Changes the filtering for cutscenes. By default, ANMs are unfiltered and IVFs filtered regardless of the filtering option in the menu. Use “texturefilter” to use the same filtering as textures, “forcenofilter” to never use filtering and “forcefilter” to always use filtering.
cutscene <path> { texturefilter }
Patch from Fox.
