Vray to MtoA automatic conversion

[john.paul.giancarlo]

Hello, I was wondering if anyone knows a good script to convert Vray shaders to Arnold.
I have tried the script in the utilities menu but it does not convert the shaders correctly, a lot of Vray nodes, remain connected, and other wont convert to its counterpart, .. The VrayTriplanar node, fall off noses, etc.. .see image bellow

I am not even sure what would be the best node to change for a VrayFalloff, I think aiFacingRatio is similar in results but not the same at all.

If anyone knows a good workflow, or script would be highly appreciated.

I am looking into writing a script but appreciate the complexity of this and that it would take a lot of time to finish correctly.

I'm not too familiar with V-Ray shaders but it looks like the VrayFalloff is a dirty hack for fresnel? You shouldn't have to worry about that with Standard Surface. What was it connected to?

There actually is a VrayFresnel as well. VrayFalloff provides the same Front/Side but allowsfor differing falloff types such as Towards/Away, Perpendicular/parallel, Fresnel and Distance Blend. It allows provides access to camera, local, and world axis directions all within the VrayFalloff node.

You could also use the aiStateVector node to get access to position, world and so on, like within the VrayFalloff
