Dear friends,

one of the things most requested after publishing Presto v1.2 was sub-surface scattering (SSS) and volumetrics support.

To be honest, I had this as a relatively low priority for the things to be added in Presto. But I was persuaded at the end,
that this is a first class feature that we should not be missing.

As you know, Thea unbiased core (TR1/TR2) gives volumetrics and SSS of highest accuracy. Initially, we thought of
making use some approximation models for SSS for Presto, so that to deliver highest efficiency. But at the end, due to Presto
being a progressive engine, and having already the experience to deliver the real SSS, we decided that realism is all that
matters. And we were happy to find out that Presto delivers this realism very very fast.

Below, you can see some samples of scenery with one or more SSS materials. And we are talking about renders converged quickly,
with the real thing, real SSS without approximations. The results should speak for themselves.

Best wishes

Maybe I'll start using SSS after 1.3! :shock:

Simply Awesome! I think adding these features to Presto now, rather than later, was a good decision.
Best Regards,

This looks great.

What I miss for all tech previews is hardware used, resolution and render time.
It would be great if you added a render stamp feature in Thea so users can easily add it to their renders.

I agree, Jan, and I appreciate your point of view...
However, I don't think it will make much sense, since more optimizations are being made while in Beta test phase...
I.e. the above renders could have taken 3 hours, but when the final product gets released the optimization will mean that the render can be done in only 2 hours... :)

I simply meant that it would be a good thing to have for the future. Especially if someone wants to compare Thea with other render engines.

I rendered those images on a i7 3930k 3.2 GHz + GTX 680 2GB ... and the longest render took 25 minutes and the shortest 3 minutes :)
