Hey,
I have problem with rendering Instances of Hierarchies (a folder containing several meshes). The do not render it the original meshes are hidden. If they are not hidden - them all of them render (which is undesired).
Octane pops up a dialogue box saying something like "Error getting scattering node". Not sure because I can not reproduce the pop-up but my Instanced geo still doesn't render
this is not the first time this happens. The workaround is to convert the Instances to regular meshes .... but that's far from ideal.
Funny thing is the Log doesn't show any errors.
