Hello guys, i'm working on a little game that i plan to release on XBox, but i have a little problem. I have a .fbx model that has different textures for different meshparts, if i use basic-effect XNA automatically assign the right texture to the right mesh part, but when i use a costum effect i don't know which texture to assign to the right mesh part. I've been googling for awhile, but most of the question are either not-answered or answers are completely useless.

Now to resolve this problem i've thought about 3 solutions, but i have no clue how to implement them :

I ) Hard-coding the texture for each meshpart, saving them in a configuration file. I don't like this approach because it's not dynamic and it's way too long

II ) Compressing the textures into a single texture. This won't be bad, but i don't know where to look for such tool

III ) Extracting the texture information from the model. This is IMHO the best solution and what i should try to do, since BasicEffect knows it there must a be a way to get it from the .fbx file, but really i have no clue.

Thank you again. I'd be glad if you could provide a code sample or link me a paper or tutorial.
