Looks like a nice little engine.
Just didn't get how to "finish" a game to a bat or exe or such, jet.

Sorry for bumping up this thread again!

I think this engine is worth a second and third look.

It is easy to use - with the examples written in Lua you can get fast results in very few time.

It is still quite basic, but it is very well organized and lucid.

And, most important:
"The Engine has been tested on Windows, Mac and iPhone, and can be virtually used on every platform."

I know, I should learn to use the mighty Unity, but I have almost no time, while working with 3DGS. So this little engine is sort of a toy, because it starts immediately, I don't have to wait for loading any asset sets, and can start right on.

Interesting i really appreciate :
-Blender support
-Multiplatform

I have some questions :
-It is fast ? can it handle complex scene ? Does it have LOD or do you have to code some routines ?
-Does it have a GUI System ?
- Does it have level Loading/saving

Well i don't have time, but perhaps i'll give it a try
specially if it can use directly Blender models.

It doesn't use original blender files, but has an own blender exporter.
You shall build different parts of your level with different objects in blender, when exporting several objects as one mesh, the engine handles them at submeshes and only renders the required submeshes while hiding the others. I didn't test that, yet.
It has not much features, the given functions are still quite a few.

Still publishing pipelines to others than windows are missing (at least none with a free license).
There is a load level function, but no save instructions.
GUI:

If you have time to play that toy, you should spend you time to learn Unity.

What I say is - I can have a look into Maratis when I take a short break from my tasks - just _starting_ Unity - takes almost the time of that little break.
[When taking a deeper look, even starting with Unity isn't the best choice, because I still have projects pending with 3DGS - and - I have a big project plan that I should prototype first in 3DGS to illustrate, because nobody gets the idea just by my description. - But - on the other hand: Couldn't an engine like Unity offer some fast casual game making for the mobile phone market? - You see my lack of straight management! ]
