How to use support, seam, and fuzzy skin painting
How to use support, seam, and fuzzy skin painting
Support, fuzzy skin, and seam painting let you control specific regions of a model instead of applying a setting to the whole print. Use this article for the Cloud Slicer paint panels and brush controls for these three non-color paint tools.
What each tool does
The Cloud Slicer includes these non-color paint modes:
Tool | What it controls |
|---|---|
Support painting | Where supports should be forced or blocked |
Fuzzy skin painting | Where fuzzy skin texture should be applied |
Seam painting | Where seams should be encouraged or avoided |
Before you start
Select one unlocked model before entering paint mode.
The paint buttons are disabled when no model is selected, when multiple objects are selected, or when the selected object is locked.
Enter a paint mode
- Select the model you want to edit.
- Click Support painting, Seam painting, or Fuzzy skin painting in the top toolbar.
- Use the paint panel to choose mode and brush options.
The slicer isolates the selected model while painting, then restores the scene when you exit.
Support painting
Support painting has two modes:
- Enforcer marks areas where support should be forced
- Blocker marks areas where support should be avoided
Use enforcers on small overhangs or details where automatic supports are too conservative. Use blockers on visible surfaces, text, holes, or features where support removal would be difficult.
Fuzzy skin painting
Fuzzy skin painting applies fuzzy skin to painted regions. It does not show an enforcer/blocker switch in the paint panel.
Use it for grips, handles, matte texture areas, or surfaces where a rougher finish helps hide layer lines.
The exact texture strength comes from the slicer settings for fuzzy skin. Painting controls where the effect is applied.
Seam painting
Seam painting also uses enforcer and blocker modes:
- Enforcer tells the slicer where seams may be placed
- Blocker tells the slicer where seams should be avoided
Use seam enforcers on corners, back sides, or less visible edges. Use blockers on front-facing surfaces where seam marks would stand out.
Seam painting supports vertical direction lock, which helps keep the stroke aligned.
Choose a brush
All three tools use the same brush types:
Brush | Use it for |
|---|---|
Sphere | General painting |
Circle | Front-facing surface painting |
Triangle | Precise triangle edits |
Fill | Filling connected regions |
For fill, use Smart fill angle to control how far the fill spreads across connected surfaces.
Paint, erase, and clear
Use these controls while painting:
- Left click paints
- Shift + left click erases
- Ctrl + scroll changes brush size
- Clear removes the current paint type from the selected model
The Clear button only clears the active paint type. Clearing support paint does not clear seam, fuzzy skin, or color paint.
