Could you please render 150 frames instead of just one frame? You’ll see the evaluation time go up to 1–2 minutes, and the RAM gets clogged when using tyFlow particles.

During our render with 20 GPUs, the time per frame increased from 2 minutes to 7 minutes (During 150 frame rendering), and about ...

Here's the scene


Hi Elvissuperstar007,
Thank you for the scene.
I tried repeating viewport rendering, closing viewport, changing some parameters, re-opening viewport, many times, but could not reproduce the crash..
What kind of editing do you usually do ? (eg material parameters ?, camera ...

Thank you for sparkles shader!

Hi neonZorglub,
1. Here is the scene for slow eval times with tyflow. When you open it just try to render fram 190-250 It gets very slow. (I think Render instances in tyflow mesh even is not working. It renders as copies using a lot of vram)
Someone had the same problem with tyflow https://render ...

I’ll have to write the post again. This build is better than the previous one — that one was constantly crashing. This one crashes after some time if I right-click in 3ds Max and open the Octane Render viewport. It has crashed 8 times since this morning. This has never happened before.


Hi ...

Hi neonZorglub,

Can you look into tyflow and slow eval times? Over 100,000 ty instanced little particles as low res spheres and eval times are 2-3 min per frame. But they are supposed to be instances.
Thank you


Hi coilbook,
Sure, I'll have a look.
Could you share a sample scene ?
That would ...

EDIT:
I have managed to reduce the error down to a single bitmap texture for debugging (however multple textures cause the render to not start, however not all of them)

See attached scene, I copied out a material from an old scene and on a new scene applied it to a plane.

To reproduce

3ds Max version supported: 2013 to 2026.

Changes of the 26.5 version, from 26.04

Updated to Octane 2026.2
Fixed crash with some textures
Added missing Image Tile Set texture
Fixed issue with tyFlow particle ID - added 'Birth Base ID'
Fixed issue with imager upsampler
Fixed issue with ...

PBR does not display textures — the model has UV mapping and a concrete texture, but the renderer does not see it.


Hi Elvissuperstar007,
Thanks for pointing this issue.
In fact, there are several PRB materials in 3dsMax, and Octane currently supports only the new OpenPBR material (available ...
