Which game engine to choose for Linux?

Question

linux

Hayushki!
I'm sitting under Arch. UE4 is still fat for me (in terms of use-and-work).
Requirements for the engine:
1. Full support for 3D space.
2.Full-fledged editors (particles, models, etc.).
3. Rendering is fully implemented on OpenGL. Without Dicks and other things.
4. All sorts of goodies like LightRays (at least fake).
5. Modular system for expanding functionality.
6. Cross compilation.
7. The ability to package and compile the final product (for example, Unity or Anril).
8. It follows from paragraph 7 that resources are closed for the final product (very desirable).
9. Small resource consumption.
10. The main language for both scripting and writing additional modules is C ++. Or at least C.
11. Low cost (within 1K of greenery).
Sobsno this is what I would like to see in the proposed engine.
Well, if there is none (in general, nothing is found on all points), then:
1. Open code.
2.Written in C++/C.
3. GNU LGLP2/CC license (the most open).
4. Has completed editors, but not advanced ones (to the extreme and without them).
5. Small amount of code.
At the moment I'm considering Coffe/Maratis/Urho3D engines.
In general, I am ready (with my heart and soul) to add, finish and polish to a "brilliance".
And of course, so that all of them fully go to Linux (Arch).
I will listen to all options and answer all.
Do not throw links to the devmaster. I myself know what you can see there. It's just interesting to listen to people who will say what and offer.

Answer 1

Unity3D

Answer 2

There is such irrlicht , it is written that it can be started under linux (it starts where there is SDL), but I did not check it myself. There are sources, there is an OpenGL renderer, there are even a couple of editors, and of course C++.

Her expert but heard something, if the problem is in the bubble.

If use-and-work is real, then even though I don’t work in this area, I would recommend betting on the industry leader.
