Re: does anyone know how to use gimp and shadow process height maps?

i have a rather good " Shape from shade" program but it is LINUX ONLY
there are no windows or mac binaries

but it might build from source using MinGW on Windows

that and ISIS3 is what i used for that example you posted

Re: Asteroid 231937

trappistplanets I embed the two textures in the cmod , so there is no need to add them to the ssc file and this is an odd bug "." in the name should not cause problems and cmodview and celestia use the same base code for rendering ,so there "should" not be a difference Regarding ...

Re: Asteroid 231937

In cmodview, the model was black. When I removed the dots (.), I could see the texture but still not in celestia. odd bug ? the only thing i can think of is your built in graphics chip can not handle 4k textures on a mesh here are 2k versions ( the normal map had to be remade from a 2k height map )...
