Not for GPU, no. Not yet. :/

Same for me.

I mentioned this way back in the thread - it's really cramping my workflow...

I am bugging the devs about it, should hopefully be fixed soon. :/

I'm curious about "Measured BRDF". Can someone explain this, give some nice measured data? :D

well its measured Data with colour & reflectance informations saved per wavelength.
You can try all these here: http://people.csail.mit.edu/wojciech/BR ... ase/brdfs/

But keep in mind, that this database is not usable for commercial work!

Also afaik, BRDFs are have no or poor importance sampling atm, so very reflective materials can cause Fireflies and render slow!

Wow, how amazing is that! I tried the nylon from the database you linked to. Instant results! Now, if only I could modify some of those data, to suite my colouring needs! :D

P.S
Very low sampling importance, indeed!

This is afaik the main problem about such data, you can't edit it... at least not that I know of, sure google knows more then me -.-'

Afaik its just a first rough implementation to read such data and integrate it into Indigo, we'll see about how it will progress until v4 gets stable...

It's a great addition, really looking forward to see where it will lead us.

Indeed! I even find red velvet but sadly it wasn't in a format Indigo could read.

Yeah, like a complete new step towards the realism. And with GPU, it's gonna rock. Now, if I could only get my hands on some "lab" where I could tweak exponent, IORs, coloring, based on a template for example silk, plastic, nylon, it would be phenomenal. Imagine that, creating and developing your own materials, like if you were in a lab of some sort. We could call this part of Indigo....Labigo! :D

I second the Labigo ® ! :D

As for the BRDF....every material is data and every data is editable just need to find the tools to do so.

A test.

Overnight rendering!

No banana for scale? o.O
:D

It seems that when checking all boxes to render on CPU's and GPU's that the renders tend to be slower than just GPU. I suspect that when the CPU is also selected that at least 1 thread should be disabled for each GPU in the system, this way the CPU will be able to keep up with the GPU's. I'd wager we could see some nice speed improvements this way and really speed up systems that only have an Intel or AMD chips with integrated graphics.
