3ds max very slow to recover after rendering?

V-Ray for 3ds Max V-Ray for 3ds Max :: Issues

Hi,

I’m not sure this is a VRay issue or not.
On some scenes it happens that after rendering (especially when rendeirng particles) max takes its time to recover. Even if the rendeirng takes like 2 seconds, I will have to wait at least 15-30 seconds until max responds again.

Which max and vray version is this?
There was an issue a while back with Nitrous, and in viewport properties if you just untick “Improve Quality Progressively” under Display Performance, it helped a LOT. But as I say that was a while back, can’t remember the max and vray versions now

Max 2014 and VRay 3.0. I will try that. Thanks :slight_smile:

It could also be the renders you are saving. If they are very big and you have many layers they will take their time to release max…

I don’t save them at the moment, neither in the History nor on disk. I tried the Nitrous thing and it doesn’t make a (notable) difference.

Are you rendering from a “shaded” viewport?
If so go back to wireframe before you render and you will notice a massive difference :slight_smile:

That actually seems to help! I’m not sure of the time factor it gets faster since my scene got heavy stuff also, but Thanks!

I had a similar-sounding problem that seems to have to do with Nitrous re-initializing materials and maps after a render.

Save your scene, then try switching to ‘Shaded materials without maps’ in the viewport shading menu. Totally fixed the problem for me, but if you switch back to ‘Realistic materials with maps’ it’ll enable the display of every map in your scene no matter how it was set up previously, hence saving your scene first and proceeding with caution. Max might hang for a while as the materials/maps get swapped.

Hope this helps,

I had a similar issue using Embree with static geometry when my RAM amount was too high. When I left 3.2 GB or so for the OS, the problem seemed better.

Hi, thanks for your reply. My system has 64 GB of RAM and the rendering doesn’t get over 20GB (My dynamic memory limit it set at somewhere around 55 GB)

Would it be possible to send us a sample scene and inform us in advance how much time it takes until Max becomes responsive after the render ends?
What is the exact Vray 3.xx.xx version?

Hi,

Will do. The next time it happens I’ll remember the time and send it to you. Propably within the next few weeks.
