I had this problem in a complex scene, then created a simple scene to see if it was something complex was causing it.
Extreme memory usage as shown in attachment.
I downgraded to latest available 4.1 update 1.2 in download section and the problem went away.
The scene is very basic. Cylinder on plane (with shadow catcher). 1 Area light. 1 HDRI. Vraymaterials have no maps
Is this a stable nightly?
Yes, and this is on GPU by the way
Doesn’t happen here. Please send me the scene.
Actually more problems:
Using Vray GPU BUCKET rendering
It happens in every scene. Even a simple scene with a plane, cylinder, and area light.
Tried different nvidia drivers, different versions of max 2019, 2020.
Renders literally like 5 times slower. Freezes max when hitting stop/cancel. High memory usage
These problems all go away when moving back to update 1. Update 2 is completely not usable for me
You mean that particular nightly build is not usable for you. That’s not Update 2. If you don’t need to use nightlies, please stick to the official builds.
Anyway that was a regression that lived only in the nightlies and there will be a new fixed build in the next few days.
Hear hear.
Access to nightlies is risky, know what you (want to) get into.
Most of all, it’s *not* for public discussion, under any circumstance.
What goes on in the nightlies, stays in the nightlies. ^^
I just had concerns about the latest nvidia security problem and wanted to use the latest version to be the most compatible (asked about that in a different thread). I only mentioned this because it was under the stable section. Is is better to do that in the support email then?
@_Lele yea I know, I wouldn’t dare mention a feature or anything like that. I’ll stick to emails to be safer then with nightly stuff
Thanks guys
Yes!
Those are preferred, and work a treat, while not risking to scare the more general public (more than revealing some secret).
