So I have a model that has skins, and a lot of materials, thing is, I have counted the materials to make sure it does not go over the limit, it just hits the mark, 32 materials, however, Crowbar still gives the error, ERROR: Too many materials used, max 32

There are the exact 32! There are no more, so why does it still appear? What, Valve only expects us to have anything UNDER 32 and not exactly 32 itself?

Anything that could be done?

Thanks
