0:00So you want to learn how to make
0:01stylized rocks. Well, in this video,
0:03we'll be going over how to model and
0:05texture them in Blender and Substance
0:06Painter. So let's begin.
0:08Okay, to start, just add in a cube. If
0:11you want to get these edge highlights,
0:12just go over here, select cavity, go
0:15into both, and increase your ridge and
0:16valley up to the max. Next, what we're
0:19going to do is select all these faces,
0:22go up to mesh, select bisect. You should
0:24also add a shortcut here. I'll just set
0:26that to four, then bisect it.
0:30And then just cut a little bit off. And
0:32then let's just do this over and over
0:34again from multiple different points of
0:36views, just cutting off little bits at a
0:38time, cutting off little bits of rock
0:41until you get something that looks
0:43decent. You can also reshape this while
0:46you go,
0:47re-angle it and such. Also, when you're
0:50bisecting, make sure that you have fill
0:55and clear outer or clear inner selected.
1:05>> [music]
1:06>> Okay, once you have your basic shape
1:08finished, just duplicate this and move
1:11it to the side. Then you can either just
1:14keep this or you can go into sculpting.
1:16And if you're going to go into
1:17sculpting, what I usually do is just add
1:20a remesh, then increase this by quite a
1:23lot. Now, this will lag out your
1:25computer a lot, so don't go too high
1:27with this. You can always go into
1:29statistics and see what your triangles
1:31are at. You can increase this even more.
1:33After this, I'm going to go into
1:35sculpting. I have a whole series of
1:37brushes that I use that I will link in
1:39the description. They are free, so you
1:41know, hopefully you can afford that. And
1:43yeah, I'm just going to sculpt a little
1:45bit. Make sure you apply the remesh
1:46modifier.
2:06>> Now, there's really no trick to
2:08sculpting the edges. I just mainly just
2:10do random strokes along the edges cuz I
2:12think that looks pretty nice.
2:25Okay, once all the edges are done,
2:28I typically do is go in and add some of
2:31these. Just add some of these along the
2:34creases. Get some good detail in there.
2:43Just add some variation to where it is
2:45and such.
2:51I'd say that looks pretty good. If
2:53anything, that's a little too many
2:54scratches.
2:55>> [music]
2:55>> Next, I'm going to add some of these
2:57little light masks that helps make
2:59texture look a little bit better. Now,
3:01you don't have to do this if you want to
3:03just a flat looking rock. I just like
3:05how it looks, so.
3:10>> [music]
3:12>> Now, since this is 2 million triangles,
3:14that's a little too much for a game
3:16asset. So, we're going to bake all this
3:17detail into this lower poly one, so it's
3:19only [music] 68 triangles. So, add the
3:22world origin there and then snap that
3:24there. Select the high poly one, go to
3:27export FBX, call this stylized rock
3:30[music]
3:30high, selected objects, then you can go
3:33ahead and hide that. Now, for the lower
3:34poly one, you want to select everything,
3:37select all edges,
3:39mark seam, press U, unwrap angle based,
3:43increase this margin a little bit, and
3:45then check out your UVs. That all looks
3:48good to me. Then, just
3:50export FBX, stylized rock low, and then
3:54export. Now, boot up Substance Painter,
3:58click on new, select your low poly rock,
4:03and then press okay. Then go into your
4:05baking settings, then go into high
4:07definition meshes, click this right
4:10here, and select your high poly mesh.
4:13Then if you see these little red bits,
4:15increase the max frontal distance until
4:17they go away. Also, increase your
4:19anti-aliasing to 16x. Make sure
4:22everything looks good, then bake
4:23selected textures. Now you have all this
4:26information. Looks pretty good. Now just
4:29add a fill layer and set the roughness
4:31to 0.8 or something so there's no shine
4:34and reflections on it. You can also just
4:36disable all of those. Now, there are two
4:38ways you can go about this. You can
4:40either paint on some texture yourself,
4:42or you can add in fill layers and put in
4:46generators to non-destructively create
4:49your texture. And you can also save that
4:51texture and use it across multiple
4:53assets, which will increase your
4:55workflow significantly. And that's the
4:57way I'm going to be teaching it. Now,
4:58with any good texture, I'm going to
5:00start with a base color. So, I want this
5:02rock to be just a dark gray. Can add a
5:06little tint of blue in there. Just
5:08something like that will do. Make sure
5:10to add in a folder and organize this.
5:12Going to name this base.
5:15Drag that in there. Now, we can start
5:17with some color variation. I'm going to
5:20duplicate this,
5:22make it a little more blue. Going to go
5:24[music] into add a black mask, add fill,
5:27then search up clouds.
5:30And then this is what's going to be
5:32creating the mask, so it's not uniform
5:35all around it. You can also tweak this
5:38by increasing the balance. I would
5:40recommend going to mask you for this.
5:42See that there.
5:44Increase the contrast. All of the black
5:46bits are where the blue's going to be.
5:48I'd say something like that works. Let's
5:50go into the material view. It's very
5:52subtle, but you can still see it. Now,
5:54I'm going to duplicate this and instead
5:56make this one a little bit green. Then
5:58you can just copy mask
6:02and then paste into mask. Then you can
6:05see that there. Decrease the balance a
6:07little bit more. Play with these values
6:09a little bit. Also, you want to set this
6:11clouds texture to a different seed.
6:18Next, we're going to work on the
6:20edgewear. So, [music] add in a new
6:22folder. Name this edges. Add in another
6:26base color. You can do alt click to only
6:29work on the color. Make this a little
6:31more gray. Then go into black mask. Add
6:35generator.
6:36Search up curvature, then boom, here
6:38[music] it is. You can decrease this
6:39balance a bit. You can also increase
6:41these things. Say something like that's
6:44probably probably good. Just something
6:47like that. Then we can go into Make sure
6:50this is set to linear dodge. Then add in
6:54a filter. Add in a blur slope. This will
6:57add a nice little painterly effect. I
7:00usually set this to about 10, then play
7:02with the intensity [music] a little bit.
7:03Then I add in a blur. So, just add a
7:06filter, blur. Play around [music] with
7:08the intensity a little bit. So, I want
7:10it to be very slightly blurred. Then
7:12ultimately
7:14decrease this a little bit like there.
7:16Always decrease this a little bit. Now,
7:19we can duplicate this. Also name this
7:22high curve. This will be the medium
7:24curve. Set this to 100% so we can see it
7:27a little better. Then you can delete
7:30that blur node. Increase the balance a
7:31bit. We want to decrease this huge and
7:34decrease this one quite a bit.
7:36Increase the large though. Go like
7:39there. Like that.
7:42You can decrease the capacity again.
7:44Then duplicate this, make this one just
7:48the sharp curve. Now for the sharp
7:50curve, you can remove that blur slope,
7:52>> [music]
7:52>> increase the global bounce, increase the
7:54opacity, then you want to decrease all
7:57of these completely.
7:59You only want the sharp and fine ones.
8:02Create a nice little edge effect. Okay,
8:05now we have all of these. You can set
8:07the folder to linear dodge, then
8:10decrease the opacity, blend it a little
8:12nicer. I would say that looks pretty
8:14decent. Also, you can increase color
8:17this, bring out those edges a little bit
8:19better. Next [music]
8:21is the environment baking. Now this will
8:25bring your texture to life. So just make
8:28a new folder, call it baking
8:30environment. We will start with a light,
8:32so I've just alt click the color, add in
8:35a black mask, add in a generator, set
8:37the generator to light, and go to base
8:40color.
8:41See it a little bit better. We want it
8:43to be casting down. We want light to be
8:45casting [music] down, so we can create
8:47cool effects. So just adjust the
8:48horizontal and vertical angle, so it's
8:50about [music] even on all sides. Then we
8:53can adjust these things, make it a
8:56little more subtle
8:58and such. Now it's always important to
9:00have some type of blending mode instead
9:02of normal, so all that textures combine
9:05together in a more realistic and a clean
9:06way. Then you can just darken that a
9:08little bit, decrease the opacity a lot,
9:11so like that so now the parts are
9:13lighter at the top. Then you can just
9:16name this to light. You can just [music]
9:18duplicate this, bring drag it down, name
9:20this shadow, set this to a dark color,
9:23want a little bit blue. Right there
9:25works. Then go into the light generator
9:27and just hit invert. Can play around
9:29with the settings a little bit. Go like
9:31that.
9:32Honestly increase that a little bit.
9:34Also, [music]
9:35set this to overlay and set this one to
9:38screen. [music] There you go. So, little
9:41bit of shading. If it's always too much,
9:43you can just
9:44go up here and decrease it like that.
9:47Just do it very slightly. That's with
9:48it. That's without. You can decide it
9:51whether or not you like it or not, and
9:52you can always just disable [music]
9:53that. Next, we're going to add in some
9:55ambient occlusion. Just going to name
9:57this folder other cuz it's going to hold
9:59our moss, our dirt, [music] and our
10:01ambient occlusion, just random things.
10:03So, add in a fill layer. Set this to a
10:06dark color. Make sure it's only the
10:07color. Add in a black mask with
10:10generator and add in a ambient
10:12occlusion. Make sure it's set to [music]
10:14invert. This will just highlight the
10:16shadows. If your model like bends into
10:18itself,
10:20then it will highlight the shadows
10:22there. But, since [music] mine doesn't
10:23do that, it doesn't really matter too
10:25much. Make sure this is set to soft
10:28light this time. Just a random blending
10:30mode. You can decrease the opacity as
10:32much as you want. That just makes the
10:33shadows darker. I'd say that's a little
10:35too much. Next is the dirt layer. So,
10:38what I'm going to do is add in another
10:40fill layer. You can name this to a
10:41little dirt. Make sure it's only color.
10:44I'll set this to a nice nice darkish
10:46green. Something like that will do. Add
10:50in a black mask. [music]
10:52Add in a generator.
10:53Put in a dirt generator. Now, this dirt
10:56generator will just add in some nice
10:59little nice variation. This [music] is a
11:02little bit too much. So, I'm just going
11:04to decrease the dirt level quite a bit.
11:07To add some little smudges everywhere.
11:09Decrease the contrast. Decrease the
11:11opacity of the mask. Next, add in
11:13another fill layer. Make sure it's only
11:15color again. This one will be the moss.
11:18So, set it to a nice earthy light green.
11:22And this one will take quite a bit of
11:24generators. So, first we're going to
11:26start with the 3D linear gradient. Just
11:30want it to be top down. Something like
11:32that will do. Then add in another
11:35generator. This one will be light. Set
11:38this to multiply as well, so it
11:40multiplies with a 3D gradient. Make sure
11:42that hits the top of it. You can always
11:45go into mask and see how what it's
11:47looking like.
11:49Just align this so it's hitting the top
11:51bits. Also go like that so it fades a
11:54little bit better. Something like that
11:56will do. You can press M to go back to
11:58material mode. Something like that works
12:00well enough. That way it accentuates the
12:02top facing bits.
12:03>> [music]
12:03>> Next you're going to be adding in a fill
12:05layer. Set this to multiply.
12:07Make sure it's a clouds texture.
12:10Then just adjust the balance of the
12:13clouds for how much moss you want.
12:15Increase the contrast a little bit. Set
12:17the seed as well. Something [music] like
12:19that works a little bit better. Then you
12:21can also increase or decrease [music]
12:23the opacity of these depending on how
12:26you want it to look. Then add in another
12:29generator. This will be the last one.
12:31This will be curvature. Make sure it's
12:34set to multiply. Now we're doing this to
12:36make sure the edges have less moss as if
12:39they've been worn off or something like
12:41that. I don't know. So just set inverse
12:44and adjust the global balance. Make sure
12:46to remove all of these ones. Add a
12:48little bit of large. Add a little bit of
12:50medium. Add a little bit of soft. But
12:52mainly you just want it to be the
12:53points. [music]
12:54You can increase or decrease the balance
12:56accordingly. I personally set this mask
12:59to very transparent. There you go. And
13:02this is with and without the moss.
13:05So you can decide which look you're
13:07going for. And that's really it on how
13:10to texture it. You can always go in and
13:13hand paint some things. You know, add in
13:15some custom variation. But I'm not very
13:18artistic, so I don't typically do that.
13:20But what I will do is just add in
13:23another fill layer. Set that to that.
13:26Make this more yellowy green. Something
13:29like that will work. Add in a black
13:31mask. Add in a fill layer. Look for
13:34something good. What does that look
13:35like?
13:38Go like that or something.
13:47Okay, so if you don't have Substance
13:49Painter, you can texture it in Blender
13:51by doing this. You see you select your
13:53object, go to texture painting, go up to
13:55texture slots, add a new base color, set
13:58this color to what you want the rock to
14:01look like. So I want it to be a dark
14:02slightly bluish color. Say something
14:04like that works. You can uncheck the
14:06alpha. Just add it. Then you can You can
14:09go up to here.
14:11Select flat and then texture. That way
14:13there's no shading that's affecting it.
14:15And then you can just
14:17texture paint directly onto the model.
14:19Make sure you have good UVs, too.
14:21[music] So what I'm going to do is add
14:23in a new brush. I'll just select this
14:26one. I found this brush just by
14:27searching up spray brush in Google. So
14:30make sure this is set to view plane and
14:32then select random. You can also press
14:34shift X to select the color directly
14:37underneath, as you can see there. And
14:39you can [music] change it, do whatever
14:41you want. You can press F to adjust the
14:43brush size. You can do shift F to adjust
14:47the brush stroke. [music]
14:48So I'm just going to be painting over it
14:51a little bit. Add in some custom color
14:53variation.
14:56Now, I don't typically texture in
14:59Blender, so [music]
15:00the end result might not look amazing.
15:02I'm still just going to try it, though.
15:08Then I'm going to add in another brush.
15:10This one will just be a simple little
15:12square brush with a little bit of
15:14gradient. Okay, so for the edges, what
15:17you can do is enable the cavity, then
15:20just paint over.
15:32Then I'm going to add in a little bit of
15:34lighter color, decrease the stroke size.
15:55Okay.
15:56Then that's the texture done. Since I
15:58don't typically use Blender, it doesn't
16:00look the greatest or anything, but you
16:02know, it is what it is. Let me compare
16:04it with the Substance Painter one. So,
16:06obviously they are pretty different
16:08looking. The good thing about the
16:09Blender one is that it's free, but the
16:11downsides are that it's not procedural.
16:13So, if you need to make a change, you
16:15need to alter all of it. With the
16:16Substance Painter one, you can easily
16:18just go and change, like remove the
16:19moss, add some more edge wear, and all
16:21that within like one click. If this
