License attribution clarification

[AndreaMonzini]

Hello,
as a free and open source supporter i prefer to use software like Blender, UPBGE, Range Engine, Armory3D, Godot Engine among the others.
So to avoid misunderstandings, explore and hopefully to use UPBGE with a good attitude, i gently ask a clarification about the code developed for the "UPBGE-logicnodes" that is under the GPL license:

As i read from this forum discussion "Armory" (3D) and "Lubos" are mentioned several times:
https://blenderartists.org/t/blender-game-logic-nodes-upbge-compatible/1131906?page=3

• is the "UPBGE-logicnodes" code a derivative code of Armory3D logicnode that is under the zlib/libpng License ?

https://github.com/armory3d/armory/tree/main/Sources/armory/logicnode
https://github.com/armory3d/armory/blob/main/LICENSE.md

If the answer is yes, the correct attribution is necessary to follow the license rules.

Beside legal license obligations, it would be nice to dedicate the right words to recognise the work and inspiration we have each other.

I praise collaborations between free and open source projects so thank you to all the developers and contributors for the opportunity to use, study, share free and open source software like Blender, UPBGE, Range Engine, Armory3D, Godot Engine,

Andrea
