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"

How can I draw emmisive lines?

I'm trying to draw lines at runtime so that they show up clearly to the player. Specifically, I want to draw the simple collision boundary of any static mesh.

I found that "FKAggregateGeom::GetAggGeom" can draw these lines, but they are hard to see. How can I make them emmisive like the wireframe material?

The engine's wireframe material can be set to high emmisive, but I can't seem to use it for simple collision. It only works for complex collision.

I have included a screenshot of my current progress. Drawing the collision border definately helps, but you can see that the table's collision is much easier to see because it is emmisive.
