[Feature Request] Object Material

[leoyakxi]

Material will greatly enhance how we communicate state change and interactive area in the prototype.

The spotlight examples are using half transparent PNG as fog and acrylic. Using outlined PNG as spatial outline.

It would be great to have material options built in.

Here are some materials that are simple but enables a lot of potential:
- lit (Standard)
- unlit (UI Text)
- acrylic (UI List)
- fog (area of focus)
- border (hologram, selection)
- masking (transition)
- LED Light (reward, feedback)

Comment below for material that you think might be good as well~
