Hi,
There appears to be a bug with the nav mesh collision system inside a static mesh.
I have done this is a blank project in launcher version of UE 4.15
Reproduction steps:
- Open static mesh in editor
- Check “Is Dynamic Obstacle”
- Add a box collision under navigation
- Enter, Extent: 200, 200, 200, Offset: 50,50,50 then press enter
- Save asset
- No green box will appear
- Restart editor, and the nav box collision just created will not appear and the vector will be default 0,0,0 on both extent and offset
Let me know if you require any more information.
Cheers
