FAQ

My textures look grayish, like they would have a limited color space. What could cause this?

Answer: Be sure to create your textures in the sRGB color space. Otherwise they will be displayed not correctly. Also, don't forget to call tex.setFormat(Texture.FSrgb) or tex.setFormat(Texture.FSrgbAlpha) after loading the textures.

Bumpmapping does not seem to work

Most of the time I disable bumpmapping while I test models, and it might be I accidentally committed that, so check that its not disabled here.

My normals / lighting seems to be wrong

If your object has a bumpfactor of greater than zero but no bumpmap applied, the normals might be off and thus look strange, also affecting the lighting. Ensure the bumpmap factor is either 0 or you have a proper bumpmap applied!
