Hi is it possible to merge several blocking volumes ?
I want to constrain character movement along a winding road, what is the best way to do this via blocking volumes ?
The question is, in what way are you creating the road? Are you using spline tool? Or are you creating your custom mesh in 3d package?
I just posted a minute ago the little hint for the colliders here: Issue importing UCX collisions - Platform & Builds - Epic Developer Community Forums
If you are using spline tool, you could bend by spline both, the rendereable mesh and also collider.
Actually I never used the spline tool yet, so maybe someone has a better way of doing that, or could confirm if that will work?
If you ask me, you need no extra blocking volumes.
Set up a splineroad and add two collisionborders to the splinemesh component, where you want them. You can even place a cube there(with collision), make it invisible.
This is cool https://www.youtube.com/watch?v=3GIcFrR-bJk&list=PLHadbgEqCTxDgj-RwPQGkaUypb05NJYN6
Exactly, best would be to make few UCX colliders, so this way you wouldn’t have to bother to create any extra spline components in construction script, other than for rendereable mesh. In this video you can clearly see that colliders are bending all together with the mesh: UE4 Tutorial: Add spline-meshes procedurally - YouTube
Only thing in consideration is to make edges of colliders and mesh as parallel-y possible, so they bend in equal manner.
Cheers.
