Runtime Graffiti / Spray Paint System
๐จ Runtime Graffiti / Spray Paint System
Runtime Graffiti / Spray Paint System is a Unity asset for adding interactive spray painting to first-person games, sandbox projects, urban environments, and creative gameplay systems.
The package lets players spray paint directly onto walls and UV-mapped objects during runtime. Paint is applied through mesh UV coordinates, so drawings appear on the actual surface instead of being placed as decals.
Add runtime graffiti, wall painting, erasing, color switching, texture saving, and creative surface drawing to your Unity project.
