Excuse me for hoping a ride on you thread wagnerov but I think this question is a continuation.
I've been wondering, for a while, why my addon textures, especially grass based, always looked different against the default grasses and having seen your terrain work mianiak and read your comments I searched for more info. Came across a thread from 2009 between R Soul and woochoo which put it into perspective. Thought best way to learn is take apart a default grass, with multi & add, and put it back together. Did that but ended up with just the diffuse texture (thats what it looks like) in BTB. Sort of sparkles.
I have the 3 images - diffuse - multi & add loaded into XPacker and they are listed together in Textures. I made the latter 2 half size of the diffuse.I tried with alpha trans and chroma and I have saved textures in DXT3 and DXT5. What settings are used to get this all together please.
