I want to create a Dimensions where when

See a tutorial on Unity colliders and trigger colliders. You can make a transparent trigger collider and when the collider of your player and that door collide, you can use scripting to load the desired scene.

[jaunty ravine]

Man you just have to set up both your 2d and 3d scenes separately and move between them like i said above. There is no magical way to convert from 2d to 3d.

I dont really get your idea.

well your character would be turned to 3d as well from 2d?

Then passing character attributes is all scripting game. Can't really help with that.

okey , Let me give a example of a pparticular famous game

IN GTA game when we enter shop ( but when we enter the shop it show us in 3D and also after exit) we take different clothes , different Accessories / or Hair style.
when we exit the character come out whatever you have purchased.

The Shop Scene I want to make it as 2D and when the character comes out the change or purchased thigs should be visible on the character
