normal map with alpha?

olivierth

Hi,

I want to have a normal map with an alpha. I tried saving the normal maps with the alpha as a .tga and imported with the TC_NormalMap compression but when I get in the material editor, the alpha looks perfectly white. I double checked that the .tga has the right alpha.

Is it possible to make it work? Is it a better idea to have no alpha on the normal map and simply create another texture for the alpha?

Thanks.

Is it possible that TC_normalmap remove alpha channel after compression?

Thanks. I just found out that there's a TC_NormalmapAlpha compression. The one I was using can also have an alpha but only a one bit alpha. That's why the whole thing was white.

ah yeah, makes sense. Oh well, glad it works now!
