Hello.

I found a new bug in UE 4.12, built from 4.12 git branch.

When I am trying to open map in UE Editor by double click on it, Editor crashed with message box

The UE4-MyGame Editor has crashed and will close

Assertion failed: TexCoordIndex < NumTexCoords [File:e:\UnrealEngine\Engine\Source\Runtime\Engine\Public\StaticMeshResources.h] [Line: 156]

ОК

Hey -

Does this crash happen when opening any map or a specific map? If this happens on a specific map, can you send the .umap and/or the project with the .umap asset?

Hello.

Sorry, I can’t provide full project.

I’ve used 4.11 p 4 and, after 4.11, I used UE 4.12, built by my self, from commit

SHA-1: 930637bd2055d2b2916dee7e1b949eca487a0d1d

  • merge changes from dev-platform to release-4.12

It appear that pulling the level itself into a new project is not allowing me to access the level. Would it be possible to provide the full project with the level that is not opening?

Looking at the log files, the TexCoordIndex was outside the range of the NumTexCoords array. Can you let me know which preview version are you working in?

Hey ,

I’ve investigated this issue, and found that it is fixed in 4.12. This commit should resolve your issue: https://github.com/EpicGames/UnrealEngine/commit/daec52e515d830619403b2bde6bcdf576c11c151

Have a great day

Yeah, really solved!

Thanks for UE dev team!
