It'd be nice if they ignored ANY animated flat, just like decals don't appear on animated walls. Blood can't really stay still on surface that moves after all. Don't know if that's possible though.
NGM v1.0 added support for liquid effects, so blood that falls on liquid will have different, special effects. It respects liquids defined through TERRAIN as well as 3D floor liquids. I removed that custom liquid lump because it's not needed; it should be handled through TERRAIN.
For vanilla Doom and Doom 2, you can use
viewtopic.php?f=37&t=35547 that adds TERRAIN liquid definitions. Heretic, Hexen and Strife already have liquid definitions in their IWADs if I'm not mistaken. For other mods and map packs, you'd have to make your own. Look at Enjay's mod I linked to, or
https://zdoom.org/wiki/TERRAIN for info on how to make your own TERRAIN lumps. When a texture is defined as TERRAIN liquid, NGM will take care of the rest.
