2026.1 - H21.0.512 - Analytic Lights Broken + Render restarting on value change
Posted: Fri Dec 19, 2025 10:02 pm
Hi there, a couple of bugs I've found in Octane 2026.1.0
Firstly Analytic Light light beams appear to be broken - when light beams are enabled in Post Processing, the render is fully black. Changing the Medium density doesn't fix this.
I tried this using the Octane Render Setup SOP and a Octane ROP node in the ROP context.
Secondly changing any value in the Render Target (again in SOP setup and material context) causes the render to restart, even values such as Hotpixel removal and Exposure for instance will trigger an IPR refresh.
