For some reason I can't get my gloss map to work in the engine. I tried placing it in the normal's alpha channel, then inside the specular map's alpha channel, but neither worked. I can adjust the smoothness level with the slider but I can't see my actual gloss map taking effect (I'm supposed to see some "stains" with my gloss map but I'm just getting plain smoothness). Everything was exported properly with the crytif plugin (It's not a requirement anymore but I just wanted to make sure anyway). How can I fix this?
