Will you guys make the doors 'see-through' instead of using a texture?
Don't think it's neccesary in most cases since a simple wooden door should do. However for the barber shop they showed some images of transparent glass looking directly into the barber shop so I guess it can be done.
Wish I knew coding and/or modelling to help out, but sadly I don't know a lot more then the theory behind it. I once tried Blender but it was super confusing at the time, so now I just stick to 2D image editing just as a hobby.
