irredit problem(solved)

Hi anybody know how to use a seperate grayscale alpha map in irredit?.
Thanks.

It may not be possible... is it something you can do in irrlicht itself without using shaders or editing the source? If not then you can't do it in irrEdit and even if you can do it in irrlicht doesn't mean you can do it in irrEdit unfortunately.

separate alpha maps are currently not available for Irrlicht. If someone could tell me how to adapt the d3d alpha_channel material to use an alpha map from slot 2 I'd add this feature to Irrlicht (so alpha_channel would become a solid+alpha material in case two textures are provided).

Okay I guess I'll just create a new alpha channel in photoshop.
Thanks!! .

I found a webpage covering it...

One poster mentioned using shader code for d3d. Sounds like a tex2d() func call.

you could always write a small shader, multiplying the alpha of the the model by the alpha map.

Good idea, it seems like you already have OpenGL figured out?

Yes, OpenGL does work here locally. So I'd just need the d3d render states which use the RGB from the first texture and alpha from the second.
