OctaneRender® 2026.2 for 3ds max® v26.5

[Elvissuperstar007]

It works normally and does not crash until I change the lighting. If I reopen the scene and immediately switch to this lighting setup, the scene renders without any issues. However, as soon as I change the lights and the Environment again in the same scene, 3ds Max crashes without any error message.

This issue does not occur in Octane 2024 — that build is stable. Here is a test video: I didn’t even need to work for 20–30 minutes; something immediately triggers a crash when changing the lighting. And this is not the first scene that behaves this way.

My system is fully capable of running Octane Render. Yes, the CPU is old, but it is still powerful — 10 cores and 20 threads, which is quite solid. Most importantly, it runs cool and remains reliable. The RAM is also working properly: 64 GB of DDR3 at 1866 MHz in quad-channel mode. In quad-channel, it performs faster than DDR4 in dual-channel mode.

Considering the global memory crisis, older system builds will remain relevant for a long time. Of course, this is assuming OTOY does not suddenly start requiring AVX2 instructions, which would be unfortunate, since they only became common in CPUs around 2016.

My operating system is Windows 11 Pro. I have not installed the latest update, as I am concerned about potential issues from Microsoft.
