In Plane-Maker you will see that there are two “glass” lighting modes for instruments – one called “glass” and the other called “glass (translucent)”.
What’s the difference? The difference is how they respond to their lighting rheostat being turned down.
- Glass becomes dim by mixing the RGB colors of the overlays toward black.
- Glass (tranlsucent) becomes dim by mixing the alpha channel of the overlays toward transparent.
Which one do you want? It depends on what you are doing. The rules I suggest are:
- Use “glass” if you are using the layer as a “mask” to block elements behind it.
- Use “glass (translucent) if you are using the layer as an “overlay” to draw on top of other elements.
