Full transcript

1. 0:00You have an unusual idea for a 3d model but no idea how to realize it?
2. 0:04I will show you how to play god
3. 0:06Today, we will merge a fish with a renoceros .. to sculpt a horrible, yet cute creature
4. 0:12and in doing so i will show you all the steps you need to get from your first idea to a finished 3d model.
5. 0:18Whether for a game, for animation, or a awesome 3d artwork.
6. 0:26Alright, let's start with a new project by selecting the General Template
7. 0:30And by pressing A to select all, then X, we can delete all objects
8. 0:35Let's find a reference image for our creature on google. I
9. 0:38will use the body of a rhino, because I have no idea what I will be sculpting, I just know that the creature should be massive.
10. 0:45You can find good references by typing your keyword and than front or side view. In this case "rhino side view"
11. 0:51Just grab whatever you want and download it.
12. 0:54Back in blender, go into front view and by pressing shift + a you can add a reference image.
13. 1:00Insert it and move it a bit up so that the feet match the x axis
14. 1:04And decrease the opacity to better see our mesh
15. 1:08We also have to move the image a little to the back so that it does not disturb us during modeling
16. 1:13So, go to side view and press G Y to move it back
17. 1:18Ok, time to create our first mesh
18. 1:21Press Shift A to add a cube
19. 1:24And we will add a subdivision modifier to increase the number of polygons on this cube
20. 1:29Increase the Subdivision Level by clicking on the arrow toooo ... 5
21. 1:34And apply the modifier
22. 1:36finally, let's get the mesh in position and start sculpting!
23. 1:41Sculpt mode can be overwhelming the first time, but let me give you a abstract overview .. i will go more into detail when we use certain tools
24. 1:49On the left side, we have all the brushes blender has to offer
25. 1:52On the top, there are some brush settings like the radius and the strength
26. 1:57And on the right side, there is a tab for all Brush and Tool settings
27. 2:01Sculpting can be broken down in 3 Major steps
28. 2:04First, the Blockout Phase.
29. 2:07In the blockout phase you will be working with a very low resolution mesh
30. 2:11The goal is to roughly form the shape of your model by either using sculpting brushes, or adding new meshes
31. 2:17In the Second phase, you will sculpt the final shape. Even some detail will be done here, but only the ones, that define the sillouette of your model.
32. 2:28Here is an example of a detail, that should be modelled
33. 2:32And one, that should NOT be modelled. This detail will be sculpted in the last phase and later baked into the normal map.
34. 2:39After the final shape has been sculpted, your model will be retopologized, in other words: You create a low poly mesh with the shape of your sculpted high poly mesh
35. 2:49And in the last phase, you will add the fine detail like creases, surface inperfections ... and so on
36. 2:56Now that you know how we're going to proceed, let's talk a little bit about some shortcuts and brushes we'll going to use in the first phase.
37. 3:03When you press F, you can increase or decrease the radius of your brush
38. 3:08Holding down CTRL changes the brush direction. So in case of the draw brush, it creates a cavity instead of raising it
39. 3:15And holding down the Shift key, you can smooth our your mesh. It's the same as using the smooth brush, the settings are thus taken over
40. 3:23As for the brushes, we will mostly use the ... draw brush ... draw sharp ... grab ... and snake hook
41. 3:33Ok, enough the theory, lets get on
42. 3:35Lets turn on mirroring for the Y axis ... pick the snake hook brush and start blocking in the upper body
43. 3:47And since I am not using a reference for the front view, I will just improvise.
44. 3:51You can add a reference for the front view, but I don't know how the creature will look like in the end, so I leave it out.
45. 3:57What I do is simply change between the Front, Side and top view, move it in shape and smooth it holding down the shift key
46. 4:05That's ok for now .. let's remesh it
47. 4:08When you drag the vertices, you are destroying the topology piece by piece.
48. 4:12This makes it harder to sculpt or can lead to unwanted side effects
49. 4:17This is why you have to retopologize the mesh from time to time
50. 4:20Blender has a build-in remesh function in sculpt mode which works fine in the blockout phase.
51. 4:25You can use it to fix your topology and increase the number of polygons for later phases
52. 4:30However, the remesh function can also destroy your sculpt when you have a finer mesh. So use it, but only in the blockout phase.
53. 4:37I will show you another method to prevent this problem in the 2. phase
54. 4:41Let's remesh our model, leaving the default settings
55. 4:44And add some legs!
56. 4:46So back to layout mode And press shift+a to add a cylinder
57. 4:51Decrease the size pressing S, and move it to position pressing G
58. 4:55And by pressing S Z u can scale it in the Z axis
59. 4:59A quick summary, since I dont wanna repeat myself and tell you the keys all the time
60. 5:03Each action like S to scale ... G to move ... or R to rotate can be used used freely
61. 5:10Or bind it to a specific axis when pressing X, Y or Z afterwards
62. 5:15After you set the position and scale, we will add a mirror modifier, choose the body as the mirror object And select the Y axis to create the 2. front leg
63. 5:24Let's duplicate the front legs, to create the back legs
64. 5:28And fix the position
65. 5:313D Modelling is ... moving vertices in place until you have the shape you want
66. 5:36To do so, you have to switch in Edit Mode by pressing the Tab key
67. 5:39You can now select Vertices, Edges, or Faces based by the Mode you selected
68. 5:45Holding down Ctrl when you click will select a whole loop
69. 5:49You can move, rotate and scale your selection, the same way you do with your mesh with S, G and R
70. 5:55When you need additional vertices, you can create an Edge Loop by pressing Ctrl R and hovering the mesh with your mouse.
71. 6:02Using the mouse wheel, you can control the number of edge loops you want to create
72. 6:07With this power of knowledge, let's create an edge loop on the back legs and move it to define the shape
73. 6:12And the same for the front legs
74. 6:15To save time sculpting, you can already refine the mesh a little bit. It is often much easier to do this in edit mode, than in sculpt mode
75. 6:24When you need additional vertices, feel free to add additional edge loops.
76. 6:29And when you're done, shift click both pair of legs and press Ctrl+J to merge them And apply the Mirror modifier
77. 6:38Now ... we want to merge our legs with the body. And we will use an awesome free addon for this
78. 6:44There are many free addons that make your marriage with blender much easier.
79. 6:48One of this Addons is called Bool Tool
80. 6:51You can install Addons by going to Edit - Preferences - Addons and type in the name.
81. 6:56When you find it, click the checkmark to install it
82. 6:58To use the bool tool, you must press N, go to Edit and expand the Bool Tool tab
83. 7:05After installing the Bool Tool, we will select our 2 objects and use the Union function in order to merge them and getting rid of the vertices in between
84. 7:14And back in Sculpt mode, use the Remesh function, to create a nice topology for sculpting
85. 7:20Now I will use the Grab Brush to continue the Blockout phase
86. 7:24Try to shape the body as you want using the brushes I talked about earlier in the Video.
87. 7:29Take your time, you have to get used to all the brushes, when to use them, when to smooth, when to remesh and so on. Practice makes perfect
88. 7:38There are many ways to reach the same goal, you just have to try out different things and see what works and what not
89. 7:45So your first task now is, to finish the rough sculpt with a low resolution. Feel free to pause the video and get to work on your model.
90. 7:52Or watch the next 20 seconds of timelapse where I finish my rough sculpt
91. 8:19This .... is the moment you stop.
92. 8:22Let's inspect what I did here
93. 8:24the silhouette gives you a rough idea of what this is supposed to represent.
94. 8:29the silhouette is an important part in art, because the human eye does not analyze all the details, but the overall shape.
95. 8:35You can see that it is a large animal that is very powerful, but from it's curves it looks peaceful.
96. 8:42We will make it horrifying by adding some spikes and refining the shape later.
97. 8:47and that's it for the first step. In the next part, we will increase the resolution and continue to go into more detail.
98. 8:54at your rough shape looks like.
99. 8:57I have created a google drive folder, where you can upload a screenshot of your blockout shape.
100. 9:04See you in the next part!
