Tutorial 4: Quality Settings and Performance
Mesh resolution is the most important tradeoff in Mesh Sculptor: higher quality captures finer detail but takes longer to regenerate. In this tutorial you will learn how the quality system works, when to use each preset, and how to optimize your workflow for both speed and detail.
What you'll learn
- What U and V resolution mean for the mesh
- The four quality presets and their triangle counts
- How quality interacts with effects and cross-sections
- Performance optimization techniques
- How export quality differs from preview quality
Prerequisites
- Completion of Mesh Sculptor Tutorials 1–3.
- A Mesh Sculptor project with a shaped profile.
Step 1: Understand U and V resolution
The mesh is a grid of vertices organized along two axes:
- U (circumferential) — how many segments wrap around the cross-section. More U segments = smoother curves around the perimeter.
- V (vertical) — how many segments stack from bottom to top. More V segments = smoother vertical transitions and finer effect detail along the height.
Step 1
Visualize the grid
Switch to Draft quality and look closely at the mesh in the 3D viewport. You may see subtle faceting — this is the grid. Each small quad on the mesh surface is one grid cell defined by adjacent U and V segments.
Step 2: The four quality presets
Step 2
Compare quality levels
Switch between each quality preset and observe the mesh:
| Preset | Segments | Approx. Triangles | Use Case |
|---|---|---|---|
| Draft | 128 × 128 | ~33K | Fast iteration, rough previews |
| Standard | 256 × 256 | ~131K | Design work, parameter tuning |
| High | 512 × 512 | ~524K | Final preview, detail verification |
| Ultra | 1024 × 512 | ~1M | Export, large prints, very fine effects |
The triangle count estimate is shown next to the quality selector. This is the approximate number of triangles in the exported mesh.
Step 3: Quality and regeneration speed
Step 3
Time the regeneration
Add a simple effect (like Surface Waves) and switch between quality levels. Notice the regeneration time:
- Draft — regenerates in under a second. Perfect for rapid iteration.
- Standard — 1–3 seconds. Good for detailed design work.
- High — 3–10 seconds. Use when you need to verify fine detail.
- Ultra — 10+ seconds. Use only for final export.
Step 4: How quality affects effects
Effects displace individual vertices. The more vertices (higher quality), the finer the detail an effect can produce:
Step 4
Compare an effect at Draft vs High
Add a Knurling effect with a fine pattern (high frequency). Switch between Draft and High quality:
- At Draft, the knurling pattern may look blocky or aliased because there aren't enough vertices to represent the fine pattern.
- At High, the same knurling settings produce crisp, well-defined diamond patterns.
This means that some effects need higher quality to look their best. If an effect looks rough at Draft, try Standard before changing effect parameters.
Step 5: Quality and cross-section resolution
Custom Bézier and Koch cross-sections automatically multiply the U resolution to capture their complexity:
Step 5
Observe cross-section scaling
- Create a Custom cross-section with many points and tight curves
The resolution multiplier adds on top of the quality preset's U segments. At Standard quality (256 U) with 2x resolution, the circumferential resolution is 512 segments.
Koch snowflakes also auto-scale: higher iteration counts automatically increase the circumferential resolution to capture the fractal detail.
Step 6: The auto-update workflow
Step 6
Understand auto-update vs manual update
Depending on your settings, the mesh either regenerates automatically when you change parameters, or waits for you to click an UPDATE button:
- Auto-update — convenient but can slow you down at high quality levels, because every slider drag triggers a regeneration.
- Manual update — lets you make multiple changes, then regenerate once. Better for high-quality preview work.
Step 7: Export quality vs preview quality
Step 7
Export at a different quality
When you export your design, the mesh can be regenerated at a higher quality than your preview setting. This means you can:
1. Design at Draft or Standard for speed
2. Export at High or Ultra for maximum detail in the final STL file
The export dialog lets you choose the quality level for the exported mesh.
This is the recommended workflow: iterate fast, export high.
Step 8: When to use each quality level
| Activity | Recommended Quality |
|---|---|
| Exploring profile shapes and cross-sections | Draft |
| Adding and adjusting effects | Standard |
| Fine-tuning effect parameters | Standard or High |
| Verifying final design before export | High |
| Exporting for printing | High or Ultra |
| Very large prints (300+ mm) with fine effects | Ultra |
Outcome
You now understand the quality system and how to optimize your workflow:
- U × V resolution determines mesh density and detail
- Draft for speed, Ultra for final quality
- Effects look better at higher quality — check before adjusting effect parameters
- Cross-section Resolution multiplier adds detail for custom shapes
- Export at a higher quality than your preview for the best of both worlds
