecting the
- 25:24whole edge. Then you're going to press
- 25:26Ctrl and X and you will see the edges
- 25:29deleted. I will I will delete this edge.
- 25:31I will delete this edge. We also don't
- 25:34need this one and this one. This and
- 25:36this. We can go into the side view. We
- 25:39don't need this one.
- 25:44So as you can see in this in this part
- 25:46there is too many loops. We can dissolve
- 25:50many of those. So I can do this and this
- 25:53and this. I will do this with with other
- 25:56art.
- 26:01[Music]
- 26:13[Music]
- 26:35[Music]
- 26:48After we reach triangle count under four
- 26:514,000 tries, we can start merging all
- 26:55the part that we didn't convert it to
- 26:57mesh and basically join the whole mesh
- 27:01together.
- 27:09[Music]
- 27:12Um, now I can apply apply this uh mirror
- 27:15modifier so I can so I can basically
- 27:19merge the verts on the back of this hair
- 27:21strand. So,
- 27:24and apply it. Now I can convert this and
- 27:27convert this to mesh. Select this part
- 27:29and this part. Right mouse click and
- 27:31join. Now I can start merging the back.
- 27:45I will add edge loop here. So I can
- 27:47connect these birds and this one. Now I
- 27:50have repeat with this one.
- 27:57This part is not connected to this one.
- 27:59So I need to join them together. Just go
- 28:01to mirror modifier and apply it. Select
- 28:05this part and this part and right click
- 28:07and join. Then we can start merging.
- 28:09[Music]
- 28:17[Music]
- 28:24I can also apply this
- 28:28[Music]
- 28:40[Music]
- 28:48And basically that's it. Now I can press
- 28:50Ctrl A and right click and join. And we
- 28:53have and with that we put all parts into
- 28:56one mesh. So it's united into one mesh.
- 28:58And as you can see, it's a little bit
- 29:01not smoothed out. It's a little bit
- 29:02flat. We want to smooth this hair up. So
- 29:06just right click on it and shape auto
- 29:08smooth. And as you can see, it's much
- 29:10more more smooth.
- 29:13So now after we finished the hair, we
- 29:16want to check a few things. So the first
- 29:18thing is to make sure that that the
- 29:21normals are pointed the right way. So we
- 29:24want to make we want to check that. So
- 29:27we do that by going here to view port
- 29:29overlays and just select the face
- 29:31orientation. As we can see the blue part
- 29:34is okay. That means that normals are
- 29:36pointed the right way. But the red means
- 29:38that they're not. So basically we need
- 29:40to flip them. We can do that by
- 29:43selecting the object going to edit mode
- 29:46press A and then just press shift and N.
- 29:48And we can see it flips. But this part
- 29:50is missing. So we need to hover over
- 29:53this part and press L and then shift and
- 29:56N. And here we want to recalculate
- 29:58normals and just check inside. And here
- 30:01we go. This is how we check the face
- 30:03orientation. And now you can basically
- 30:05turn off this this feature. So after we
- 30:08flipped our normals, we want to add some
- 30:11textures. We do that by going to this
- 30:14material preview. Just click on this
- 30:16icon. As you can see, we don't have any
- 30:19textures. So we will apply that. What
- 30:20you want to do is go here and just
- 30:25slide a new window. In this step, we
- 30:27will open shader editor. We you will go
- 30:29into this icon and just you will select
- 30:32shader editor and this window will pop
- 30:35out. You will press on this principlef
- 30:38and press ctrlt. Now in this image
- 30:41texture you will open your hair texture.
- 30:44I will choose one of my own.
- 30:47Let's say this one. But as you can see,
- 30:50our texture is not correct. It's flip on
- 30:53the right. So, we want to fix that. So,
- 30:56go to UV editor and under this icon,
- 31:00select our texture. Go to this tab,
- 31:02select our mesh, go to edit mode, select
- 31:06all, and just press R and rotate it like
- 31:1090°. As you can see, our UV texture is
- 31:14fixed.
