Passes are contained within an OgreMax Technique:

Color

• Color Write - Indicates whether color writes are enabled.

• Ambient Color - Ambient color.
• Alpha - Ambient color alpha.
• Use Vertex Color - Indicates whether the vertex colors should be used instead of the ambient color.

• Diffuse Color - Diffuse color.
• Alpha - Diffuse color alpha.
• Use Vertex Color - Indicates whether the vertex colors should be used instead of the diffuse color.

• Specular Color - Specular color.
• Alpha - Specular color alpha.
• Use Vertex Color - Indicates whether the vertex colors should be used instead of the specular color.

• Emissive Color - Emissive color.
• Alpha - Emissive color alpha.
• Use Vertex Color - Indicates whether the vertex colors should be used instead of the emissive color.

• Shininess - The surface shininess. Lower values result in a duller surface, higher values result in the shine being more sharply defined.

Rendering

• Allow Mode Override - Indicates whether the primitive type can be can be downgraded by the camera, if the camera itself is set to a lower polygon mode.
• Polygon Mode - The mode used when rendering polygons.
• Shading - The type of shading performed with lighting.
• Hardware/Software Cull - Culling modes used to discard back or front-facing primitives.
• Normalize Normals - Indicates whether vertex normals should be normalized. If not checked, normals are assumed to be normalized already.
• Transparent Sorting - Indicates whether transparent textures should be sorted by depth.
• Force Transparent Sorting - Forces transparent sorting, regardless of the depth buffer write and blending settings.

Blending

• Source/Destination Blend - Blending factors.

Point Sprites

• Point Sprites - Indicates whether point sprites are used. Point sprites can be thought of as per-vertex billboards.
• Point Size - The point sprite size.
• Min/Max Size - The minimum and maximum point sprite sizes.

• Attenuate - Indicates whether the point sprite sizes should be be attenuated by their distance from the camera.
• Attenuated Min/Max Size - The minimum and maximum point sprite sizes.
• Constant/Linear/Quadric - Attenuation factors.

Fog

• Override - Indicates whether the material's fog settings should override the scene's fog settings.
• Mode - The fog mode.
• Color - The fog color.
• Start/End - The fog range.
• Density - The fog density.

Depth/Alpha

• Depth Check - Indicates whether depth checking is enabled.
• Depth Write - Indicates whether depth writes are enabled.
• Alpha to Coverage - Indicates whether the pass will use 'alpha to coverage', a way to multisample alpha texture edges so they blend more seamlessly with the background.
• Depth Bias/Slope Bias - Biases used to offset written depth values.
• Iteration Depth Bias - An additional bias derived from the number of times the pass has been iterated.
• Depth Function - Function used to accept or reject rendered pixels and their depth values.

• Alpha Rejection - Function used to accept or reject rendered pixels and their alpha values.
• Alpha Rejection Value - A reference alpha value used by some alpha functions.

Lighting/Iteration

• Lighting - Indicates whether lighting is enabled.
• Scissor - Indicates whether rendering will be limited to a screen-space scissor rectangle representing the coverage of the light(s) in use, derived from their attenuation ranges.
• Use Clip Planes - Indicates whether triangle setup will be limited to a clipping volume covered by the light. Directional lights are ignored, point lights clip to a cube the size of the attenuation range or the light, and spotlights clip to a pyramid bounding the spotlight angle and attenuation range.
• Illum. Stage - Indicates which illumination stage during rendering that the pass applies to.
• Start Light - During rendering, lights are collected for each object. This index indicates where to start in that collection.
• Max Lights - The maximum number of lights supported by the pass.

• Iterate - Indicates.the type of iteration to perform when rendering with the pass:
  • Once - The default behavior.
  • Per Light - The pass is executed once for each light.
  • # Iterations - The pass is executed the specified number of times:
    • # Iterations - The number of times to iterate.
    • Lights - The method for passing in lights during each iteration.
      • All Lights - All lights are passed into the pass on each iteration.
      • Per Light - The pass is executed the specified number of times for each light.
      • Per # Lights - The pass is executed the specified number of times, with each iteration using the specified number of lights.
        • # Lights - The number of lights to use for each iteration.

• Supported Light Type - The type of light supported by the pass and its iterations.
