4.13 absolutely DESTROYED sections of my level

I have created an apartment building in unreal… and some of the rooms are duplicates… so usually i would just attach them or group them… dont remember which… and i would duplicate and rotate it into position. Sometimes even scale it in -1 to be a mirrored version.

Just converted my project to 4.13… and some parts of my level are just all over the place… props all over props not visible… positions shifted in that room… its just weird stuff… totally destroyed… see the screen shots with correct vs 4.13 destroyed.

Hi ,

  • Does this occur in a clean, blank project with no additional content or is this limited to one project?
  • What steps can I take to reproduce this on my end?
  • Are these BSPs or Static Meshes?
  • Are any of the actors in sublevels? If so, are the sublevels hidden?

all static meshes. They are all in 1 sublevel… though others exist the problem does not extend to them.

They are all static meshes.

My assumption is what i wrote in the top of this… the meshes that have hte problems were created through the means of me creating 1 apartment unit modularly… Then i beleive i may have attached all peices onto 1 of the static meshes in unreal so they would move and scale together. (grouping i dont think scales correctly.) So then i duplicated scaled it in negative 1 rotated the entire apartment unit into position… then detached it all… works fine … But when i downloaded unreal 4.13 i opened a copy of the project in unreal 4.13 and when i viewed the level… that duplicated and scaled room static mesh modular peices were all over the place…

I couldnt tell u if it happens in a clean or blank project or not.

Do you have any steps I can take to reproduce this on my end?

Unfortunately I was unable to reproduce this with the steps provided. Do you have a sample project the error is occurring in I can take a look at?

Only steps i can think of is what my assumption was… from attaching objects to another object, duplicating. scaling that object -1 so the rest scale with it, detaching it… saving… and i guess then opening the project in 4.13 as a copy… start with 4.12.

unfortunately its huge…file size wise… i dont know if creating a sample would work… but i dont even know how i can send you a project like that… how do u send only used static meshes and textures?

You also try rotating and scaling both :stuck_out_tongue: and grouping and ungrouping … it only happens in teh mirrored copy room… so its definently having to do with that…

maybe try doing rotation of attached or grouped stuff instead of scale… with the attached stuff… i just realized the room thats broken isnt even scaled… its just rotated into position…

Another room has -1x and -1 y … but that room is fine…

dont remember if hte third room is a duplicate of that room back to 1 x 1 y… of if it was just rotated from the original room that was never scaled… its just odd that this is happening at all as an issue.

The plot thickens… I actually found something rather interesting. In the new 4.13 version… the level is using the whole sub level set up with multiple levels in the same directory. If i open the apartment building level alone(not as a sublevel)… the room is not messed up, but if i open the main level and go to window → levels and load up the level that way… the room is screwed up with things moved all over…

I have no idea why that makes a difference , but it does… it makes no sense.

Also i am unable to replicate it outside my level… no idea what to do to make this happen, i just know now that the sub level set up causes the problem where the map loaded alone the problem does not exist… what can i do?

I tried copy and pasting the level into another directory where it loaded fine, but then i created a new “main level” that had world composition on and loaded that level. I used then went to the Window → Levels and loaded the problem level and the issue was still there… So its not hte world composition level thats the problem… its the combo of any main world composition level used to load this apartment level. Wtf? its just lots of stuff is rotated what seems to be 180 degrees in that room.

Without using world composition…

I literally tried to copy and paste the entire level into a new level for testing purposes with odd results… some of the walls in that room that are rotated… at -90… (correct would be 90…) Cannot be rotated back to 90. If i enter 90 as a value… it literally snaps itself back to -90 automatically. wtf???

UPDATE
I loaded up that copy paste version of the apartment building as a new level again only to realize if i enter 90 degrees as z rotate for any static mesh in that room… it snaps it to -89. so i cant rotate any mesh that is a problem mesh to 90 degrees… what on earth is going on with this engine and this level.

Hi ,

I’ve tried the above suggestions and have not been able to reproduce the error on my end. Do you have any other steps or a sample project I can look at to recreate this error on my end?

Hi ,
