Great! Glad that helps.
Well so far so good. Urho3d is very fast. You can use C++, Lua, and I think there is a C# variant. I'm specifically using it because I like Lua and was looking for something lightweight. I also don't use editors, and it's very simple for me to just code and run without compiling (because luajit). It does have an editor, though, but I haven't used it.
I think most people have trouble installing it from source and so it isn't very popular. After reading the documentation and scripting api over I have a pretty solid grasp on it. Everyone keeps saying it has clean and concise code and I'm inclined to agree. The built in gui/menu system is awesome. If you're looking for lots of examples and prefabs and stuff, stick with godot. Though the U3d community on discourse is pretty good about responding for support.
If you download the binaries, there's a folder with precompiled examples. They're a little silly but you'll be able to see how well they run on your machine. Godot was slower for sure when I used it. But I'm using integrated graphics on a laptop, yet still getting great 3d frame rates with u3d.
Might be worth checking out! Let me know what you end up making, I'd love to see it.
