OctaneRender® 2026.1 Alpha 1

That are some very nice features!

"Neural Rendering Modules and Nodes (experimental): Launch ML and Neural Filters locally or through the Render Network with integrated local and remote neural rendering within the Octane Node Graph." Where are those? I don't see them in 2026.1 Alpha 1.

Nice! I just tested the new displacement feature on an RTX 4090, one 8k material from Quixel on a simple imported plane and it completely locks up on anything over a 1024x1024 displacement texture, is that expected currently? The viewport becomes unusable and renders 1 sample every 30+ seconds or more. Memory usage is fine, only using 13gb according to GPUZ

Same issue on my system. The displacement is usable on 1k textures. Everything above starts to slow down viewport considerably.
Old displacement system is really smooth with 8k textures.

Moreover the displacement still breaks the geometry apart.

The new Texture Displacement definitely needs to be optimized, that's a known.

"Octane's texture displacement system is being given a complete overhaul. The quality of the displaced surface, especially with high frequency input data has been much improved. It is also now possible to use OSL textures directly with texture displacement.

The implementation in Octane still has several issues left to solve, including feature interoperability, the Metal implementation, UV mapping, and most importantly, there has been no performance optimizations yet. VRAM consumption in this alpha is far heavier than it will be with the next set of changes. Please also note that you must use a Mesh UV projection in the input texture, at the moment. We are planning for this requirement to be lifted when we get to stable."

About the "broken" geo, you need to specify a proper smoothing angle in the
Settings of the Geometry file node (set the Max Smoothing angle to 90).

Also, I've noticed that using the Cinema 4D noise makes it way faster than using the "standard" Noise Texture.

I think that a global setting to set the max res for all displacement nodes in the scene would be very useful, by the way.

Yes, it is expected (from the main post):

It's still in development, but very impressive already:

About the "broken" geo, you need to specify a proper smoothing angle in the
Settings of the Geometry file node (set the Max Smoothing angle to 90).

No matter what smoothing mode or angle you apply new displacement explodes the box geometry.
On the other hand old texture displacement works properly.

Here is the example file. Is there anything wrong in this setup?

It worked for me. Downloading your scene now!

You forgot to include the fbx and the image.

That's what you need to do:

With obj file it works properly.
Try with Octane Geometry primitive box or the fbx file exported straight from Blender (attached).
