(Question & Semi-Product Suggestion) Can V-Ray Sample and then Edit Normals so we can make Directional Masks ?

[stevejjd]

Hi guys

Im trying to Master the art of Masks. - I want to make pre-sets like in Substance Designer but for V-Ray and then I want a node for rapid baking to UDIMs and or PTex.

I found this old tutorial where Jens makes a mask by extracting and rotating the surface normals. https://www.youtube.com/watch?v=YLxCp90SYyA (Just skip through it quickly) - He basically samples the Normals then rotates then so that he can create a Mask. ------> Can V-Ray + 3ds max do this? or do I have to send the model to Mari?

It would be cool to make directional masks like Up Down masks for Dust accumulation on Normals that face up and then Dirt accumulation for Normals that face down.

For now I am playing with the VRaySampleInfoTex but you can't rotate the Normals - Also would be cool if you could plug in a Vray Color to the Normal Direction to have control over the rgb multiplier

You can make those masks, custom directions and all, with the falloff node in Max.

Hey - Look at that. See my comment above "Yeah - I?ll"........I did not write that at all. I remember writing a response using my iphone. Just be careful making posts using your phone because it will scramble your message.

You can use the VRaySamplerInfo Renderelement to output all sorts of normal and position passes: https://docs.chaosgroup.com/display/...RaySamplerInfo
