Short answer pls: Yes/No?
If yes, how.

There’s no collision inside details panel for brushes. Even when i am changing engine’s code and make Collision presets visible inside Details for Brushes, even then if i change to NoCollision or any other preset, BSP is still constantly blocking everything. (UE4.1.0)

Changing collision isn’t possible with BSP’s, they are essentially made for blocking out your level and then changing them out for a custom created static mesh later on.

If you would like to have no collision on the BSP first you must convert them into a Static Mesh.

  1. To do this, create your BSP then under the Details panel > Brush Settings > click Create Static Mesh.

  2. You will see that the geometry says Invalid Light Map. To fix this, open up the new Static Mesh you made by double clicking it in the Content Browser.

  3. In the Static Mesh Editor go up to the Window tab and click Generate Unique UVs.

  4. Under the new Generate Unique UVs tabe hit Apply.

  5. Go to the Details panel > Static Mesh Settings > Light Map Resolution and type 1.

I hope this helps.

Thanks, TJ

Ok, thx, i will assume this answer as “NO”, i cant make Brush non-blocking directly. So if i want to change collision for Brush, i have to convert it to StaticMesh first.

Not is a good solution, but is a solution.
If you want only create a mesh correctly : basic - > typeFigure - > Aply Material (in this material - > Adjust Collision - > no collision)

But the problem is with static meshes you can’t adjust the texture size, if you example have large skyscrapers you can adjust the texture, with static mesh the texture becomes very stretched because of large structure
