Well from what i see,in those games the player is probably in the middle of a mesh(big sphere,cylinder or probably something else)and i suspect the mesh has to have inverted sides(faces) for you to see inside.I did this

Its a cubemap(one from udk) and i pasted the shader on 2 udk speheres.The one on the right looks good so i decided to export it in maya>flip the faces and import it back in udk(now is the one on the left) with the same shader but everytime i do this the shader is upside down(for every mesh i tryed)and even there is some strange bending from time to time?So there is defenetly something strange with the uvs in the meshes in udk.
Still im not sure if this is the right way to approach this technique.
Here is a exaple from dracula ressurectionhttps://youtube.com/watch?v=Z6UxfjtrS6E
Im sure i can do the movement and just leave the turning of the player>than make simo small object when clicked>i teleport to them and change the sphere environment.The problem is im not sure how to map a 360 environment the correct way to a object to mimic the look.
