Max sample level set to 0, but where?

[smbell]

So i'm seeing the new "Max sample level set to 0 - rendering could take longer than expected. Consider setting a value to decrease the render time (i.e. 10000)" error, but for the life of me, I can't find a "Max sample level" to set.

I've got my Max render time at 0 and my Max paths at 1000 and Max noise at 0.01. I just don't see a "Max sample level" anywhere, I'm sure I'm overlooking it somewhere.

Does this happen when you are rendering in IPR?

This warning should concern you only if you are rendering Production with GPU. You can ignore it when rendering in IPR.

[smbell]

ah, yeah. I was using IPR.

Thanks.

I saw these warning on my render production with GPU. It's something wrong?Can I not ender on production with GPU or something similar? Any advice is welcome.

0 for max samples means that you're allowing V-Ray to make infinite amount of samples. In this case, some other cutoff criterion can be reached (max time or max noise).
The warning you're seeing means that 0 for max samples is not really recommended, unless you know what you're doing, of course.
So for an IPR session, 0 practially makes sense and you can safely ignore the warning (we'll probably do something about hiding it).
For a production render with GPU, however, 0 for max samples (max subdivs) only makes sense if you're using a noise threshold above 0 , and/or max time above zero. If that's your case, ignore the warning. If not - then follow what the warning advises.
In any case, we probably need a better warning or a better case to print it.
