I am using dds textures on my model as it seems to be the format with the smallest file size and I am trying to keep my model under 20mb before releasing it to the comunity.

I have run into an issue though; For the skin texture dds works great enabling me to have a 2048 by 2048 texture with a minimal file footprint but when I try to use dds on the normal map it wont let me assign an apha map to control the specularity.

Does anyone have any suggestions?

Thanks in advance.
