Good day,

I just want to ask if I have to disclose my source code?

having condition of:

  1. I use my own MODIFIED blender as world editor, level editor, game content creation.

  2. I am not selling my own modified blender, I am the only one who will use it.

  3. I have other game engine that will load the things I made in the blender.

Also, if the answer is YES, can I just make a plugin using python so that I can accomplish the list above and not be required to disclose my source code of my created game and my modified blender?

If you don't re-distribute the modified Blender, you can do what you like.

You can sell your own modified Blender if you like, as long as you include the source code.
