Shawn,
No, you can't control the amount of alpha blending this way. I just
used it as a psuedo code example of what I would like to do.
Yes thanks, I am Very interested in blending the textures at different
values other than 50/50.

This example (as well as Java3D) will blend between two textures.
However, you can not set the amount of blend, it's always 50/50.
I think Michael is looking to control the blend function a little bit
more (so am I!).
Am I misinterpreting this?
And can you control the amount of blend/alpha (ex texture1.alpha = .2)
directly - other than the actual alpha of each pixels?
