Proximal Shader for C4DtoA

[Jonny_Nielsen1]

question about proximal layer in C4dtoA

I have a landscape with Cloner trees standing on the surface of a terrain, with the standart cinema4d render I can create a shader, with a mask driven surface that only shows up the places where there is a tree standing ( proximal ) - I want to render the project with Arnold but I can't finde a solution for the Proximal shader that I use in the cinema4d shader?

Is it posible to get the c4d proximal layer data into the Arnold material? or create a proximal layer within the Arnold shader?

Best regards Jonny Nielsen

There's no direct equivalent of the Proximal shader in Arnold.

It basically calculates the distance from the shading point to the position of each cloned mesh. You can build a graph which does that for an individual object, but not for a Cloner, which is exported as a bunch of objects/instances. I believe it would require a custom shader and some custom export logic.
