Vertex Colour Rendering in Blender?

Recommended Posts

Does anyone know how to export your medium-high poly voxel/surface model with vertex colour info intact - and render this model within Blender, with as near to identical results as you would find in your 3D Coat viewport? [ PBR Materials/ Colors / bump info / gloss info etc etc ]

 

This would be great if possible - in many situations I dont need to rig or animate a model, so low poly version is unnecessary - this would speed up modelling/painting/rendering process massively!

It's not so much about seeing it correctly in the viewport, but about rendering the model in Cycles correctly - purely from the vertex colour info, possibly with gloss values etc, (possibly even from the new pbr shaders.) I'm just wondering how possible this is, or how far off it is, if it's not possible yet?

What colour info is saved when you export the high poly sculpt model? Is any of the shader colour info saved, along side info that might be on vertex colour 'layers' that you deliberately paint with the brush?

Am I making any sense? :)

Blender can import PLY files (.ply), which are text-based, very easy to parse, and include vertices colors.

 

You can always use the geometry node from blender internal and it works in the viewport in cycles mode but not in the render.

 

- you can access the vertex color for your Viewport (Realistic Material Preview) (right) through the Geometry Node/Vertex Color
- you can access the vertex color for Cycles Render (left) with the Attribute Node/Color
however both together don´t work
 
Why not to use the internal 3DC render room ?

I like the 3dcoat render room, but I'm looking to do at least some camera animation - stuff for video rather than stills

Vertex Colors are not (currently) supported; how many polys you can view/render depends on your system.
edit: also bump/displacement doesn't work. you have to use normal slot.

Thanks Carlosan for taking the trouble to ask in that thread.

With the speed of blender development [and 3D Coat development!] I'm sure that soon all these sorts of things will be possible.

I'm currently very encouraged about the speed increase Ive found using Blender cycles GPU rendering. As a result, I am shifting from Cinema4D towards Blender.

But 3D Coat is my 'staple diet' for modelling/sculpting/texturing.

Again, thanks for the help! :)

And if you ever hear of this becoming possible - I'd love to know!!
