OctaneRender® 2026.2 [current 2026]

[mojave]

Thank you, would you be able to provide a scene where this can be reproduced for us to test?

I share this scene here:
Caustic_Breakdown@plastic on glossy floor@rough 0.15 at real light source at the almost real life_6000x3375.orbx
But you can change the kernel from PT to Photon Tracing (see above image about kernel settings).

Same problem for lastest version of OR too.

Thank you.

Best regards.

Thank you for sharing, we will investigate this. If this is blocking you please let us know.

Ok. I've removed the attachment.

For AOVs, it would be very nice if Light AOVs also had the option for direct reflections and indirect reflections per light. This is possible in Redshift and gives very nice freedom in compositing.
I know you can achieve this with Output AOVs, but it would be great to have an out o -the box option for denoised Light AOVs.

In Octane Standalone 2026.2 the displacement map on the layered material does not work.

SOLVED (atleast for now) havent had crashes for a few days now, will keep updating.

fix that helped me.
1. uninstall gpu drivers with DDU (no network, safemode, etc. there is tutorial on youtube)
2. install latest drivers
3.restart pc
4. run pc as usual
5. CLEAN SHUT DOWN pc, hold shift and press power off button in windows (not physical button on case), just keep holding shift till it turns off.
I tried DDU method 4 times, and pc still crashed, turns out windows quickstart keep some trash dll files that are getting wiped after you clean shut down, these dll files kept crashing drivers no matter how many times you reinstalled it, its like a cache memory. atleast it helped for me.

Ok. But Win11 may be issue... - Have you installed KB5074109 update?

I stay Win 10 for best stability because my RTX 4090 doesn't get any issue yet... on NV Studio driver, after many, many times of average 16 hours per day.

This black screen bug started back in autumn 2024! I don’t have that update installed, but I didn’t have it before either. Ever since NVIDIA started using AI in driver development, there hasn’t been a single stable driver in the past year and a half.
This is a widespread issue, and it is related only to the drivers — the graphics cards themselves are working properly for everyone.
You are using the Studio drivers, but most people use the Game Ready drivers, since other software depends on them, including Unreal Engine 5.

Your CPU, mboard and RAM system are bit too old due to "DDR3". Why do you need "workstation" for both CPU and mboard?
Therefore, you need to upgrade to new CPU Intel (not Core 200 but yes 14th gen), ASUS mboard and DDR4 or DDR5.

I have had 3090ti since launch no problems. Bought Asus 5080 about 2 weeks ago (April 6th today) my display crashes fans full speed and can still hear apps. Plugged my 2nd monitor into mobo hdmi and when this crash happens that screen still works just my HDR connected to GPU primary card goes black now. Been reading all the comments still no answer. Imagine giving 1800 dollars for a gpu that isn't stable? I bought a new psu cord from microcenter yesterday, ddu, reinstalled. At a loss for words. Sometimes I'll get a few hours out of play, sometimes a few minutes. I have 1000w corsair psu, now new gpu cord is 650 watt corsair after market cord. 9800X3D cpu and 32GB of Ddr5 vengeance ram. I know my hardware is fine. If anything the 3090ti used more power than 5080. I've tried using studio driver vs game ready driver. Extremely frustrating. Imagine a new car comes out with this many issues recalls on it would be immediate. But nvidia just ignores this hoping it would go away. And I'm not even playing a game that comes close to maxing out the 5080. I just wanted the upgrade because a coworker bought my 3090ti off me for 500 bucks and I had enough to upgrade. If nvidia can't fix this crap I'll be going AMD I hear the 9070xt is running great on reddit and they paid half the price I did for this hunk of technology failure. Thanks for listening any tips are welcomed!

For me... I can't get any textures, geometry files, orbx that are stored on my network drives from within octane.
It's wotking fine when I'm on 2026.1 but no chance in 2026.2 (e.g. \\192.168...\item.orbx)
