How can I use a spritesheet in a "3D" game

I know about paper2d but i don’t know if I can use it for a full 3d game(besides the characters),
Please help

So you’d like to make a 2.5D look?

You can use sprites in 3D so you can have your 2D Sprite characters in a 3D world. Just angle the camera slightly and keep it fixed. That should give you the desired look if I understand well your problem.

Thx but are their any tutorials similar subjects by any chance

How do I import the sprites to the game from another project?
