I am using 4.7.2 version of UE4.
Why are models falling through in some parts of my landscape?
For example:
I created some mountain-style landscape and add some foliage to it. Then I add First Person Character and play by it. In some parts of landscape(mostly in skew surface) this FPC are falling through landscape surface.
What is the problem?
We have a project that was converted from 4.6 to 4.7.2 and encountering the same issues. Its not on all the terrain but some random blocks of the terrain you just fall right through. (Its almost as if the collision is not working on them blocks of terrain for whatever reasion.
I converted this project from 4.7.1 to 4.7.2.
Why developers keep silence? I don’t wish remake all landscape:mad:
Check wireframes and see if there’s something wrong with mesh tesselation…
In wireframe view mode my landscape hasn’t any wrong vertices and polygons.
Also when I am playing FPC collides with invisible obstacles which have very big height.
Hey CrazySiberianScientist,
Try having a look at your Collision Mip Level as well as your Collision Thickness within the details panel of your selected Landscape.
**Collision Mip Level **- Landscape LOD’s to use for collision tests. Higher numbers use less memory and process faster, but are less accurate.
Collision Thickness - Thickness of collision surface, in unreal units.
I hope these suggestions work for you, but if you are still having some trouble try creating an AnswerHub post so we can help you troubleshoot the issue further. Making AnswerHub posts is beneficial to the community as well since others might come across the same issue as yourself and need some help.
Cheers,
Thanks, but this didn’t help to me. I tried to change this parameters and there is no any effect

Sorry for the Necro.
I was having the same problem in UE5 with regards to collision not functioning correctly. My third person character was floating above some of the terrain and passing through other parts of the terrain. The way I fixed it…
Click on your Landscape actor, search for LOD Distribution and my LOD 0 Screen size was a bigger number than my LOD 0. I set my screen size to a lesser number than my LOD 0 and the problem was solved.
