Marius Silaghi's Plug-ins for 3ds Max 2013-2022 Win

Includes:

Clothify Pro for 3ds Max 1.02
Non-destructive Cloth

Clothify Pro is a modifier for 3ds Max that makes modeling and animating cloth easy, controllable, artist-friendly, fast and non-destructive. You get instant results, no waiting around for a simulation to finish. Painful sculpting of cloth can also be avoided.

Edit a parameter and see instantly what it does. Every parameter can be controlled by soft selection, vertex weights or vertex colors, giving you unprecedented control.

Any deformation applied underneath the modifier affects the cloth so you can make use of any of the many modifiers 3ds max has like Edit Poly, Skin, FFD, Bend, Affect Region, Path Deform etc. It can also be used with the Freeform brushes. Actually it can be used with anything that deforms the mesh.

Currently it doesn't handle collisions with other objects and self-intersections, although they rarely happen if the underlying mesh isn't self-intersecting. Volume preservation is also not yet available.

Deformation Cleaner 1.0
Clean up bad deformations

Deformation Cleaner is a modifier for 3ds Max that smooths arbitrary deformations of a model without smoothing the original detail. It can be used as a fast post correction step on top of any deformation.
Here are some of the benefits you get:

Improve rig deformations.
Achieve better deformations easier and faster.
Simplify your rigging and skinning workflow.
Easily remove mesh stretching.

Jiggle 1.01
Realistic animations with Jiggle

Jiggle is a modifier plugin for 3ds Max that adds quickly and easily realistic jiggle motions to parts of animated characters and objects. It can simulate fat and muscle movements and skin sliding effects.
Here are some of the benefits you get:

You get to to ramp up your animations to another dimension of realism quickly and without effort.
You don't have to struggle anymore with complicated muscle systems and skinning methods.
You get to quickly and easily add jiggle effects to your animations.
It is multithreaded so it allows you to work with high resolution meshes.

Path Deform Pro 1.01
Intersection-Free Path Deform

Path Deform Pro is a modifier for 3ds Max that deforms models along a path without causing self-intersections unlike the standard Path Deform modifier which produces a lot of self-intersections. It produces less pinching/stretching where the path bends.
Additionally it has options for volume preservation, slink effect, rolling, rigid deformation, rotation/scaling with a curve and full control of the up vector using another spline to look at and many more. Global intersections may still occur if the mesh is very thick and the path is close to intersecting itself.
Here are some of the benefits you get:

Less self-intersections
A lot of options to get exactly the deformation you want
Save time and energy by not having the clean up bad results

Shell Pro 1.0
Intersection-Free Shell

Shell Pro is a modifier for 3ds Max that creates a shell around models without causing self-intersections unlike the standard Shell modifier which produces a lot of self-intersections. Surface details are also preserved very well.
Additionally it has options for chamfering, filleting and beveling the edge of the shell. Global intersections may still occur for high shell thickness values or the inner and outer shell may intersect for complex geometry like ears etc.
Here are some of the benefits you get:

Less self-intersections
Quickly bevel the edges of the shell
Save time and material when 3d printing hollowed models with Shell Pro
Save time and energy modeling shell like objects

Tension_Morpher 1.0
Skinning simplified with Tension Morpher

Tension Morpher is a modifier plugin for 3ds Max that quickly and easily adds realistic stretch and squash effects to parts of animated characters and objects. It also can be used to create wrinkles and preserve the volume on deforming meshes.
Here are some of the benefits you get:

You can quickly morph between different morph targets based on edge length tension and compression or based on edge angles.
You get to use my specialized TopoRelax algorithm that tries to to relax the mesh and preserve it's volume on parts of the mesh that are deformed.
You get realistic mesh deformations.
Quickly and easily add wrinkles on deforming meshes

TurboSmooth Pro 1.02
No more annoying support loops

TurboSmooth Pro is a modifier plugin for 3ds Max which produces nice smooth semi-sharp creases on your models, unlike the ugly creases that the standard TurboSmooth produces. It also give you the ability to have linear UVs which in some cases can help in the texturing pipeline.
Here are some articles by Neil Blevis that explain some of the shortcomings of the standard TurboSmooth modifier which are fixed by TurboSmooth Pro. Article 1 Article 2
Here are some of the benefits you get:

Quickly and easily set nice smooth creases either by edge weight or smoothing groups.
Don't have to struggle placing support loops.
Have more control over your mesh.
Avoid artifacts produces by support loops.

TurboTriSmooth 1.03
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.
NEW in 1.02 - Added support for semi-sharp creases based on edge crease values and smoothing groups
Here are some of the benefits you get:

Smoother results than the standard TurboSmooth for triangle meshes
Less artifacts
Nicer topology
Produces less polygons per iteration than the standard TurboSmooth
