finally more news about octane render 3 plugin for Ue4. Still not sure how exactly it’s gonna work tho.
‘‘We have a new developer who will be taking over the UE4 plug-in shortly, and will be integrating the Octane 3 functionality (i.e. baking) within the integrated plug-in. The idea is you can easily load an ORBX scene from Octane into UE4, with Octane handling light probes, baking and more, either live or offline.’’
