I'm currently running Octane 4 with LightWave 2015.3 , happily, with two 1080Ti cards.
I also own LightWave 2018 and 2019, but haven't migrated to them yet for legacy reasons, and because Octane is my main renderer and it works as is.
Question 1:
What are my upgrade options?
I have a GPU rig on my main PC I'd like to start populating, and I have access to other cards on the network. I'm happy to move to LightWave 2018 or 2019 if I need to make use of newer versions of Octane, although backwards compatibility with LightWave 2015 would be a bonus.
Question 2:
Can I run two versions of Octane at the same time - so V4 with LightWave 2015.3 and then a new version (Octane 2018?) with LightWave 2018 or 2019? This way keeping backwards compatibility with older projects, whilst getting to use new bells and whistles with the newer combo?
