There is a bug within the DDS loader for the Texture resource. When a non-square texture is used (something like 1024x512 will do it), during mipmap loading, the smaller dimension will be reduced to 0, causing OpenGL to throw an INVALID_OPERATION error. Below I have a small fix that prevents this problem. In egTextures.cpp, line 326 replace: Code: pixels += mipSize; width >>= 1; height >>= 1; with: Code: pixels += mipSize;
width >>= 1; if(width < 1) width = 1; height >>= 1; if(height < 1) height = 1; |
