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"

Try to start from simple geometry. Make sure it's not the mesh is the issue.

Hi S-ed,

thank you for your suggestion.

It does work with simple meshes like a cube or cone but I need more complex meshes like a Tank, Ship or Airplane for the project i am working on. I have googled this issue and it seems that i am not the only one reporting Freeze when activating Fracture Mesh.

Hi AndiSel,

Fracturing complex meshes can take some time and it can exponentially increase if the Cell Site Count is higher. You say the editor freezes, so I'm assuming that it doesn't completely crash. Even on high end systems, some really complex meshes can take quite a while (30 seconds to several minutes) to run the fracture process.

If it is indefinitely hanging or crashing, feel free to upload a test asset here and I will see if I get the same results on my end.
