When building landscape, UE4 created “,16,16,16,16,PF_B8G8R8A8,16,16,1,1,0,TEXTUREGROUP_Terrain_Weightmap,/Game/Shipyard_v06.Texture2D_158,NO,0” Texture which it references within it self, but when you try to duplicate map, it fails to save cause of external reference to that texture ( Shipyard_v06.Texture2D_158 ).

Hi LexCurtis -

Thank you for your report. We have assigned this issue to a member of our support staff, and they will begin investigation as soon as possible. In the meantime, Can you provide us with a breakdown of the landscape size and material setup you are using so we can try to closely replicate the issue you are describing, and feel free to edit your post if you have additional information to provide:

Thank you -

Eric Ketchum

Hey LexCurtis,

If you would post a screen shot of what you are experiencing and the steps you took to create this issue I will look into this issue.

Thanks,

Hey LexCurtis,

I haven’t heard from you in a few days. I was wondering if you were still experiencing this issue.

Thanks,

Hey LexCurtis,

Due to inactivity and tracking purposes I will be moving this from Bug reports to Rendering. If you are still having this issue than please post to this again.

I will continue to investigate this matter at that time.

Thanks,

Hi, sorry for not answering your questions. I was on vacation. We have a scene which has a landscape. Landscape generates custom textures… When you try to duplicate level you get this error of texture external reference. You can get around this by saving a level as "save as… " and give it a different name. Although this resolves this problem I thought that you could benefit from this error to find and trace eventual bug. Also, when you duplicate scene and you try to save it UE crashes. When UE crashed I sent error report.

Regards,
Lex

The landscape that we are using is top-down city from market place.

Hey Lex,

Whenever you duplicate a level, or any file, there will always be naming convention issues if they are called the exact same thing.

This is why you are unable to save files with the same name in the same folder on your computer.

What happens is the second level, named the same thing, is trying to reference external files from your computer and put call that information at the same time your first level is.

Usually you are able to right click on your map file inside of your content browser and select duplicate. This duplicate should add a 2 at the end of it. If it does not then you will need to change the name to fix the referencing issue.

There has been a bug reported for crashes occurring while trying to open duplicated map files.

Thanks,

No, that is not it. You try to duplicate it, you name it differently but it wont save cause of external reference, when you try then to save it, it crashes. When you make save as than it is ok. Please read original post,

Hey Lex,

I did read your original text. I gave a rather broad description of how this error could have occurred.

Some troubleshooting steps for you is :

" Do this inside of your project files not while in your editor "

1.) Simply rename the folder that your Landscape is In
2.) Run the project
3.) Rename folder to previous name again
4.) Run the project again

Then recreate the duplication and try to save.

It almost sounds as if the duplication is not creating a separate file inside of your project files.

This ties back into my previous post.

Thanks,
