* With conditional rendering it's possible to execute certain rendering commands based on a buffer value instead of having to rebuild the command buffers. * With conditional rendering it's possible to execute certain rendering commands based on a buffer value instead of having to rebuild the command buffers.
* This example sets up a conditional buffer with one value per glTF part, that is used to toggle visibility of single model parts. * This example sets up a conditional buffer with one value per glTF part, that is used to toggle visibility of single model parts.
