I'm trying to retexture a skin for my custom unit. The new texture works when I overwrite an existing .dds file. But I don't want to do that, so I duplicated and edited the rigid_model_v2 for my custom unit and changed the path of the diffuse map with HxD Hex editor. I changed the variantmeshdefinition for my custom unit to use the new rigid_model_v2 file.

The game starts up fine. But then it crashes while loading the custom battle where the new unit is in. Any help??
