Hi, Thanks for the hint with the textureChunk finding, it works great. I have a question though : I set my texture on a slot by calling ChunkMaterial::addChunk, which takes the texture chunk ptr as first parameter. When I do that, am I sure that if it's the first time I call addChunk with a TextureChunk on this materialchunk, the texturechunk will be assigned the slot number 0? If I call a second time addChunk on the same materialChunk with another texturechunk, will the slot number be 1? etc. What about the second parameter of the addChunk function : is it a good way to provide our own texture slot number? Like that, I would call addChunk(texChunk, slotNumber), and I will be sure that this texture chunk will be assigned this slotNumber, instead of counting the times we've called addChunk on this material before. Does it work like that?
Anyway, I tried with the debug libs and it doesn't seem I have any OpenGL error. Still, I'm not sure about what you call "texture definition" : I generate myself the data of the texture, by feeding the data pointer of the image pointer (which I get by calling getData() on the Image) with UChar8 triplets. And I use the format "OSG_RGB_PF" : img->set( Image::OSG_RGB_PF, _iBar, _jBar, _kBar, 1, 1, 0); Is it related to what you call texture definitions? Just to know what to look for, because my log file is awfully enormous, what kind of messages would I get with such an OpenGL?
