Virtual Chem Lab Render settings

Mental ray is the render engine for the project.
In order to create an occlusion pass:
1. create a new render layer with the desire objects in it. Right click on the layer and select Overrides>Create Material Override.
2. Choose mib_amb_occlusion in the Incandescene channel. Make sure the material you are using is white.
3. Render. Composite it on top of the original render in photoshop. (Mutliply)

The following render settings are used: ( in render globals )
Under Quality Tab:
- Sampling Mode: Fixed Sampling 2
- Raytracing: Reflections/Refractions 10
Max Trace Depth 20
Shadows 2
Reflection/Refraction Blur Limit 1

Under Features Tab:
- Secondary Effects: Raytracing

Virtual Chem Lab files

The project is set at :S:/PROJECTS//Virtual Chem Lab/Drafts/Art, you should be able to find the files needed in this project. The physics and physical science lab files are referencing the following files:
Ceiling - /NewWideView//scenes/OtherAssets/Ceiling_for_Wideview_00.mb
Gases - /NewWideView//scenes/Gasses/Gasses.mb
Titrations - /NewWideView//scenes/Titrations/titrate_for_comp_4c.mb
Inorganics - /NewWideView//scenes/Inogranic/Inorganic_no_bottles.mb
Quantum - /NewWideView//scenes/Quantum/Quantum.mb
Mechanics - /Mechanics/MayaAnimation/scenes/MechanicsRef.mb
Density Buoyancy - /Density_Buoyancy/Maya/Scenes (reference only!)/In Progress/density_lab_hazel.mb
Optics - /Production/3D_Maya/Optics/optics_reference1.mb
Calorimetry - /NewWideView//scenes/Calorimetry/Calorimetry.mb
Circuits - /Production/3D_Maya/Circuits/Maya/Scenes (reference only!)/In Progress/Current/Circuitry_Lab_hazel.mb

Density, Optics, Calorimetry and Circuits are independent files which all the assets and props are imported in the files while the rest is referencing some other files in the same project. The cameras on the ceiling, the white board and the lights are either imported or created in the scenes themselves.
