I'm working on programming an engine and I'm testing blendmaps. How would I go about putting texture B over texture A where texture A would show through the alpha in texture B but texture B still has its diffuse texture?

My computer surpasses all the technologies of the day. What computer do I have?

So, like this?



In that case, the correct mode to use would be D3DTOP_BLENDTEXTUREALPHA,
You'd use this code to set that up:



Hope that helps!

Exactly like that, thanks.
I tried just about every other blend mode other than 13 and of course it ended up being 13.
