I think it should be a high priority for Epic to fix the issue with raytracing + foliage + WPO. It’s currently impossible to get good looking raytraced shadows with foliage. If it would at least be possible to just let foliage use CSM and everything else RT shadows, then that would also be a fine solution, but it seems to be either “everything uses RT shadows”, or “nothing uses RT shadows”, and that means any scene that has any WPO foliage just can not use RT shadows at all. I would be happy with keeping foliage in CSM, and let all the rest use RT shadows.
