Freeze after release mouse button during terrain painting/editing

Hi,
I get 1-2 second freeze after release mouse during painting/editing terrain, I turn off rebuild navigation and light, someone know what can be the reason for this freeze ??

I currently have the same issue, it only seems to do this on a newly created landscape within my level, the other landscapes within the same level seem to not have this issue.

There are two things which can rebuild other than navigation and lighting:

  1. Collision
  2. Material shaders

Materials should build in the background, so shouldn’t cause a freeze. So most likely it is your landscape collision.

Thx Gareth for answer, but your answer don’t solve my problem. If problem is with rebuild collision, what can I do to no have these freeze ?

I don’t think there’s much you can do, apart from using a lower-resolution landscape so that there is less to build.

Are you using a laptop?
