To make an object transparent:
- Drag the Flat shader from the Asset browser and drop it on a model in the Viewer window.
- Select Append.
- Adjust the object’s brightness with the Luminosity slider, if desired.
- Choose a form of transparency for the object with the Transparency Type menu.
- Adjust the amount of transparency applied to the object with the Transparency Factor slider.
If there is a texture applied to the object, its Alpha channel is affected. If there is no texture, the object’s material Transparency property is affected.
