Where is a 3D game engine can be used without problem without programming skills?

Seems like a duplicate of this post, "I am looking for a 3D game engine to create 3D games without programming you know someone?"...

Anyway, with that out of the way:

Any game engine with a visual scripting language will be easier to program in, but ultimately you'll still need to know some programming logic to make a game, as programming of some form is what tells the game how to run. I think the only way you could get around not needing to know any programming at all is by making skins/resource-changes that only alter the visuals of a premade/predefined game.

There are many game engines with visual script languages. Godot has its own visual scripting language, Unreal engine has its own as well, and Unity I believe acquired a visual scripting plugin and made it free (Bolt, I think...), Construct 2/3 also has a visual programming language I've heard good things about, and finally Stencyl has a visual scripting system similar to the one seen in Scratch.

That said, you don't need to be a master of programming, visual or text-based, to make games! Once you know the basics, its pretty easy to make games from there. I would highly recommend taking some beginner game development tutorials that look interesting to you. I'd also suggest looking at some beginner programming tutorials or books, especially if the programming parts of a tutorial do not make sense, as they can help explain the foundations of programming itself.

I don't have programming skills. And developping my simple 2D game is a nightmare. If you don't learn computer science don't try to make games, you will get frustrations everyday.

Even visual programming is well, programming. Don't expect to ever find a game engine free of programming. No such thing exists. But if you find a template project or a game to use as a basis for a 'total conversion' you might be able to cut down on significant amount of the work. Make sure to pay close attention to the games licensing model though.

Unfortunately, you probably can't find an engine with no programming at all. As @Megalomaniak says, even visual programming is still in a way programming. It makes some things easier, but you still have to understand the logic of coding to make any progress.

There are some more specialized engines, like Ren'Py (for visual novels) or RPG Maker (for 16-bit RPGs) that have easier barriers to entry, but you still need some understanding to work with them. Also, various engines have visual scripting (including Godot) so you can try that if you want.

Visual scripting is a best option for the one who don't want to code,but programming via visual scripting is slow.
