I have a DX shader (.fx file) from the max install called "StandardFX.fx"
Its fine in its function HOWEVER for the Ambient Occlusion map slot it uses (unwrap) Map Channel 1.

I am not a coder

but in the code is there an easy way to identify where this Map Channel is defined as #1 and change it to Map Channel 2 ??? (i.e. a different UV unwrap layout for AO)

thanks
Ivon
I can copy the code here if needed…
