Fluid Performance: Primitive Colliders vs Mesh Colliders

[writer51]

Terrain colliders are about as fast as primitive colliders. This is because they're implemented as height maps, there's no need to collide directly with their geometry. 4 array reads and a bilinear interpolation is enough to get the distance from any particle to the terrain.

Thank you, this helps me a lot in planning ahead! It was also best case scenario for me.
