That are some very nice features!

Maybe I mist it in a previous release but are meshlets still coming? or already there?

Arnold has the possibility to disable diffuse reflection of an object (specular reflection, diffuse transmission and specular transmission are also options that can be turned off). I would die to get such features in Octane. Is this something that could be added?

Looks like the ray switch 'diffuse' function does not work properly any more. If I try this old orbx file it does not look that same as milanm example.

file does not work ...

If I render my groom (curves) and I disable shadow viibilty, my render becomes 35 times slower. (I render with path tracing kernel and alpha shadows on)

I did a test on my current scene:

low resolution 4000 samples

14 sec with Spectral AI Denoise
30 sec without Spectral AI Denoise

full hd 4000 samples

78 sec with Spectral AI Denoise
69 sec without Spectral AI Denoise

On a 4090 with octane 2022.1.1

They are working on streaming geometry and textures from an ssd (direct storage). I think that will be in the next big version of octane.

In the shadow pass, I see objects that aren't supposed to cast shadows doing so.
Despite having turned off the general visibility, camera visibility and shadow visibility in the object layer, the shadows still appear in the shadow pass.

I cannot reproduce this. Can you provide a simplified scene ...

@abstrax If you change the framerate of the attached orbx file to 250 and scrub the timeline, you can see that the point cache cubes do actually posses al the substep information.

On this related note I have another issue: when setting the fps in a file via lua script:
