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"

Foliage lasso & select crashes graphics card

I'm using a GTX 650 and ever since upgrading to Unreal Engine 4.3, my foliage crashes when I use the Lasso tool and Click + Left CTRL to select foliage. This also happens when I click Select and attempt to select foliage.

I have the two SpeedTree sample trees (Broadleaf_Desktop and Conifer_Desktop), and some other foliage that I placed in.

Hi MattCan,

I am looking into this issue, but I have a couple of questions. Could you please provide your DxDiag, Crash Callstack and Log files? Where to locate those can be found here:


Does this only occur with the one map or can you make the crash occur on a new map? If you use different meshes than the SpeedTree, does is occur? Any additional information about reproduction may help.

Thank you,

DxDiag: https://www.dropbox.com/s/bl9u49ot7oj93at/DxDiag.txt Log: https://www.dropbox.com/s/xukww5kmqrc5pip/MyProject.log

Crash Callstack gives me this message:


You do not have any debugging symbols required to display the callstack for this crash.

I tried each of the different meshes that were in the foliage down by themself, and I isolated it to the crash only happening when SpeedTree models are being used in the foliage layer.
