// - Two bits are needed here (0x3) so that the ReflectionProbeStencilPass can use "Less" on its stencil test to

|
// properly handle the DecrSat on the FrontFace stencil operation depth-fail.
|
|
// - The ReflectionProbeStencilPass pass may overwrite other bits in the stencil buffer, depending on the amount of
|
|
// reflection probe volume nesting in the content.
|
|
// - New stencil bits for other purposes should be added to the most signficant bits and masked out of the Reflection passes.
|
|
// This is necessary to allow the most amount of bits to be used by the ReflectionProbeStencilPass for nested probe volumes.
|
|
// - The Reflection passes currently use 0x7F for the ReadMask and WriteMask to exclude the UseDiffuseGIPass stencil bit (see below).
|
|
// If other stencil bits are added then these masks will need to be updated.
