Kvant/SprayMV

SprayMV is a specialized version of Spray that supports motion vector generation.

The original version of Spray doesn't support motion vectors, and thus it can't be used well with post-processing effects that requires motion vectors (e.g. motion blur). SprayMV generates exact per-pixel motion vectors from each individual particles. This allows depicting motion of a complex particle system in a very natural way.

System Requirements

  • Unity 5.4 or later

Caution

This is only a sort of quick and dirty hack -- implemented in a weird way for some reasons. I made this "hack" because Graphics.DrawMesh doesn't support motion vector generation (the original Spray is heavily dependent on it). It should be redesigned when motion vector support is added to Graphics.DrawMesh. Until then, this can be used as a workaround.
