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"

Very long road with splines?


I have a very "big" terrain, it's length is ca.20km. I want a simple road go straight in this terrain, but after 2 weeks i have no idea how to do it.

First of all, the road isn't straight, and the terrain isn't 100% flat. So my best shot would be the landscape spline tool. But that tool strecthes my mesh and materials, i can't calculate the mesh scale on each segments.. i can't tell the splines length because it isn't straight.

Then i made a spline blueprint, it has an auto-length function, so it won't cause any streching. But i can't adjust the landscape to that perfectly, and this method is very slow, and painful and my computer suffers. With this slow flow i can't really work.

How can I achieve the best road spline in Unreal? Without any paid plugins or things like that.
