GPU sample limit

[soviet_post]

Hi,

How do I limit amount of samples per frame using GPU? Can't find Samples Limit in Houdini, here is a screenshot from 3ds max.
Already emailed to support but hoping for a community wisdom in case if I just simply overlooked the settings.


Thanks a lot

Hi soviet_post

Samples Limit parameter is specific to the GPU UI in 3Ds Max, this is how it is calculated internally
Max Subdivs = square root of samples limit + 1
If you use around 70 max Subdivs in Houdini, you get an identical result to 5000 Samples limit in 3Ds Max.. In reality you only need like 50 Max Subdivs for V-Ray GPU, keep in mind that Max Subdivs has a big impact on performance
And you can set the min Subdivs to 8 in houdini, which is what Max uses by default

We are going to change the GPU UI in Houdini soon to be similar

Best,
Muhammed
