Just pushed a small but convenient extension for HBAO to the main branch. If HBAO+ is enabled via r.HBAO.Enable, the builtin SSAO is now disabled internally and doesn’t render anymore. So no more problems with SSAO overwriting HBAO, no more manual disabling of SSAO in postprocessing volumes etc. HBAO always takes precendence now.
Let me know if you find anything fishy related to that.
EDIT: And almost forgot: WaveWorks integration is now also part of the 4.20.3 main branch.
