07 Deform Tools in Unreal Engine 5 6 Modeling


Session 7 Summary – Deform Tools in UE5.6

🔹 Project Setup

  • Launched Unreal Engine 5.6, created a new project deform_practice.
  • Imported provided maps folder from Patreon zip.
  • Set up a new level with proper lighting using the Environment Light Mixer.

🛠️ Deform Menu Tools

1. Vertex Sculpt

  • Used for organic deformation (non-geometric).
  • Tools include:
    • Move: Pull or push a group of vertices.
    • Smooth: Blends and softens sharp shapes.
    • Smooth Fill: Fills small pits or holes.
    • Grab: Drags mesh parts freely.
  • No increase in triangle count – only vertex repositioning.

2. Dynamic Sculpt

  • Adds new geometry while sculpting (increases triangle count).
  • Example tool: Inflate.
  • Use cautiously – high polycount may crash system.

🌀 Other Deform Tools

3. Smooth

  • Applies global mesh smoothing.
  • Three modes: Iterative, Implicit, Diffusion.

4. Offset

  • Shifts mesh surface outward/inward.
  • Useful for puffing up or flattening objects.

5. Warp

  • Distorts mesh along axes.
  • Warp types: Bend, Flare, Squash.
  • Adjustable via interactive axis gizmo.

6. Lattice

  • Encloses mesh in a 3D control cage (default 5×5×5).
  • Allows soft selection-based distortion using lattice points.

7. Displace

  • Displaces mesh vertices using:
    • Perlin Noise (random organic texture)
    • Random Noise
    • Sine Waves
    • 2D Texture Maps (e.g., black & white foundation layout image)
  • Enables advanced shaping like terrain, dug foundations, etc.

🪑 Practical Sculpting Example

  • Applied subdivision and sculpt on a chair to soften its form.
  • Used offset and smooth to make it resemble a sofa.
  • Renamed to sm_chair_sculpt.

🔄 Transfer Tool (from XForm menu)

  • Replaced existing patterned chairs with the newly sculpted chair using:
    • Harvest Instances
    • Transfer tool to update all instances with the new mesh.

Conclusion

  • Completed the Deform Module.
  • Learned how to digitally sculpt, warp, displace, and transfer geometry efficiently.
  • Next session will cover the Model menu and its components.
