Hi,
There is a bug / unexpected behaviour happening with splines. They do not follow the static mesh’s collision pre-sets and defaults to Block All.
This bug also affects trace channels and tracing behaviour. But for proof of concept the reproductions steps use NoCollision preset.
Reproduction Steps
- In a blank project, select a cube and change the collision pre-set to No Collision
- Place a cube in the map and make a spine on a landscape as well using the same cube. Enable collision in the spline segment menu
- You will notice that you can walk through the placed cube but the collision is turned back on, on the spline cubes
Cheers
