We have built a mountainous terrain in our game with several angles too steep to climb (often you slide down the side) but we’ve run into a snag with the collision. We consistently fall through the terrain when falling. Even just creating terrain with the UE4 toolkits and the 3rd person blueprint template you can walk up to the steeper hills and jump against them until you eventually clip through it and fall.
I’ve created several levels with multiple projects and UE4 versions(4.0.2, 4.1.0, 4.1.1) and this is consistent across them all. I tried adjusting the character capsule larger and smaller and playing with the terrain collision thickness property but nothing seems to help. Any suggestions?
I too have this issue. On some places I keep falling through the terrain. It mostly happens when coming up to a steep wall etc… I am going to solve this by adding extra collision walls but somehow I wonder if there is a bug in the terrain part?
I have not been able to reproduce this on my end. Can you be a bit more specific. Are you retopologizing your terrain or is it after simply using a strong strength sculpt tool? How steep is the angle of the landscape before you see the collision error?
While I was unable to reproduce this error on my end, we have had a number of users experience this collision bug. I went ahead and put in a bug report, UE-11447 to be assessed by the development staff. Can you try the workaround suggested below and see if that fixes your error:
We just fixed a new bug in 4.7 where collision for landscape components containing XY offset data (generated by the Retopologize tool) was broken. The fix will be in 4.7.3 which should be out next week. If you’re using source code you can apply the fix directly before then if you’d like:
Thought I’d mention that I just encountered this bug in 4.10.1.
No retopology, simply sculpting and smoothing. changing the component size and then back again seemed to fix it temporarily but with more sculpting it happened again.
The fixes for this came through in 4.7. Can you list what steps you are taking to reproduce this in a clean, blank project with no additional content? Is your landscape created in editor or imported from an outside source such as World Machine?
