Using Octane for Blender 2.90 [2020.1.5_22.0_xb] (Prime version)

An interesting one, after trying to install an addon (I didn't get past clicking on the install button, not being able to even choose my addon),
Blender crashed. I am now unable to ...

Always great to see new updates! Render times get faster with every update for me!

I know that this is a very late response but i was experiencing the same thing on R20 in the 2020.1_RC1[R2] preview.
It turns out that just creating a new scatter object and putting your objects under that seems to fix it.
Hope this helps anyone with similar issues in the future.

This is one of my first nature renders, and i'd love some critique and suggestions on how to improve!
