I need help making a 3d game engine that can have full models instead of the normal super tall walls and sprites that just look in the players direction,
if anyone knows of any already made 3d engines that can act like this while also being easy to code with and model please put it in the comments.
Additional things that i can't realy explain in the context above:

1. The models need hitboxes
2. When I say easy to code with I mean easy to make changes to
3. It needs to able to make interactive models so that I can make npc dialogue and minigame triggers
4. I need to be able to animate models with retaliative ease
Please help me.

Are you sure you know enough code to even attempt a 3D game engine? They are really complicated. (At least to me)

The game engine that im trying to make is deliberately made to be more simple than most 3d game engines to make it easier to work with. (ie Making big edits to the code and adding models.).

But I can code say a ray caster.

Dang, you know a lot more code than me.
maybe this one might work

I'm sorry to say that it is near impossible to create a 3d modelling tool on Scratch. Try using an external tool like blender and then import the .obj file into a list.
