Replicate Bump Normals pass

[kiryha]

Hi, guys,

How can I replicate Bump Normals render element with standard Maya shading nodes?
E.g. to replicate Normal Camera I can create an ExtraTexElement and connect a SumplerInfo.NormalCamera to ExtraTexElement.vray_texture_extratex.
Is there a way to do the same for Bump Normals?

The issue with the standard element is that it has XYZ channels instead of RGB and it will cause issues in our pipeline.
Maya 2016, VRay 3.40.006

What kind of pipeline are you using? A solution may be to save only the BumpNormals pass in a different format, i.e. .tga seems to work fine.

We have a custom studio pipeline with a lot of Nuke tools which would be "confused" if EXR will have X, Y, Z components...
I found the solution, the Maya Sampler Info node contains everything I need (Vray Bump Normal) if I add VRay attributes (Attributes > Vray > Additional outputs), so I can plug them int ExtraTexElement.
Thank you!
