When I try to render an easy scene in UE5.4.2, which is containing almost nothing but 11 MetaHumans, the MRQ crashes with two pop-ups: GPU out of memory AND failed to launch zen server storage.
When I try to render the scene with only one MetaHuman on LOD 8, the rendering works fine but the process gets stuck while exporting. The rendering process lastet 1 hour, the exporting process is already lasting 3 hours. What should I do to resolve these problems?
My graphics card is an RTX 2080
It sounds like you are running out of memory. When you are rendering have you had a look at your task manager to see if you card is topping out?
Yeah, the memory quickly rises to 95-100%, then the crash occurs
If your render is taking that long, I’m guessing you are path tracing? If that is the case, try only lowering the number of samples you have set in Anti Aliasing in the MRQ settings until you no longer run out of memory. I’ve found setting spatial samples too high can cause memory issues. Find the balance between the number of samples and the denoiser that produce an acceptable quality.
What other MRQ settings do you have active in your render? Are you super sampling (over 100%)?
