So, I´ve spent all day today troubleshooting an older project I needed to update and render fresh….
Everything worked fine until I got to rendering.
I had set up a couple renderpasss sequences and one needed toi render various objects into various additional layers in a multilayer EXR.
This had worked fine before, but now it kept crashing.
After several hours trying to pin point the problem, I arrived at the render layers being the culprit.
Scene is quite heavy with tons of foliage, but rendered in 10 mins for 3500 frames in 4k on my 3090 before, using DLAA.
Also tried normal antialiasing, but was way slower and also crashed when I enabled layers.
Now, I was able to render the main beauty pass, but still need those layers, setting up manual overrides for dozens of objects on those layers is a last resort, so I wanted to know if anybody else experienced crashes or physical ram maxing out when rendering with layers?
Can´t reproduce it on a very basic scene, there is still considerable slowdown, but it renders without crashing.
Definitely worked a few Unreal versions back (maybe 5.2/5.3) and I don´t think I changed anything so radical from the old project…
