Someone's going to have to explain terrain textures to me. I have a tarmac texture that I want a bit shiny, I read somewhere this could be achieved with an alpha channel being used as a 'gloss' map. I tried that, but with no success. So I reverted to the standard color/gloss/normal/metalness workflow hoping alpha_core.fx might fall back on that if it's presented with those maps. It does not. So what am I doing wrong? How can I get this texture (attached) to have both a normal map, and a specular shine controlled by a gloss/roughness map?

Attachments:
tarmac06.dds - .dds with an alpha channel, GG seemingly ignores the alpha channel
tarmac07_color.png - .png with no alpha, GG refuses to load this
tarmac07_gloss.png - .png with no alpha
tarmac07_normal.png - (weak) .png with no alpha

Gloss is supposed to be the alpha in the diffuse or color map for pbr textures now.

Save it as dxt5 compression for use.

I have tried DXT5 but it still isn't recognising the alpha channel. Is it perhaps because it is interpolating it? DXT3 appears to have explicit alpha channels, which surely is what I want?

hi Avenging Eagle if you are using PNG they have to be saved as 32 bit
