Houdini, particles, groups and material node Tweet

[thinkinmonkey]

Hello,
just started to use Octane and I would like to be confermied this.
It seems to me the material node with groups works nicely when geometry is incoming, but not when there are particles systems, I can see them purple in the IPR.
Is that true? Will be possible to render different particle systems with different shaders?
Thank you
