Hello, let me cut to the point please. )

With the recent release of 17.5 version, i am wondering:

1) Are volumes automatically accelerated in the viewport, or do i need to do some setup for it to be enabled (still enable OpenCL for volumes?) (they say volumes are 3-4 times faster now?)

2) Is the same with principled shader, or do i need to run some setup to enable it?


Finally, are these features only for Houdini Core and FX or for Appreantice version also?

Thank you very much.

Really noone knows? It's not like i am asking random questions .
I've looked for the solution but it's not a clear picture to me.
I think it's a simple question.
Thanks

Viewport volume lighting is accelerated in 17.5, you don't need to do anything to benefit. (It is the same in all editions of Houdini)

Volume simulation/computation remains unchanged from before, (OpenCL in DOPs, VEX in SOPs, etc)

Thanks.
