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"

Huge amount of Meshes (Actors) performance?

Hi, I want to make a landscape level with a forest. However the level is kind of big and to make it look realistic i have to spawn 6000 or more trees. I used the speedtree conifer, which comes with LOD and the framerate drops to under 10. My problem is that this is only with trees and i would like to have a lot more meshes like rocks etc. Is there a solution to keep the performance up even with that much actors?

-plan your map carefully -> hills -when the trees are behind a hill you could cull them -I dont have experience with speedtree, but a very low poly 3rd LOD channel would increase the performance -create your own low poly trees -> e.g the ones for our game have around 2000 tris in LOD0 (it even goes down to 1000 tris) -cull small plants like grass, bushes,....

Billboards are also commonly used for far away trees, especially if they are "outside" the playable part of the level.
