It seems impossible to ignore lights for objects or objects for lights in Octane. It would be very needed for special effects so is this missing feature, bug or is it somehow impossible in Octane?

Any ideas?

Sorry, currently light exclusion is not possible in Octane. You can use the unseen by camera and cast shadows flags in the objects, but all other exclusion options are not available in Octane yet.

Ok, that's what I thought, otherwise you had already implemented that feature in the plugin.
No problem, I solved the related issue other way, thanks to Octane's emission nodes

The daily build has been updated. The current version is the 2.15.1
The OSX release will be available tomorrow.

WOW again very impressive list of improvements, thank you very much

when I uncheck importance sampling I get a very small HDRI background image influence to radiosity, the image looks very different.

Indeed.. nice update Juanjo. I noticed with this build and the one prior, the GPU usage ratios when using priority settings are much better now. In previous builds even when set to 'low' my gpu was still around 75% and slowed my video performance down while rendering. Now it's something like: Low/Med/High --> 50%/65%/98% (big jump from medium to high) Much better ratios tho, nice work.

Also I must add that overall the latest build, and refinements to the octane core are simply awesome. The kernel additions ie: coherent mode, gi clamp, highlight compression can be tweaked to REALLY speed things up. I'm really loving it.

p.s. in the release update documentation you suggested no use in going higher than 1 for coherent ratio... I'm usually using a ratio of 25-50!

I need to test it, but anyway, why are you disabling importance sampling? ... I think that this switch should be deprecated.

The new "UV map for the FiberFX hair systems without UV data" has really helped us out on our project. Our character's beard and hair look great now. Thanks so much!
