@GameMaster79 - With the release of 4.14, one of the major hurdles to making this system easily shareable has been overcome with the addition of PreSkinned vertex positions by default in the engine. Previously I was having to hack that into the usf files, which meant a full recompile of all materials, and was hard to convey how to do easily.
In addition to that, I got the blood mask + sphere mask operating together as they’re supposed to according to the white paper, though it still needs a bit of work for the offsets to be fully controllable (right now you can’t move the mask in the direction it’s projected in).
Now that it no longer requires changes to the engine level material shaders, I plan to release it as a pack, hopefully soon (need a bit of time to get the meshes done, as I’ll have to hire someone on for that).
