millions of instances with motion blur

Hi,
I'm trying to render sand grains, approx 20 million particles, rendered as instances of 4 different grain geometry types. Although the scene processing time can be a couple of minutes, it does manage to render using about 13gb of vram. But if I turn on motion blur, after a longer processing time ...

multistep sub frame deformation motion blur

Hi,

I have an object that is deforming quickly and when I render with motion blur I get linear blur streaks even though there is continuous animation arcs data. Is this supported by Octane? I'm unable to find any relevant information.

Thanks

Re: projection color to uvw not working with bump

Can you suggest a workaround for this? I've tried using the tool baked image node but that didn't work either.

Different issue I've also noticed is that bump textures from uv2 create strange artifacts on the uv island boundaries but when swapping uv2 to uv, it works fine.

Thanks

Re: projection color to uvw not working with bump

I don't know. I thought since it's actually generating projection coordinates then it should work just like world space coords work with noise and bump?

projection color to uvw not working with bump

Hi,

When using projection color to uvw connected to a procedural noise it works fine when the output is plugged into albedo, but when connected to bump, it doesn't do anything.

Attaching a sample scene.
Thanks

displacement map clipping

Hi,
I'm getting artifacts with displacements maps. I've checked in photoshop that there is detail in the full range yet in Octane it seems to be ignoring certain values.
I'm using the Displacement node and not Vertex Displacement (VD does work correctly but is slower to render).

I'm on Houdini 19 ...

sky transform

Hi,
Is there any way to transform (more specifically rotate) the environment sky models? Not just about the North offset but in any axis?
Also it seems like the ground start and blend angles don't do anything.
I'm trying to artificially lower the horizon of the physical sky.

Thanks
Yaniv
