color issue with PRT Volume

Krakatoa for 3ds Max
#1

Hi

I am trying to convert some geo into particles using the PRT volume but I am having trouble with getting the color across on some objects and havent been able to figure out why. The colors show up correct on the viewport but its grey when i render. I have a magma to get the colors from the base object.

Anyone have an idea why this would happen? I have checked the normals on the objects as well.

Using kraktoa 2.6.1 and max 2012.

Thanks

Ok this is even more strange. If i go and view the texture in the material editor then it works till i close max.

The Magma that you show gets the MtlIndex, which assigns the given sub-material to the particle. So if the same Multi-Sub Material is assigned to the PRT Volume as to the mesh, in theory each particle should evaluate the diffuse color from the respective sub-material.

  • What type are the sub-materials being evaluated? Any V-Ray materials could cause havoc.
  • Are there any vertex colors involved?
  • What type of texture are you looking at? Any supported texture assigned to the Diffuse channel of a Standard material would be evaluated automatically by the particles, but we need to make sure the type is supported.

Can you provide a simple test scene (email it to bobo AT thinkboxsoftware DOT com) so I can see what you are doing?

Thanks for the response.

I have applied the same multisub materials to the PRT volume as the the object.I am using Vray materials. I will switch then over to standard and see what happens.

Switching to standard materials didnt work. Have sent the file to you.
