thanks for the feedback! i did make an outline shader but this was my first time doing 3d and i encoutered so many bugs and outdated code so had to move on. and i also want the movable objects to be more defined like you see in cartoons. where all the objects that are interactable pop out a bit more. the style is more of a constraint (i do not know how to model) everything is a square or a sprite :P
but im definetly continuing this project! first thing is trying out new ways to move objects. either something like gangbeasts or just move them with the mouse. and i definetly need to replay the witness for inspiration!
