Hi friends 
I’m new in Ue4
I want to make forest scene bjt when I add foliage (trees,grass,rocks) my FPS drops
Can you give me some advice how to solve thi problem ? I’m using kite demo asset
You should create LODs for all of the assets you are using, that way the further away meshes render less polys in your scene…that will help out a lot. The next step would be to optimize the materials you are using to lower your draw calls and texture usage…keep in mind that the Kite Demo assets were meant for a very high end machine to run them and using them in a normal project fresh from the demo isn’t a very good idea without doing some additional optimizations on them.
