描述
This GPU Niagara System uses Distance Fields to create dynamically moving and animated (via shader vertex offsets) StaticMesh bugs that snap to walls and objects with a possibility to be attracted or repulsed.
Multiple parameters exposed that control speed, repulsion strength, randomness, number of bugs.
The attraction/repulsion location and radius are controlled via Niagara Parameter Collection from any actor.
Distance Fields must be enabled in the game for this effect to work!
Being Distance Field based there are issues with single-sided plane meshes. To avoid that, separate mesh with thickness can be used for Distance Fields
