To speed up UV unwrapping in 3ds Max, simplify your model’s geometry, use automated tools like Quick Peel, and hide unused faces.
Simplifying polygon count reduces the faces the software processes, while Quick Peel generates base UVs faster than manual work. Hiding non-visible elements (e.g., internal surfaces) focuses the unwrap engine on necessary areas, cutting calculation time.
For high-poly models, use ProOptimizer to temporarily lower poly count for unwrapping, then Transfer UVWs to apply the same UVs to the original—this saves time without losing final detail.
