For 2 days im trying to find a way to get hair to react to an animated vertex map.
Very simple setup:
Cube with vertex map (with Spherical field in one corner and a Freeze set to grow with MAX as blending mode) -> Add hair to the Cube.
In the hair material i try to control either Length, Scale or Density with the Vertex map by clicking the Texture dropdown: Effects -> Vertex Map and inserting the Tag.
Nothing happens..
I also tried doing the last step in the hair object -> Guides (and Hairs) -> Growth -> Density.
Still nothing.
Did i do something wrong or should this have worked? If so, can someone confirm pls?
