Sequender Rendering 8K

Hello, did anyone here try to render 8K exr sequences from UE4 using Sequencer? I’ve been trying to do this and weird artifacts keep coming up randomly.

I’m doing this because UE4’s super sampling doesn’t work very well and TAA doesn’t work on the render passes…

I have the same problem… any suggestions ?

Might have an issue with GPU memory at that point

same here, would love to see some suggestions.
