Hi all,
Currently trying to render a scene using path tracer in MRQ and it seems to be taking a lifetime.
I’m fairly new to UE5 but it seems mental long as I don’t think it’s a crazy complicated scene.
It’s essentially a landscape with instanced foliage, buildings with emissive materials lighting up the rooms inside and frosted glass.
With 800 samples per pixel, viewport path tracing takes about 20s to gather a frame that would be perfectly fine for a final render… Then MRQ with 1 spatial and 800 temporal samples takes about 12 minutes for one frame.
I’m sure I’m missing something very obvious but I would love to know why it’s so much longer and how I could get the final render closer to viewport times.
Any other general advice for speeding up path traced renders would be greatly appreciated. Struggling to find many tutorials for optimisation
Frame size is 3076x1050 (this is half res of my desired output as well which makes it even more annoying)
Running RTX 3090
Please help
