Hey,
When placing BSP primitives on my map I noticed a lag of a second or two before it pops into the world.
Is this a known issue or is it local? My machine is clean and exceeds min specs.
Not a huge problem but It’s supposed to be instant. Is there any way to speed this up?
I had that seen that as well. Usually when I reached a count of 500+ brushes druring prototyping.
I think it has to do with the nature of BSPs (and their flexibility).
What I did first, I turned off automatic geometry rebuild. The brushes were then not showing at all (until rebuild), but that eliminated any lag.
But I quickly dropped BSPs alltogether and only use static meshes for prototyping and now I can have literally thousands of actors, without any perceivable lag.
Good idea! I’ve noticed converting them to static meshes also cleans this up.
Make the primitives, convert to SM, then use those untill you decide to use more complex models…
Nah, Im not converting brushes to meshes 
I made me a set of “SmartBrushes” that are blueprints which create brush shapes based on simple primitive meshes.
I use a simple cube to build almost anything, from walls, doorways and stairs to pillar columns and Fassade sections.
The only thing that is not possible at the moment (and prevents UE4 from having a “Prefab” system) is the fact that you cannot modify blueprint child components within a blueprint…
