How to raytrace render surface color of a mesh

Rendering

Hi - I think I’m missing something basic here, but I can’t work out what. Hopefully someone can point me in the right direction:

  • I have a closed mesh (a polygon .ply import from a fluid dynamics model).
  • In shaded view you can see how the polygon surfaces colours transition from one to another
  • These colours are maintained in viewport render view
  • However, when I try a raytrace render, the material takes over (in this case the default material so it renders grey)

Can anyone tell me how to raytrace render the original colours from the imported mesh?

Many thanks,
Dan

There is not a directly supported material or way to do this, but there is a “secret” material to do this for Raytraced. Run TestShowPrivateContent, then in the Materials panel add a new material, select as type Cycles VertexColor.

Assign this material to your meshes, then switch to Raytraced.
