Layers in Unity define which GameObjects can interact with different features and one another. They are most commonly used by Cameras to render only a part of the scene, and by Lights to illuminate only parts of the scene. But they can also be used by raycasting to selectively ignore colliders or to create collisions

AltSpace Layers for Unity 2020
Layers is a universal tool inside of Unity and there are some general rules and do’s and do not’s so I encourage further Unity learning. However, I will document what I’ve been able to find on Discord with the help of Andy Wood on the AltSpace Discord server.
Andy was nice of me to use his notes on Discord to populate a guide on using layers specifically for AltSpace. Keep in mind that some of the conventional settings in Unity may need to be tweaked further if you are exporting your Unity world into AltSpace from another project.
Adding layer 15 (and new layers) into Unity
Unity comes with preselected layers. However one of the questions I hear asked is how to add light to avatars and it’s not too difficult to do, but requires adding a new layer and following these rules.
- You can only use layer 15 with realtime lighting for it to work on avatars
- You may consider using a second light in the scene for baking light so you aren’t completely relying on a massive realtime lighting probe for your whole scene.
Andy’s Layer 15 Notes
Andy is a well known Unity world builder on AltSpace has built some beautiful worlds in AltSpaceVR and after having a discussion with him he was happy for me to share his comments shared on Discord to make it easier for people to get started. I encourage people to ask on the official AltSpaceVR Discord server.
As I learn more and collect more information this section will be updated.
