Override Proxy Material

Hey there,
is it possible to use only the geometry of a Proxy item and change the Materials in the Shadertree?
I have multiple high-res meshes which must be rendered with several different materials. So I thought i use proxy items and define the Mesh in the Scene.
Thank you in advance
Edit: One solution to this is to use the Modo Proxysystem. But you have to enable Use Rendercache which in my experience in very unstable. Is there a way to use this workflow with the OctaneProxy item?

Hi
Mesh Proxies are treated as Octane Scatter transforms - and therefor all proxies of a given mesh will render with the same Octane material. However with release 3.07.0.125 you have:
- Added an instance id to each Scatter transform (ie. each Replicator particle source will have a unqiue instance id). The Instance ID is sourced from the Modo Replicator source IDs. The new Texture node types Instance Range and Instance Color can be used with these id's.
which should allow you to tweak the colors, etc for each proxy instance.

Hi Paul,
i'm afraid this doesn't work for me. But thank you for the idea.
I thought the ModoProxy with RenderCache Solution would work for me, but i can't get the rounded edge option working. I think the Problem is that i can't use "weld vertices" on a modo Proxy item.
Do you know a solution the use rounded edges on a ModoProxy?
Thank's in advance!

Yes, I doubt the current Octane round edges solution will work with the Modo render cache supplied geometry. However Octane have stated they are still working on round edges, so perhaps in the future this will be possible.

Set the Particle Id of each instance to a whole number (ie. 1, 2, 3, etc). Then add an Octane Instance Range to the Octane Override and plug it into the Input of a Gradient, and set the Octane Instance Range Maximum ID to the largest number to entered as a Particle Id.
