View Full Version : normal maps

07 July 2011, 04:16 AM
hello there. I have been using fusion for quite some years now. But now I have decided to shift to nuke. Can anyone tell me how can I convert rgb information to xyz information. Like it is done in channel boolean node in fusion. I want to relight a scene. I have rendered a colour pass and a separate normal pass in rgb. But I don't know how to change the rgb of normal to xyz so that I can add it to relight node. Please help me. I couldn't find any proper training video that will explain in detail. The video start from the point where the normal is already in xyz axis in an exr file...:cry:please help

probably you would copy the normal map channels into new channels inside the rgb image

Hello there,
I've found pretty good tuts on Digitaltutors about 2.5d relighting, you will probably get what you wanna do. take a look at it.
