Additional fix for indirect capsule shadows detected by devs in editor Indirect capsule shadows overwrite the result of the screen grid DFAO, which results in two issues. The first is that the indirect capsule shadows changes the size of the BentNormalAOTexture, so the PIE renderer samples the texture at incorrect UV coordinates. The second is that each view iteration will overwrite the BentNormalAOTexture, so the multiview result is the last per-view texture. The solution is to also call this function per-view. The previous changes include creating a per-view bent normal texture before copying back into an atlased texture. This involves a set of changes for UV sampling (e.g. in UpsampleDFAO) and setting up the culling properly in BuildTileCones. #rb tiago.costa [CL 26263184 by jeffrey liu in ue5-main branch]
