3.3 sampler

[tim_harding]

I'm quite excited to try the VBAS method of sampling now available in Max. I've always used the Grant Warwick workflow for setting up sampling parameters, which works, but it takes time to go through materials and lights one by one. The new sampler looks super slick, I'll be curious to see how much custom setup it can alleviate while also speeding up my renders. Any news on when we can expect to see some of these features make their way into Vray for Modo?

The Variance-based adaptive sampler (VBAS) has been in the nightly builds for a long time. It is not part of the official 3.01.01 build though.
Everyone can request access to the nightly builds by sending an e-mail to support [at] chaosgroup [dot] com.

Yup its been there for awhile.

Just make sure that use local subdivs is off in the DMC sampler rollout. It might be by default off already though.

I've just updated to the latest nightly build but can't see an option for VBAS in the sampler type dropdown.

Do I have to enable it somewhere?

[vladimir.nedev]

It's not a new sampler type, it's a new noise estimation for the adaptive and progressive samplers.

So 'Default' is Variance-based adaptive sampler and 'Legacy' is the 3.2 behavior?

Yes, we will be removing the option at some point.
