Is it possible to find the mask colour of a loaded PNG out as I need to do some odd stuff with my PNGS after loading and it relies on knowing the mask colour.

Ta'

If they're textures, you could probably read pixels from the texture until you found one with alpha 0, and the color of that pixel is your mask color.

Mask color in 3D is always black (0,0,0)? Or do you mean alpha? or 2D mask color? There isn't any way to find the 2D mask color (apart from using a DLL).
