I"m trying to vertically line up two BSP blocks, and while it works to use keyboard to line them up horizontally, vertical won’t move incrementally at all.
Is this by design if not, what keypress do I need ?
thx
Turn off grid snapping: UE4: 27 Step Crash Course to Getting Started with Unreal Engine 4 for Beginners Tutorial - YouTube
Generally speaking, you rarely need precise movement when placing stuff in your scene, and grid snapping makes them line up (if you place walls, cover points, etc), so they don’t intersect with each other.
It was already off, as this is far more complex than grid based positioning. I’m prob. at limit of bsp placement, I suspected I was honestly, - going to have to get heavy into 3d and get done there 
Or you could “collapse” some of them down to static meshes, by selecting a bunch together, and from the Details panel, under Brush Settings (click the down arrow first, to expose advanced parameters), there’s a “Create Static Mesh” button.
BSP geometry has its performance overhead, sure (and for prototyping they’re more than all right), but I’m not sure this has anything to do with positioning them…
Here’s something else you could try: copy-paste their values from the Z axis, if you want both of them to share the same height, or, if they have different height dimensions, you could drag both BSP blocks in the air, press the “End” key to snap them to a flat surface, then go into the left/right/front orthographic view and use the Up/Down arrow keys to position them on the Z axis.
Ya I"lll remember that good ideas, I got it working as its just temp as I flush out level anyway , so ya.
BSP functions are very nice actually, with a bit of creativity, exploring the option you can get some nice creations
