All dimensions have doubled after upgrading project from 4.3 to 4.4

I’ve attached screenshots of rough before and after measurements from the top view of a wall. Please let me know if I can fix this, or a work around to appropriately scale down all dimensions. Thank you!

Hey mister9-

This is a known issue that appears to have been fixed internally and should appear in a future release of the engine. Are you in 4.4.0 or one of the later hotfixes (4.4.1/.2/.3)?

Cheers

Luckily I backed up my project before switching engines, but even when going to 4.4.3 it still happens.

Is the scale off if you create a new project and try converting it as well?

No, and I just converted a different project and the problem doesn’t happen so I’m confused what’s going on. Is there a way for me to import a level/map (and all of its assets) from my old project into a newly created project?

You should be able to copy your content folder from your old project to the new one and have all of your levels and assets in the new project.

That actually somehow didn’t work. I copied the Content folder from my good 4.3.1 project and pasted into a newly made 4.4.3 project and my dimensions are still doubled. I’m still new to Unreal so bare with me… but where are the instance parameters like size/location stored? I actually can’t find any mention of any of my assets in the c++ code anywhere in Visual Studio. I assume that when I make a Box Brush in the editor, it automagically generates the C++ code, or am I wrong?

Just to make sure I understand what you’re saying, what are you saying didn’t work? Were you not able to copy the folder or did the copying process work but the original problem still exists?
EDIT: You may also want to try copying the specific .umap that you’re working with and move it to the Maps folder of the new project.

I tried copying the entire Content folder into a newly created 4.4.3 project and the dimensions are still roughly doubled. I tried copying just the .umap file and the same thing happens, which makes me think something is declared wrong in the map file. Is the umap file a database? Is there an easy way to manually edit or view the contents of a umap file? Thanks for the help!

It’s not possible to directly edit a .umap file. This issue has been fixed in an internal build of the engine and should be available in a future update. Let us know if you continue seeing this issue in the future.
