Hi! I have a problem regarding the collision using a ‘Line Trace By Channel’ or ‘Get Hit Result Under Cursor By Channel’. There is sometimes an offset with the collision. When i activate the Show Collision option it looks good.
I have the option ‘Complexe Trace’ on.
I use line trace to stick a spline along a mesh.
Yes he got collision, you can see it on the picture (i activated show collision). The purple squares show impact Point, collision work but there is an offset.
Another exemple without debug info and the mesh is hidden this time:
I would try just tracing from a stand alone blueprint to the mesh and move the blueprint around a lot to make sure your tracing works the way you think it should.
Apart from that, there can certainly be some gotchas to working with splines.
Ok i found the bug it’s probably a floating point error on collisions. It’s because I resized the mesh x100 after the import, the collisions are good if i scale before the import. It’s still weird that the ‘show collision’ option doesn’t show errors…
