Mario (lmg) suggests we'll throw in a commandline for how to do batch convert in image magic. The inversion we're talking about corresponds to ctrl+i in photoshop btw. It's essentially (in 8 bit): val_new = 255 - val_cur; applied to red and green. This will make the normals stored in the map correspond to tangent space generated from the geometry we actually export in all of our exporters. Like I said since we have already done an overhaul on how normal maps work to get them to work properly and support mirroring, face/face verts order-independence, welding independence etc. We might as well be sure to get it right now. Seems like now or never, And this is a small adjustment on the change that is already in anyway. Cheers, Morten.
