Hey Bikram,

I wonder if we're talking about different things here. I have attached another screenshot.

Something is happening between the output from Octane and how that image is interpreted in the Solaris viewport. The input texture is ACEScg. It's tagged as ACEScg. Nuke displays this as ...

Hi Master_39,

Thank you for the report.
Yes, we can replicate the slow particles and reported to our developer to investigate.
The denoiser seems to work on our side. Maybe the Denoiser is not enabled in the Device settings.

Hi,

I’d also like to report the following issues in Octane Solaris for Houdini.

- Particles are still rendered as instanced sphere meshes instead of true sphere particles, making renders extremely heavy and unusable with high particle counts.
- Denoiser still does not work. Even after ...

Specifically:

Enabling ACES Tonemapping in the Octane Camera = Imager produces no visible effect.

The Denoiser controls in the Camera Imager also seem ...

Hi,

I’m using OctaneRender 2026 for Houdini and I noticed a difference between the standard Octane plugin at Object/SOP level and the Solaris (LOPs / USD) integration.

In the regular Octane plugin, I can use the new OpenPBR Surface and Realistic Lenses. However, when working in Solaris, these are ...
