Hi,
thanks for the revert. I have enclosed the network I was referring to (which is obviously a very simpler one in comparison to the one referred by you).

I had looked at Layered Texture as an alternate to this network, but have not been able to figure out the exact way to go about it. Would appreciate if you can help on this.

Secondly, I am not clear on the statement you made on the transparency - Maya does not discriminate between the channels....

Could you elaborate on this?

Thanks

GP
