OctaneServer runs quiet unstable, eats up a lot of memory and transfers data quiet slow.
First of all: I tested the maya demo plugin and the scene transfers much faster, but maybe no bug at all.
Biggest issue is the memory usage. I have a scene in blender that cannot be rendered directly in the app but uses only 3gb VRAM in the standalone. Also BlenderOctane/OctaneServer seems to not clean empty memory after rendering a couple of times the memory is full and i have to KILL and restart the OctaneServer.
Thats really annoying because i cannot light my scene in blender anymore since it uses too much VRAM in blender. Even if i let blender stay open and use Octane Standalone on another virtual desktop it works...so its not the blender guy that eats up all the VRAM.

Another thing i just recognized: If i have a alembic cam in blender and write the whole scene out to .orbx the camera has messed up transforms. Maybe Euler rotations? If i import the same cam i used in blender to the standalone, the camera works well.

ACES files are not found. I'm using a global profile (OCIO EnvVar). Blender(not BlenderOctane) picks up the color profiles perfectly while BlenderOctane gives me errors:
Color management: using fallback mode for management
Color management: display "ACES" used by scene not found, setting to default ("sRGB").
Color management: scene view "sRGB" not found, setting default "Default".
Color management: sequencer colorspace "ACES - ACEScg" not found, will use default instead.


Thanks.

Hi,

Sorry to hear that you have experienced issues with the Blender plugin on Linux, and apologies for the belated response.

Would you be able to supply the orbx file for testing by any chance? I will do what I can to analyse and replicate your issues. I will need to determine whether this is specific to Linux, or is an issue across all of our platforms.

Cheers,
Azen
