Using VR with C4D to make Gestural 3D Assets
by Collin Leix
Scene 1
Blend Titles - How to use C4D/Oculus Medium pipeline to quickly sculpt gestural detail
Starting with Styleframe + Base Geo in C4D
How to bring in reference image and lock to camera
Build Base geometry that’s locked into styleframe. This will be ‘home base’ in VR
Use Vertex Colors to paint only the polys that the camera sees
Export FBX
Bringing Sculpt into Oculus Medium
Importing Reference Image - Styleframe
Importing the reference Base geo you just made in C4D. How to lock it so the orientation stays consistent with c4D workspace
Basics of sculpting in Oculus medium - (won’t go into a terrible amount of detail, but will suggest resources to continue learning). How to add Geo on a new layer + stay organized
How to add Color
How to optimize and export geo
Bringing FBX back into C4D
Importing FBX from Medium
How to visualize Vertex Colors
How to break polygon groups into separate objects
How to optimize Mesh with QuadRemesher plugin
Subtle animation with a Plain effector
Scene 2
Crocus - How to use C4D sculpt tools to Modify VR sculpt, + Use Vertex Maps and Deformers to Animate
Using C4D sculpt tools to modify and enhance VR sculpt
How to use the Weight tool to select and softly paint Vertex Maps
How to use the Restriction tag and Deformers to move only where Vertex maps allow
Scene 3
Lovebirbs - Stop Motion animation in Oculus Medium + C4D
This process is tedious but it was a fun experiment!
Show the reference Cel animation. A cartoony bird flies onto the scene. Some frames show distortion that would break a normal 3D rig. So what if we re-sculpt the frames that are outliers from the main design?
Breaking the cel into individual images. We will re-sculpt only the ones that are absolutely necessary.
Organize frames in VR
Sculpting individual frames in Oculus Medium, + Export
Bringing sculpts into C4D, organizing them in Nulls
Turning nulls on and off to show stop motion progression
Using Sculpt tools to match the styleframe
In addition to the Stop-motion technique, Use Vertex maps + Deformers to animate
Scene 4
Quill- Using Oculus Quill for Gestural linework
This is the tip of the iceberg for Quill - there’s all kinds of cool animation you can do within the program. Today I’m just talking about creating still 3D assets in here.
Importing Reference image
How to create a new paint layer and Color pick from it
Choosing a Brush
Importing 3D into Quill. Quill can read Vertex colors. You can paint around a 3D sculpt you made in Oculus medium.
Quill draws in strips instead of one mesh, but it can also be used to make organic geo, thanks to Volume mesher in C4D
Exporting an FBX - use ‘Gamma’ choice for color export, instead of Linear.
You can also export splines from certain brushes
Bringing it all back into C4D
Using Volume mesher to connect separate quill marks into one mesh
