vray material sss

[ronald_a]

Hi,

we have been using the new sss mode on a couple of projects lately. While it needed some time to get used to, the results are great.

There are a couple of things I would like to point out that could be improved:

- Speed: while it might not be a fair comparison, coming from al surface, the speedhit is pretty massive (we have seen 3x rendertimes depending on the scenario). So whatever can be done here would be great.
- are there plans to introduce a phase to the scattering?
- could the ui be optimized: it is strange to setup sss on two different tabs (in refraction and in translucenscy). Also some of the parameter names are confusing. Fog for example should be Scatter Radius (when sss is enabled). Also some of the parameter (bFws/Back coeff, Light Mult, Scatter Coeff, Max Thickess) do nothing and should be removed.
- changing the sss type while in ipr does yield wrong results. ipr must be restarted to get the expected result.

Hello ronald_a ,you are right. The UI of V-Ray Material need some improvements. We are now working on it.

chakarov the updated ui works nicely. Thanks for putting that in so quickly.

Still I need to push on the painpoint of speed. Are there any plans to make this render faster? I am more than happy to share a production scene with you to take a look at.
