Seeing objects farther than the space in front of you was not a rendering quirk or limitation but rather a design choice. When I was originally making it for the jam, having to draw multiple sized sprites was not something I had time for so I didn’t implement it, and in the classic games that inspired the plugin (specifically Wizardry and the original SMT) you can’t see chests, etc, until they are in front of you anyway so it worked.
It’s not something I’ll be building into the plugin (it’s finished besides possible bug fixes with newer versions of GBS) but if you decide to use it, you’re more than welcome to build that out.
