TurboTriSmooth 1.03 for 3ds max

https://mariussilaghi.com/products/turbotrismooth
TurboTriSmooth is a modifier for 3ds Max that subdivides triangle meshes while producing smoother results and nicer topology than the standard TurboSmooth.
It can be used on triangulated models, cloth, scans, decimated meshes, fluid simulations, terrain or on any triangle mesh.
It will automatically triangulate the models before subdivision.
