* \brief Enable/Disable alpha test for this material
|
|
*
|
|
* When enabled, all objects using this material will be rendered using alpha testing,
|
|
* rejecting pixels if their alpha component is under a defined threshold.
|
|
* This allows some kind of transparency with a much cheaper cost as it doesn't prevent any optimization (as deferred rendering or batching).
|
|
*
|
|
* \param alphaTest Defines if this material will use alpha testing
|
|
*
|
|
* \remark Invalidates the pipeline
|
|
*
|
|
* \see IsAlphaTestEnabled
|
|
* \see SetAlphaThreshold
