"Snap to floor" not working.Version 4.6 Preview

Hi ,

I am not sure if I should report any bugs I encounter in a preview version , but I have found that “snap to the floor” in Unreal Engine 4.6 Preview does not seem to work.

I did a restart of the engine , created a new project , made sure the default “end” shortcut key is assigned , all
with the same results.

Best Regards ,

Hi Ockertvs,

Since 4.4, we’ve been using an option in the Transform Toolbar to enable or disable actor snapping:


This seems to be working fine for me in 4.6. When you say it’s not working, are you referring to another setting? What exactly happens when you try to place an actor in the level with snapping on?

Hi Ben ,
Yes I am aware of the option described above.I really don’t know why it wasn’t working for me in 4.6 Preview at first , though after your reply I went to look again without changing any settings and it worked first time.I feel quite embarrassed , as I don’t know what caused it not to work earlier.Thank you for the kind reply , and I apologize for the inconvenience.
Best regards

It’s absolutely not an inconvenience and there’s no reason to be embarrassed. Sometimes things unexpectedly don’t work, and we want to try to minimize the problems for you guys! If this happens again for you, please feel free to reopen this post with any details you may have. Thanks!

Hi ,
I’ve been able to reproduce the problem I’ve been experiencing , after further testing.
Seems to be a problem with BSP only.

In Unreal Engine 4.5.1 , with a BSP selected within the level , shortcut key “end” would’ve snapped the BSP to the “floor” below regardless of the “surface snapping option” in the toolbar.

I created a new project in 4.5.1 , dragged a BSP Cube to my scene , positioned it above the floor , used “end” key and BSP was able to snap to the surface below.

Tried the same steps in 4.6 Preview and BSP does not snap to the surface below.When I hit “end” I do see some changes in the Outliner and Details Panel of the selected BSP.If “End” is hit with the BSP selected through the outliner , the selected actor in the outliner changes.When the BSP is selected by clicking on the BSP surface through the Level Editor ,and “End” is hit , it seems to collapse the “Surface Materials” section in the details panel of the selected BSP.

Hope this helps , and hopefully could be reproduced on your end.
Thanks again
Best regards!

Ah, I see what you’re saying now, it only seems to affect BSPs. I can verify that this is not working correctly in 4.6. I also checked our internal build and it seems to be working fine there, so this should be working again in 4.7 for BSPs. Thanks for your report!

Pleasure , and thank you.

I had same problem, BSP would snap to the floor but it wouldn’t drop to the floor. I noticed some other problems with it doing something random with certain actions, but will wait until 4.7 as the post was already closed and I haven’t tested 4.7 yet, don’t wanna be making any duplicate posts.
