A blank window shows after opening an actor blueprint

Hello,
recently I’ve encountered a bug I suppose. When i try to open a blueprint of something inheriting from AActor like on this screenshot :

I got blank screen instead of editor :

There’s one exception form this: when I create new Actor blueprint I got a proper editor screen like this :

Is there any solution to this already?

Regards

Happens to me as well. In 4.7.6 and 4.8.1. Created a new blank blueprint project in 4.8.1 and tried again, same problem. Can open once after the blueprint is created but not after that. Only “solution” is to toss it out and recreate the blueprint from scratch every time you need to edit it.

If you open a blueprint and the view is mostly blank like above use the menu of that blueprint editor window and click on Window->Class Defaults

This will show you a message at the top that says “Note: This is a data only blueprint, so only the default values are shown. It does not have any script or variables. If you want to add some, Open the Full Blueprint Editor

Click the blue link that reads “Open the Full Blueprint Editor.” You will now be able to use that blueprint again like normal.

Why this is happening I do not know. But this will help you get around this bug.

Edit: Test in 4.8.3

I have this issue too. (4.8.3)

Thanks, your suggestion worked.

I’m using v4.10.4 and I just got the blank screen so this isn’t fixed yet.

I ran into this problem just now. Found that removing the DefaultEditor.ini file from the configs folder then loading up my project reset all my windows to default, refilling any blueprint that had missing windows.

Then putting the DefaultEditor.ini file back afterwords.

Thank You very much!

yep head same problem , i decided to leave it be , another day i check tutorials i flowed and she said it how to get back, right there where i ended xD
anyway v 4.16 still there

For me it fixed removing %localappdata%\UnrealEngine*

This is Happening to me right now in 5.1
