i am using the cod4 assets manager.
i want to know how and where could i use the detailmap
thanks in advance.
I've not got the game myself but at a guess it's either going to be a separate texture image (in the same folder or location as the original, or, in a separate 'details' directory) or they may have used the alpha channel on one of the textures. It could also be a 'generic' image in the same way Unreal applies the same 'detail' image to everything.
Sorry to bump this thread but you should perhaps try looking at the existing model assets and see how detail maps are applied (if they are).
I don't remember ever applying any detail maps to any of the models I worked on during my time working with CoD 4.
The only parts that were of interest to me were the diffuse, specular, and normal maps.
