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 is Per-poly collision not working properly?

Hey Guys,

I have imported a number of meshes which are relatively simple, yet the geometry is not well suited for collision decomposition, I am trying to use Per-poly collision, and from what I was told, you can use "Use complex collision as simple" to do this, however, when I enable this my collision still fails to work. Any ideas?

Cheers, Brett

I managed to solve this on my own. Turns out that when I generated the mesh, I was not creating a UBodySetup for it. This caused the editor to behave strangely and not store collision settings for the mesh (although everything looked fine). I fixed this issue and Use Complex as Simple started to work! :)

did you try Auto-Convex collision ? it might do the job depending on the shape of your meshes

I did try that, but unfortunately as I mentioned above the geometry of the mesh makes it impossible to automatically generate accurate collision meshes, which is why I was hoping to use per-poly, at least until I can manually go through and build up the collision meshes (I have a lot of meshes).

Take a look at this video and check if you do the 3rd way as it is shown in the video: https://www.youtube.com/watch?v=TTsAYpqHU-c Because normally this way works in every case (excep of backfaces -> e.g a plane. So you will be abel to walk through it from one side ^^)

I managed to solve it. It was an issue with the C++ side of my code.
