This model is composed by just two squares, each one of them textured with a different texture. your filter builds a correct atlas texture but it assigns wrong tex coords to the mesh. About the rect packer what are exactly the asserts that worry you? From what i could see you they trigger on very trashy situations that should be cleaned before (zero sized textures and so on). I could have missed some, so what assert()'s did you refer to? cheers -- Paolo Cignoni -- Senior Researcher Visual Computing Laboratory - ISTI - CNR http://vcg.isti.cnr.it/~cignoni ISTI - CNR Via Moruzzi 1, 56124 Pisa ITALY |
