Please see the image. I have the trail renderer attached to my player. That is the trail from the player as he jumps from platform to platform. I circled the parts in question. What is causing this to happen?
Too many points too close together in your trail, can cause the geometry extrusion logic to get confused. We are looking at improving this (and have bugs logged for it), but currently, a workaround would be to increase the Minimum Vertex Distance.
