Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Why are models falling through in some parts of my landscape?

I am using 4.7.2 version of UE4. Early I converted this project from 4.7.1 to 4.7.2 UE4 version. 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 just fixed a 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:

Hey there,

I'm having the same exact problem. However this only occurs on landscape i haven't touched in a little while. My map is quite huge so it's normal some parts are done that i don't touch because it's done. But recently i tried something out in an area that was done but randomly started falling through the landscape with my FirstpersonCharacter and my Vehicle. Also on a side note my meshes, as soon as i turn on Physics it just falls through the ground on every spot on the map. However everything is set at BlockAll. Also i haven't used Repotologize as said in the other posts. Is there any idea why my meshes would fall through as soon i turn on Physics? I've asked 3 people with months of expierence on UE4 But they didn't see any problem either. Is this because of the same bug?

Kind regards

Hi CrazySiberianScientist,

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:
