Plane displacement and instance placement

I am working on a ground plane that i displace in octane, and i would like to place dirt and thing on top of it...

I got a plane on a layer and a bunch of point for the instances.

is there a way doing this all in octane, or must i displace the mesh in LW modeler and conform points on the second layer in order to have well placed instance?

Doest the raycast node work in octane and how?

Sorry, It's been more than 20 years since I used Lightwave. I thought LW let you offset instances based on a texture map. As long as you can generate your instances from the base, pre-displaced geometry (or a copy of it), then drive the offset position of the instances from that texture map or a version of it, you should be able to do the same thing. Good luck!

I'm afraid that currently the plugins can't have access to the Octane displaced mesh, so as you say you are going to need a mesh displaced using the LW native displacement system to place the instances.

Thanks,
