Currently just SSao atm, why SSao? Filter-based ao doesn't really work with Z-Mimic O7 Lighting cause I got tired of trying to make ours work with this. But hey, we got directional lights now so that's cool. 🆑 @Zandario & @Lohikar add: SSzmimic add: O7 Lighting add: SSao del: SSopenspace tweak: Lights now can shine in angles between 0 and 180 /🆑 Co-authored-by: Lohikar <lohikar@protonmail.com>
