[FYI] Tiantian.Xie Original CL Desc ----------------------------------------------------------------- Fix the screen space denoiser causing ray traced transmission leakage. * Add another bilaterial filtering weights specific to transmission for Screen space ray traced shadow denoising. So shadows on subsurface profile will behave the same to other material, and the transmission will be filtered separately. The spatial filtering weight will be set to 0 if the reference and the neighbor pixels are not all subsurface profile. * Suggest: Increase r.Shadow.Denoiser.PreConvolution to 2 to remove the border line neglectable transmission artifact due to temporal accumulation. #jira UE-206157 #ushell-cherrypick of 31215240 by Tiantian.Xie [CL 31502825 by tiantian xie in ue5-main branch]
