using this postprocess material works as a replacement for r.ToneMapper.Sharpen, and I keep the postprocess material’s sharpen param as 0.4 if I remember correctly
as for the other values, I find it good if I use TemporalAASamples as 4 and TemporalAACurrentFrameWeight between 0.05 and 0.1 depending on the project
as usual I still find the temporal reprojection to be lacking (causing ghosts), and for me changing the CurrentFrameWeight based on the camera location delta (vs the prev frame) still is the most decent solution for this. I added that into a project by modifying the engine source but I think I might be able to do it now just by modifying the engine shaders. I’ll get to try it eventually
