besides the few bugs I came across, this is a very lovely little virtual tour of the miao miao/appy home =) I'm kind of shocked you managed to completely transfer your visual style into the context of RPG maker though, that does not at all sound easy ''o_o
ok editing this cause I just read the readme and extra notes, it genuinely DOES sound like a nightmare to achieve this look in RPG maker, working with plugins in any program is already iffy as it is (for example pribambase doesnt show UVs for any version of blender post 3.6 orz,) that combined with having to figure out how to properly layer and align the background, the fact you kept pushing through for as long as you could is impressive.
