This is just my two cents. Is your texture follow the isgl3D requirement? from isgl3D Tutorial 3 – Texture mapping http://isgl3d.com/tutorials/4/tutorial_3_texture_mapping For standard image files, the image size must be factor of two compliant: eg 64×128, 256×32, etc. For pvr textures, the image file must also be square: eg 64×64, 256×256, etc. Hope this help.
