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"

Old Landscape Terrain physics issue

There have been more reports on the forum regarding this issue. I can see that so far, up to version 4.4, it still hasn't been fixed. Issue is: After working with the landscape tools for putting together a terrain, the physics stops working at some point for everything except pawn blueprints. CCD doesn't help one bit, nor typing the "RecreateLandscapeCollision" command. I don't know when this happens exactly, I just end up frustrated, with a lot of wasted time having to recreate the terrain I need - which usually ends up with it breaking again.. and again. Unworkable.

This issue popped up since earlier versions of UE4 and the "fix" has always been reported by having to remake the terrain. But this should not be marked a solution in any way! It doesn't always work and keeps sending you back, reworking the same terrain over and over..

Hi Virgil Tuser,

I have not been able to reproduce this thus far, are there any specific steps that I should take to be able to do so? Currently I have an 8x8 landscape with 1x1 sections and simply modified the landscape, ensuring I altered every section to a significant degree before testing. Any additional information to be able to reproduce this on my end would be greatly appreciated. Thank you!

I wish I knew the steps required in order to break the terrain, this way I could at least avoid them by a certain degree. But I have no idea when this happens precisely.. My terrain is also 8x8 with just 1 section.

How is your collision set up in the details panel of your landscape and physics objects?
