MAYA: Efficient Cine-Lighting

As per Jeremy Vickery's Efficient Cine-Lighting Gnomon Masterclass:

MAIN POINTS:

- MIB_AMB_OCCLUSION shader piped into the "ambient.Color" of all shaders
- AO: samples:100, Max_Distance: 5 or 10
- Spotlight Key
- Area lights to simulate bounce in 'hot' areas created by Spotlight Key
- Wide Arealight to simulate window
- Wide area light to bounce back onto the window surface plane
- Good models help tremendously with lighting
- Subdivide edges and convert to subdivision models to help create a tiny light wrap
- Rim on sphere: Use area light, disable "Illuminates by Default", and have it only affect the sphere
- Use color temperature to your advantage, including the AO black and white points
- each light has 'counter' light

- "bleed" lights to soften hard edges from spotlights


TRICKS:
- add 'Glow' to skydome to create post bloom in Maya
- (JWX) better yet would be to render out a specific matte pass and do in post
- overcrank luminosity values on glow channels past "1.0" to simulate blowout from set color, to color temp fade off (bright yellow fades into red, think lightsabers)
