Octane Area Lights are broken in 31.12
Posted: Mon Oct 26, 2026 5:09 pm
I have submitted an official support ticket for this, but wanted to post here in case anyone else has noticed this behavior as well.
In Octane 2025.5 Blender (custom build 30.11) - Octane Area Lights worked as expected between light power/size relationship. However, Octane Area Lights in 2026.5 (Addon build 31.12) there seems to be a bug, you do not get the desired/same result using the same metrics. HOWEVER, it seems to be specifically the Octane Area Light itself, if you build the same light/same node setup, using a Mesh Plane, you will get the same result as in 30.11. Scale, size, everything else is exactly the same.
See screenshots for comparison.
