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 to optimize modular building meshes?

Hello everyone,

I made my own modular building kits to create a city faster. As it's known, all buildings are created by a construction function of a blueprint. Basically, one building has ~300 static mesh components. It affects the FPS. To optimize my map, what should I do? Should I merge actors? If so, should I merge buildings one by one or by grouping them?

One way is to have the BP build it and then use the mesh proxy system to group and optimize them. At least that's how I'm doing it - looking forward to hearing other ways.

I just now tried the proxy system but the quality and the materials weren't same. The meshes I'm using are a bit complex. For example, I'm using a cubemap for window materials to create interior demonstration. However, this system is very useful for the object which the player cannot get close to.

There are some options to handle this issue, but I don't know which one is best approach.
