That would probably be a challenge.
A few ideas:
A mini 3d sculptor for the mug. Draw a clear hollow 3d cube, with 30' slant
at the inner face of each sub cube, and add a sippy straw at the upper
corner to the bottom. Similar to the mega Rubik's Cube. Offers unique
customization, Inhouse control, monetization, visibility, and something
for every other company to copy. Plus once you get Gud' you can expand to
7DTD zombie sippy cup requests. You could even autograph it at the push
of a button. "When life gives you lemons, Build a lemonade stand"
MM if you follow the thought posted before about the unified Megabiome
would it be possible to add a biomes inclusion, that does not deal with
texture maps of visuals. Instead deals with altitude, and spat3 map
coloring.
Example: City streets, city yards, 5 present biomes, paths, highway, rad
level 1 2 3, water size level 1 2 3, mountain slopes, mountain paths.
plus say 10 custom string names to be added by modders. That would be an
allocation of 27 biomes/zones that can have specified or customized spawn
groups that change depending upon your location on the map. all that would
be necessary is to paint the designated colors to a splat3 map.
