OctaneRender 2026.2.0.1 for Houdini Production (2026.2.0.1)

Did you have a chance to look into it?
I have to work with a lot displacement atm and it is not usable at all. Crashes every minute.

Also the Vertex_displacement_mixer doesn't update in the ipr, need to click refresh every time.

Hey there!
I am so sorry - this totally slipped my mind...
If you're on discord I would highly recommend joining our octane discord and the houdini channel there, as the notifications etc here on the forums can be a bit iffy.
On the discord it's usually much easier to get quick response and you can even DM me if it's urgent

Anywho I checked your file, but unfortunately there were no textures included and there were some missing HDAs so I wasn't able to reproduce any crash.
You can use the "Archive Object" tool from the obj tab menu to create a shareable file setup that includes all references.

Or tools like odtools also have some features that can do this - but the above tool is included with Houdini.

And if to make sure any HDAs are included you can enable this setting in the asset manager:

I did a writeup on some common troubleshooting here:

In your case it might be worth trying step 3 - clearing the octane app data folders - and seeing if that helps any.

Good catch.
Looks like the Houdini plugin is actually updating but the values aren't reflected.
Just tested in octane standalone and same thing happens there so looks like a core bug - will share with core devs.
Thanks for reporting this!
