All Windows in Blueprint editor are gone

Development Programming & Scripting Blueprint

I create a blueprint from a class I coded in C++. After I double-click the blueprint for the first time in the Editor, it works OK (all windows show up like Default Class, Detail etc). If I close the blueprint tab and reopen it, all the useful windows are gone and I can’t do nothing.

PS: I’m new at this.

Hey ,

If you go to Window, you can get back your ‘components’, ‘my blueprint’, ‘viewport’ and your ‘details’ tabs. If you want to get the Event Graph back, please just double click on ‘Event Graph’ from within the ‘My Blueprint’ tab. The same rules apply for any construction scripts. Simply double click on the Construction Script within the ‘My Blueprint’ tab.

Let us know if we can be of any additional assistance, have a wonderful day! :slight_smile:

Hi . The Window button wouldn’t show any option for Components or viewport etc. I was not able to find those options anywhere in the interface.

How I solved the problem: after I recompiled the blueprint using the top left button, the option “Class Defaults” appeared in the Window button. From the Class Defaults tab I was able to proceed to the Full Blueprint Editor, where all options were available again.

That was a really weird bug and it didn’t happen since. Hopefully it was patched in 4.8.

Thanks.

Seems to be back for my new-install of 4.12.5. I am following the Vive setup on https://docs.unrealengine.com/latest/INT/Platforms/SteamVR/QuickStart/2/, and it tells me to add component to my VR_Pawn. There is no Component tab when I double-click on my VR_Pawn. There is also no Component option under Window dropdown menu.

Thanks for comment about going into full blueprint editor. Now it works fine.

I had this issue with a new blueprint. As a workaround, drag an instance into the game. Make some changes, then click Edit Blueprint and select Apply Instance Changes to Blueprint. Now you should be able to double click on the blueprint and it will have a pile more windows instead of just details.

I am new to UE and I have the same problem with 4.24.1. When I close a blueprint and later open it again, the interface is empty. Only the top menu is left and when i click on “windows”, there is no viewport option etc.

Thank you for the workaround.
