intersect() inside material builder

[nuki]

Inside a material builder I would like to use the intersect() function. As I couldnt get it to work with the op:/obj/path_to_mesh syntax or any other way I was wondering if using intersect() is even possible in mat context? Also, is there a simple way to return the scene path to the geo the current sample belongs to?

it will work but only with geometry stored on disk. geometry referencing in shaders in general only works if stored on disk.

I'm not sure if that is always true.. have a look at this very simple example

pretty interesting, was it always like this? i was doing some stuff with point clouds in shader and never could make this work in earlier versions. anyways i'm glad it works now

At least pointcloud stuff worked even back in 15.5. https://www.youtube.com/watch?v=eOWUJZ1vsFU

from 25:50 on it is demonstrated

If working with intersect() is new I can't say, but I don't think so
