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"

Procedural quadtree mesh

I'm trying to implement planet rendering. Following this topic I got the main idea. So I need to generate a mesh with higher amount of polygons near player and lower amount further:

mesh

This wiki article shows how to generate procedural mesh. However I can't get how to modify this mesh on-fly. If I set new triangle array will this work effectively? Is there any caching system I could break?

Also I wonder how to apply different materials for different tiles? GeneratedMeshComponent allows just one material for the entire mesh. I have my terrain texture split onto squads: one for far plane, four for next level of detail, sixteen than and so on. I plan to have a base material and than instance it for every tile. How to apply them for GeneratedMeshComponent? Should I care about memory or the engine will perform optimization for me?
