Material Overrides
Synced materials arrive from Revit with their original names and properties. The Materials panel is where you take control of how they look in Blender — without breaking the sync connection. All overrides are non-destructive and you can reset any of them at any time.
Browsing materials
The material browser at the top of the panel shows all materials for the selected document.
- Search — filter by name
- Selected only — show only materials on currently selected objects
Each material row displays icons for any active overrides:
| Icon | Meaning |
|---|---|
| Globe | Global override is active on this material |
| Refresh arrows | A replacement material is active |
| UV-project | UV preview is active |
| UV grid | UV transform or randomize is active |
| Particles | Scatter is active |
Browser actions: Reset (selected material), Reset All, Select linked objects, Copy overrides, Paste overrides.
Screenshot needed: Material browser with override icons visible
Per-material overrides
Select a material in the browser to access its override subsections.
Screenshot needed: Material with multiple override subsections expanded
Ignore Global Override
When enabled, this material is excluded from the document's global override. Use this to protect specific materials from a scene-wide color or appearance change.
Preview UV
Enables a UV preview overlay on objects using this material. Useful for checking UV mapping before committing to an override.
Viewport Appearance
Controls the material's appearance in the Blender viewport (not in renders).
| Field | Description |
|---|---|
| Base Color | Viewport display color |
| Metallic | Metallic value |
| Roughness | Roughness value |
Render Appearance
Controls the material's rendered appearance via the Principled BSDF node.
Requires: Material nodes must be enabled on the material. If they aren't, open the material in Blender's Shader Editor and click Use Nodes.
| Field | Description |
|---|---|
| Base Color | Render color |
| Metallic | Metallic value |
| Roughness | Roughness value |
| Alpha | Opacity |
| Transmission | Transmission (glass/translucency) |
Material Replacement
Replaces this material with any Blender material currently in the scene. The picker shows only materials already present in the file — if the material you want isn't there yet, add it to the scene first. The replacement is applied on top of the synced data and can be reset at any time.
UV
Controls UV mapping for objects using this material.
- UV Projection — enable and choose a mapping type
- Transform — Translate, Scale, Rotation
- Randomize Islands — Variation Seed, Rotation Variation, Offset Variation
Scatter
Scatter uses Revit's surface and placement data to distribute instances of a Blender object or collection across synced geometry — for trees, ground cover, furniture arrangements, and similar repeating elements. It's powered by a custom BSync node group that loads automatically — no manual node setup required.
Note: Scatter is available on any material that has an override. The required node group is loaded silently from the bundled add-on assets the first time it is used.
| Field | Description |
|---|---|
| Source | The Collection or Object whose instances are scattered |
| Pick Instance | How instances are selected from the source — randomly, sequentially, or by other criteria |
| Source Seed | Randomization seed for instance selection. Change this to get a different mix from the same source |
| Density | How many instances are placed per unit of area. Higher values produce denser coverage |
| Slope Limit | Excludes surfaces steeper than this angle from receiving instances — useful for keeping trees off walls |
| Vertical Preference | Biases instance orientation toward vertical (upright). At 0 instances follow the surface normal; at 1 they stand straight up |
| Lean Variation | Adds a random tilt to each instance, so they don't all stand at exactly the same angle |
| Scale Variation | Random scale range applied per instance |
| Distribution Seed | Seed for placement positions. Change this to redistribute instances across the surface |
| Variation Seed | Seed for per-instance variation (scale, lean, etc.) |
| Viewport Amount | Fraction of instances shown in the viewport. Set below 1.0 to improve performance without affecting the final render |
