Trying to project a shape on a surface with multi-layers.
In a particle system, the particles will not move in relation to the layers. They will project a shape on the nearest surface.
Sometimes the shape is tilted, projecting on partially between two layers.
I setup each shape to project a center to a surface, and than get the neighbor points on that surface so I can create a temporary plane to project. But the vex I have is not efficient, so I would like to ask for an alternative.
