Solution for server start problem I encountered on CachyOs
Posted: Tue Nov 10, 2026 11:07 am
Helllo everyone, freshly new Octane Blender user here.
I wanted to post a small solution I found trying to start OctaneServer on cachyOs.
It seems that cachyOs rolls out with
it was giving me this error:
By forcing the library
with the 31.12-stable:
(code run from the OctaneServer directory)
Hope it can be helpful to someone or to devs to make a workaround for this linux distribution.
P.S.
Was a pleasure to meet linograndiotoy in person at Blendercon2026 in Amsterdam, did not knew him before, but i got interested in his work and decided to give Octane a go.

It seems that cachyOs rolls out with
