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"

Maybe I could just refresh the forward and backward panel.Calculate the new vector when window is on wall. then,call the ProceduralMeshComponent to refresh the mesh... I think this way may be work.If it does work,i will let you know

Hey Guys... I have solved the problem by calculating the mesh vertices and triangles on my own...

I wrote a algorithm that spilt the mesh into several triangles and then use the ProceduralMeshComponent component. It works~ It look just like this ,you can see there are two square on the mesh

Hi, Ding

I'm sorry your blog is 404ed. I would really interested to take a look at your implementation. I'm just started on UE4, wanting to create a portal on walls/floors that a player can pass through (like opening a hole on a wall/floor). I would be great if you can share your code again!
