[Question] Custom editor with game using some UE4 core tools

I read you cannot include the official/original tools/editor of UE4 in the game release.
But you can create custom editor in Qt with some core/tools from original UE4 Editor/Tools (all binaries) and add that editor to the game release ?

UE4 got it’s own UI system called Slate and this is what UE4 editor is using

Yes, its another option

The official prohibition in the EULA is that your game (including any editor it ships with) cannot:

Distribute or statically or dynamically link against modules in either the Developer or Editor source folders

I got a question about this and the license update.

  • Before:
    However, the Product may not consist
    of or contain any Engine Tools (i.e., the Product may not Distribute or statically or
    dynamically link against modules in either the Developer or Editor source folders)
    nor provide functionality allowing the creation of standalone products utilizing the
    Licensed Technology.

  • After:

The Product may not contain any Engine Tools.

Then the question is… this the same with other words or now you can use the modules in compiled form to use allowing the creation of editors/launchers for example ?

Basically the previous language was built into the Engine Tools definition. That definition now reads:

"Engine Tools"means (a) editors and other tools included in the Engine Code; (b) any code and modules in either the Developer or Editor folders, including in object code format, whether statically or dynamically linked; and (c) other software that may be used to develop standalone products based on the Licensed Technology.

Thank you very much, for the clarification.
