Hi everyone,
I am having major issues on an animation where by I am getting these weird boxes of high frequency noise. It's happening towards the end of the render, by that I mean when the noise level approaches/drops to the specified amount (first I had it at 2% and then I raised it to 4%)
Its super frustrating because it makes no sense for it to happen, I can understand poor materials or bad lighting to make excessively noisey renders but for the noise to actually emerge towards the lower noise limit is really strange. Also the box of noise jumps around the same area but its not consistent in its placement in that area, if that makes sense?!
I've obviously had a quick look already and I've tried the following.
1. Removed the bloom and Glare from the result (I saw a post about this possibly causing this issue)
2. Increased the noise limit from 2% to 4% I had thought it was caused by some odd over sampling bug.... it looked like it did work but this noise happens on random frames, its not consistent.
3. Tried turning denoising on and off.
4. Changed lighting strengths, removed any outside emissive backplates.
5. Simplified the material, no textures, no crazy high reflection amounts etc
Any suggestions would be welcome. The Scene is lit with a basic corona sun and sky. No overlapping geometry, no weird wholes in any of the meshes etc
