I keep getting this error message when trying to render with krakatoa from a sequence of prt partitions…
WRN: The material: 01 - Default requires map channel 1, which is not available
im not sure what to do to stop it doing that, i tried to change the channel to 2 or 3 on the material but it just changes to missing those channels instead?! could anyone tell me what i’m doing wrong?
thanks.
This is the same as regular 3ds Max renderers - if you are using a texture map that requires a texture map channel, you have to provide that channel.
Texture Coordinates can be generated from Particle Flow via its Mapping operators, Box #3 subOps or the Krakatoa Geometry Lookup operator; PRT Volumes will acquire them from the source geometry; Krakatoa Channels Modifiers can produce any of the 100 mapping channels either procedurally or by stealing channel 1 from geometry via the Surface operators. Alternatively, a texture map could be switched to object or world coordinates so it does not require explicit mapping coordinates.
But the principle is the same as with any geometry rendered with a map - if you want to use texture coordinates, you have to generate them one way or another.
