So i’ve almost finished building something, and for some reason there is a big, tilted surface, that is invisible and has collision, and I can seems to figure out what it is and delete it/change it’s collision.
What can I do?
We’ve also encountered this problem in 4.18.2. We’ve searched through the World Outliner but haven’t found any guilty objects. Does anyone have any suggestions for this issue?
After a process of elimination, we discovered that the invisible mesh was attached to a combined static mesh actor. Removing and replacing this (a bunch of large rocks) eliminated the large invisible collision and nav mesh.
I’m not sure that this error with the combined static mesh actor did not exist in 4.17, but 4.18 broke a lot of LODS, so I suspect that it is the culprit.
Thank you very much! I wasted a looot of time trying to figure out what’s going on.
Version 4.24, same problem.
This issue happened to me, and it may indicate that one of your assets has an incorrect scale, such as (-1, -1, 0).
Symptoms
Characters and projectiles collide with an invisible wall. Inspecting the scene using the Show Collision menu reveals no visible collision for any asset.
Problem
One of the meshes had an incorrect scale. This was evident in the logs:
LogPhysics: Warning: Scale for /Temp/Game/Maps/MAP_ShiverbonesPeak/MAP_ShiverbonesPeak_LevelInstance_f4cbf75f082ce2e9_0.MAP_ShiverbonesPeak:PersistentLevel.StaticMeshActor_5.StaticMeshComponent0 has a component set to zero, which will result in a bad body instance. Scale:X=-1.000 Y=-1.000 Z=0.000
LogPhysics: Warning: Scale for
Solution
I resolved the issue by resetting the scale of the problematic mesh.
Note: I modified the projectile code to display the colliding actor, which significantly helped me track down the problem.
