Modifiers & Their Functions in 3DS Max 

1️⃣ Symmetry Modifier 🔄

• Creates a mirrored copy of the geometry along an axis.
• Use the Mirror in the modifier stack drop-down to adjust the symmetry plane.
• Can be used on X, Y, and Z axes simultaneously.

✅ Tip: Use the Flip button to swap mirrored sides.

2️⃣ Mirror Modifier 🔁

• Flips an object without needing a mirrored duplicate.
• Allows control over X, Y, and Z axes mirroring.

3️⃣ FFD (Free-Form Deformation) Box 📦

• Creates a bounding control cage to manipulate an object.
• Use Control Points to push, pull, and distort the shape.
• Works well for organic modeling & soft adjustments.

✅ Tip: Increase segment count before applying FFD for finer control.

4️⃣ Bend Modifier 🌊

• Curves an object based on an angle and direction.
• Can limit effect using Upper & Lower Limits.
• Adjust bending axis (X, Y, or Z).

✅ Tip: Add more segments to your object to prevent jagged deformations.

5️⃣ Taper Modifier 🔺

• Scales one side of an object while keeping the other fixed.
• Adjust amount & axis to control tapering effect.
• Can be used to make cone-like shapes or distorted cylinders.

6️⃣ TurboSmooth Modifier 🌀

• Subdivides polygons to create smoother surfaces.
• Adjust Iterations for finer smoothing.

✅ Tip: Turbosmooth essentially quadruples the polycount of a model with each iteration. Use TurboSmooth sparingly and keep an eye on your poly count.

7️⃣ Shell Modifier 🏗️

• Adds thickness to flat surfaces or planes.
• Adjust Outer & Inner Amount for control.
• Includes beveling options for smooth transitions.

✅ Tip: Great for walls, panels, & hollow objects.

 

8️⃣ ProOptimizer Modifier 📉

• Reduces polygon count while preserving shape.

9️⃣ Chamfer Modifier 🔶

• Rounds off sharp edges for a softer look.
• Adjust Amount & Segments for smoothness.
• Use Minimum Angle to control which edges are affected.

✅ Tip: Set Minimum Angle to 46° to avoid unwanted chamfering.

🔟 Push Modifier ⬆️

• Moves vertices along their normals.
• Can be used to inflate or expand an object.

✅ Tip: Works well for cloth, organic forms, or soft surfaces.
