I'm working on a model for comet 67P, but the CMOD model has material bugs.

The (CMOD) model is in ASCII format for better visualizing (the bug also happens when I save it as binary file).

In the model's material definition I wrote "diffuse 1 0 0" (= red (just as example); blue marker),
but CmodView's material editor shows "Diffuse: 0 0 0" (= black; red marker),
and the model is displayed in white.



Original model source: https://scifleet.esa.int
Converted to obj by Blender 2.79 (3ds format is not possible due to its 65535 vertices limitation, but the model has 740338 vertices).
Then I used CmodView to convert it from OBJ to CMOD (without materials, added them with 3DS 2 CMOD Converter's fix function).

Why isn't the material shown?

Here the fbx, obj and cmod files:

That's your problem, CMOD View bugs out directly OBJ files to CMOD.

is this the texture you are trying to use ?


if so it is too complex a UV mapping to work for a cmod

than is it possible to bake it into a cylintrical texture, just like how i can bake orthographic views of an object into a flat map using blender
if one is able to do it with a sphere or irregular shape from orthographic view, than in theory it should be possible to "covert" that map to a flat cylintrical map

it is possible but a cube map would be better

and cmods support a cube map

I'm not trying to use a texture, I just want to find out why the comet will be rendered in white, not in red (see post #1)

Ah, I found a way to fix this: open the model in Blender 2.80 (newer versions have features that I don't need and are laggy a bit) and apply a material (e.g. base color white) to it before converting to CMOD.
