I’m encountering moving noise on shadowed surfaces in the 3rd person shooter template map (in 4.24.3 and 4.25.3). I work on a rather solid computer for Unreal as of lately:
AMD Ryzen 5 3600 (3.6 GHz base)
RTX 2070 Super
1 TB SSD
Gigabyte AMD B550 motherboard
32 GB DDR4 RAM (dual channel)
I’ve tried a ton of changes to Project Settings and lights. I’ve tried static, stationary, and movable directional and skylight. Various settings for those. The one thing I changed in the post process volume that removed most of the noise I’ve encountered (as there’s a couple other instances of fine-grain noise which were inside 3D models and on the surface of one of the starter materials). The moving noise is exactly that. It looks like a usual type of noise (splotchy, low-quality results of lighting) that’s moving in a sort of streaming fashion across surfaces that are shadowed. I tried a few different programs for recording a video of it, but all were too low-quality and slow in output to be useful. Tried turning off ray tracing, and starting a new project with ray tracing disabled, and it’s the same problem. Funny thing is, I didn’t encounter this moving noise on a laptop I was previously using. The laptop is a far lower spec computer than the one I’m getting the noise on (2.4 GHz dual core, 6 GB DDR3 RAM, integrated Intel graphics 5500U), and I never experienced it on there in 4.24.3. The noise primarily shows / occurs when I’m moving the camera around, whether it’s rotating it or otherwise.
Any questions and/or ideas to solve it?
