Hotspotting is a great technique that allows you to quickly texture a large amount of surfaces with nice edge detail while using a single material

This technique is supported by tooling like

• DreamUV, ZenUV for Blender
• UModeler for Unity

The part that currently takes the most time in hotspotting is the material setup, you need to create the final sliced atlas that can then be used on the surfaces.

I could instead provide a universal shader that allows you to simply drop in your material textures and turn any tiled material into a hotspot
