Tweaking individual fixtures
You can change the motors or light sources of individual fixtures by adding those things in Studio
You should use this only for invidual lights or for testing. If you want to add custom models, follow the custom models guide instead
Motors
You can change the motors of a light fixture by adding a folder named Motors inside of its model. GLights uses 3 motors: Pan, Tilt and Gobo, but not all of them might need to be present.
Any motors that need to be present but haven't been added by you will be generated automatically. For example, if you add a custom Tilt motor, but the light needs a Pan motor as well, the Pan motor will be automatically generated, but your Tilt motor will be used.
Light source
You can change the light source by adding a light named Light in the lens if your fixture. You can change its properties and type freely.
Brightness
The Brightness property of your light will be used as an override of the MaxBrightness setting for that one fixture. For example, if you set the Brightness of your light to 10, this one light will be able to reach that brightness, while all others will use the default brightness.
Enabled
You can disable the light if you don't want to see it in Studio. It'll enable itself automatically once the game starts.
Offset and follow spotlights
If you want to offset the light source, you can create an attachment named Light and put your light inside of that attachment. Then you can move the attachment around to offset the light.
If you're customising lights with follow functionality (washes or heads), you must create the attachment.
