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.
