Description
This macro allows to quickly and easily set the color and transparency of individual faces, edges, and vertices.
Usage
- Select one or more subobjects.
- Run the macro.
- The standard Qt color dialog opens.
- Select the color.
- Set the transparency by changing the alpha channel (0 = fully opaque, 255 = fully transparent).
- Do one of the following:
- Press the OK button to close the dialog and apply the color and transparency.
- Press the Cancel button to cancel the macro.
- If you have pressed OK and the subobjects belong to more than one object, the color dialog will re-open for the next object.
Notes
- The current color of the first selected subobject of the current object will be the default color in the dialog. The first 2 custom colors will be the default gray for faces, and the default black for edges and points. The default for the alpha channel will be 0 (no transparency).
- You can use any color you like, but you should probably avoid the colors used for selection (default: green) and preselection (default: yellow) indicators.
- The transparency option does not appear to function for edges and points, only for faces.
- A transparent face is still selectable in the 3D view.
- If the interior side of faces appears black and you would prefer to see the face colors, change the Lighting property of the object from One side to Two side on the View tab.
- The Color properties and the Transparency property of an object are global properties. Changing them will override any changes made to individual subobjects.
