Hello!
I have a problem with rendering polypaint from ZBrush in Arnold in 3DS Max.
I've used this tutorial: https://www.youtube.com/watch?v=ByFhQg2egS8
and the plugin. The problem is I don't know where I can find Vertex color in materials section while I want to use Arnold for render. At this moment I can see the polypaint in the viewport, but while rendering, it's just the simple gray material.
I would be really grateful for help 🙂
I jsut made a video from scratch showing how to pipe a vertex channel and filter any sub channel through the USER_DATA node and Shuffle node.
- You catch - any - channel data with the USER_DATA nodes, and type in "uv_0" to catch channel 0
- You can split the channels up into seperate components if you need/want - with the Shuffle node.

Let me know if you can see this video, the uploading accross the board seems pritty busted at the moment.
Exactly, although that wont work on Arnold GPU, yet.
But with the OSL node, you can add a couple of lines of code and exit to a float inside the UVW map and do the splitting directly inside the node.
The default node only sends out a 3 float structure pr default.
You can also use the ColorJuggler.osl to filter in same way as Arnold Shuffle node. Its called Components (Color) in the shade node hirachy found in Math/Color.
Did you solve it? I' am facing the same problem and I can't figure it out
