Greetings @HyperspaceMadness,
You probably know this already but I still just wanted to share that once the hsm-crt-guest-advance.slangp pass is replaced by one of the hsm-crt-guest-advance-NTSC shader passes in one of the base presets in which the NTSC Filtering controls are not working properly, the NTSC Filtering Section controls begin to work as expected and shader presets which used them look as expected again.
