Maps/materials to Arnold

[bldpsnmlt]

Hello!

Want to redo my textures by only using Arnold materials to benefit from the GPU renderer.
Right now im using composite mapping with uvw unwrap modifier, which did a well job.

I´d like to ask for advice on how to build the same setup with Arnold materials.
Already using the Layer RGBA, but getting different results like this:
Upper eyebrows material is standard, lower is Arnold

Attached example files, save with texture and alpha.

SaveTextures.zip

Note: Its important for me to have the transition from bitmap to bitmap with channel ids.

Thank you in advance

I would suggest using the Arnold Composite shader, but it seems to be missing atm.

Thanks for responding.

Missing in general or in my scenes.

Also could you tell me, if my texture files are compatible with Arnold? Read somewhere to use textures from Arnold libraries for better results.

Could that be the reason, why the eyebrows look different?
