Is there any way to stop Blender from showing the file explorer, Preferences and Render results in new floating windows and just show those editors as part of the inerface?


I assume you're looking for fullscreen by default.

Open a new blank file. Go to Window > Toggle Fullscreen Window. Then, go to File > Defaults > Save Startup File


To stop renders and file browsers from popping up in new windows, go to Edit > Preferences.

Then select Interface > Editors > Temporary Windows.

Keep User Interface will not make any changes to the user UI when you press render. If there is an Image Editor set to Render Preview open, it'll display in there.

Fullscreen will replace your current window with a fullscreen render preview/file explorer.

Image Editor will replace the current editing window to an Image Editor set to render preview (for ex. your default 3D viewport will be switched to Image Editor it that was open)



If you want to keep the current interface without any floating windows all you need to do is change the editor type or Toggle the active window, by selecting it on the top left, or selecting the shortcut of the editor you want. The file browser is Shift+F1. To go back to the 3D viewport press Shift+F5. Rendered images will be in the Image Editor or Shift+F10

To toggle the current active window into the preferences window you need create a new shortcut (version 2.8 has no pre-assigned default).

To edit the preferences and add a new shortcut: Open the preferences window>keymap open the window section. Press on Add New to a new shortcut : enter image description here

Type screen_space_type_set_or_cycle and select a combination of keys of your choice (in previous versions of blender it was Ctrl+Alt+U) and select the preferences window as "type" on the bottom left.

Then Click on the top right of the screen to show the option to save the preferences to make the change permanent.

  • $\begingroup$ The Preferences window doesn't honor the Temporary Windows settings. And the new shortcut workaround doesn't work in my Blender 2.81a installation. But I think I'll have to live with it. $\endgroup$ – Phantômaxx Jan 1 '20 at 12:06
  • $\begingroup$ Using the shortcut to Toggle the preferences editor does work. $\endgroup$ – user1853 Jan 1 '20 at 19:43

  • $\begingroup$ Just tried it in windows... it does work. Make sure you are typing screen_space_type_set_or_cycle and selecting the window type at the bottom. All you are creating is a window toggle. $\endgroup$ – user1853 Jan 5 '20 at 20:55
