ok, so according to the dll supplied with houdini it is 2.2.1. What I tried now was to get the latest compiled version (for windows) and just copied it over the existing dll in houdini. Not only does that work and also seem to yield better results, now the gpu acceleration works, too!!! I think this is due to the fact the OIDN version supplied with houdini misses OpenImageDenoise_device_cuda.dll.

This fixed the ai denoiser node that, by default, does not work and does not show the optix denoiser. Thx!

Sound like the DCC you would like to use it's Softimage Xsi.
It has the hi-level modelling tool easy yo use, and a stack for non destructive tools and operation (at least untill a certain level).

It's a pity it's a dead program now

I'm reading this and I'm a little confused. I am trying to render a spreading fire in Karma XBU and it shows up in the Karama Viewer but *not* in the render. I did find the simple pyro shelf and tried the spreading fire...I can see it in the viewport...I went through the instructions in the recent hive video...I could see it in the regular karma but not the gpu based version

First thing to do, click on convert to vdb must be on in the pyro solver. You’ll start to see a grey volumes

Then you have to change material to the new xpu pyro shader, you’ll loose connection to viewport and pyro shading parameter but you can quickly resemble the original one.

It’s not very well explained nowhere in the docs, I found it in a video from side fx on you tube.

I really don't get it... i'm not the only one with this problem, but i'm the only one that can't make it work with the Convert to vdb option?

edit:
ok i got it know, i need to use the xpu pyro preview. is there a way to link the pyro solver to the xpu pyro marerial?
the regular pyro shader is't a little bit different... i can't find the gradient for example...

I'm a total noob to pyro rendering.

Convert to vdb

Hi,
i'm stuck rendering volume with xpu.... does it work in apprentiece version?
Do i need some specific driver?
When i turn to xpu, the pyro renders only gray volume...
