Hi. I have large landscape with many foliage. Objects count in my level: 44450, memory used by Editor: 2Gb.
My PC: inte i5 4570, Nvidia GTX 660, 8 Gb Ram, Windows 8.1 64 bit.
I move or change size of any BSP, or add new BSP, or PIE/simulate, or “Build geometry”. Then Editor don’t respond for about 10 seconds. It infuriates. How to get rid of this?
Thanks.
Text after my action from my “Output Log”:

Depending on your engine version there may be an option to tell BSP not to auto build which causes many problems. I think they removed/moved it in 4.3 so not sure on which engine version this existed in. If you turn it off you will have to do your own “Build Geometry” from the viewport Build menu to update your brushes.
It’s talked about in the answer to this post:
“Try turning off update bsp automatically. This is located in Edit>EditorPreferences>Miscellaneous. There is a known bug with this specific feature that is causing slow and freeze issues.”
Well that is the problem for certain. When you have a large landscape with a lot of foliage being rendered all at once it will cause lag no matter what your system specs are. What you will want to do is use cull distance to only render the foliage you can see at that moment, which will reduce your draw calls immensely. I would also recommend level streaming for different areas of your map to prevent rendering a lot of unnecessary portions of the map at once. You can use the “move to level” landscape feature to move individual tiles of landscape to sublevels in the levels window to help you determine how you want streaming to occur.
Foliage in my level rendered NOT all at once, i use “Culling” and “Clustering”.
I understand, geometry is in conjunction with vegetation, and after build geometry engine corrects all vegetation. But the engine corrects all vegetation on a level that is not reasonable.
It would be wise not to update the all vegetation when compiling geometry and allow the user to correct himself vegetation after compiling geometry.
If i don’t right, sorry.
I can’t use level streaming because NavMesh don’t work with it.
“Move to level” landscape uncomfortable to use, thanks.
Unfortunately without some form of level streaming or other method to reduce the amount of data being rendered, the engine will run slowly as you have mentioned. You can potentially use static meshes instead of bsp’s to alleviate some of this (and eventually bsp’s should be converted to static meshes to reduce their resource cost anyways), but otherwise this delay more than likely will continue to increase as you put more information into the editor. Another option would be to lower the LOD on your meshes the further you move away from them until they are culled out completely to try and reduce the information present all at once. Turning off “update bsps automatically” in the Editor preferences window and realtime in the viewport may help alleviate some of the slow responsiveness. Finally, you can use sublevels to hold data such as lighting, static meshes, etc. so that you can turn those sublevels off when not working on them, reducing the amount of data being rendered while you are in the editor.
