I’m trying to do a render using Pathtracing in UE 5.1 but is crashing in the first frame.
The video size is 1920x1080, If I do it at 1024 samples it works, but the image is too grainy. If I increase to 2048 the GPU rans out of memory and crashes. And the sequence is only 45 frames.
I made a render months ago with the same Level in UE 5.0 in 4K and worked perfectly, I don’t know if is an issue with the update to 5.1. And this scene was 300 frames.
Made more tests, the crash always happens when I use 2048 samples, doesn’t matter the size. I did the render in 960x540
Then I rendered the same scene in 4K with 1024 samples and doesn’t crash, so I think that for the moment to have working renders I have to render it twice the size of what I need.
