When open first time a BP of some object you create and save any function in this BP, then close and open - its allright.
But, if you dont do anything in BP and close then open - you have problem.

Hey ,

Thank you for contacting us regarding blank blueprint editor issue that you’re experiencing. I have a few questions I’d like you to answer in order to assist you further:

Have you tried restarting your computer completely and opening your project up? If so, did this work for you?
Have you tried going into your project folder and deleting following folders: Intermediate, Config and Saved
Could you please create a new blueprint template and tell me whether or not this still occurs, or if it’s just this specific project?
Did you obtain editor from Source or Binary?
What version of editor are you on, you can find this by going to ‘Help’ > ‘About Unreal Editor’

Looking forward to hearing back from you, thanks!

sorry for time. was bussy

Please go into your project folder and delete following folders: Intermediate, Config and Saved. Once you’ve done that, please reopen your project and let me know whether or not that fixes issue you’re running into or not.

Can you also click on ‘Class Defaults’ and see if anything changes in Blueprint Editor for you.

Does this happen on C++ projects that you create blueprints in?

Thank you!

DenKuzn · July 26, 2015, 9:26am

I did, but nothing change.
I cant start new project with C++, becouse tne engine needs visual studio, but i have’t.

Hey,

Please follow this documentation regarding [Visual Studio and UE4][1]. Following steps within this document should allow engine to open. If you have any further questions, please let us know.

Have a wonderful day!

Hey I just found a solution. When you open it up and it just gives you blank BP click on window and pull up class defaults. It will open up panel full screen. At top there should be an option to “open full editor” highlighted in . Click that and you should be good to go.

Wow this is answer. Got this problem today with Version: 4.26.0-14830424+++UE4+Release-4.26
