Click on the demo link on the home menu and get ready to play with fire. 8-)

Awesome!!! :D It appears to be fast too, even for an older GPU (K520).

Seems bussy ? I'm looking at "Starting new server" for last 7 minutes, still nothing ?

I have a question: every volumetric effect is in .vdb format, what is that? Also, if you zoom closely, you can see the voxels, is there gonna be a detail setting?

Rikk, the VDB format is part of an SDK released by Dreamworks which is a suite of tools for loading and manipulating volumetric datasets. It is supported by a number of products for exporting datasets, and takes up little room for the amount of information it is capable of representing.

We are currently working on improving interpolation to remove visible artefacts when zooming in. In some cases, this is a limitation of the dataset generated (perhaps not high quality), and in other situations, it is caused by the Volume step length in kernel parameters being too large.

Thank you mist for the explanation. 8-)
Is there any other v3 new feature in this buld, beside the volumetrics?

Animated image textures, environment medium, raw/filter render passes, better film better management (i.e. less vram usage) and the export part of the PS plugin (you need the PS plugin for the other part).

cheers,
Thomas

mmm, I can't find the environment medium, and the raw render passes seems to not do anything... How do you use them? :geek:
Also, it crashed while I was zooming in and out in the viewport, but I guess this is expected as it's a beta... ;)

That looks great. How do we know how many cudas it's using so that I can compare it to my setup?

It's a K520 so it gets roughly 40 on the OctaneBench score.
