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
