If no format is specified, the target will be created using the backbuffer's image format. This command should not be called until EfxCam_SetToImage has been used to setup the EfxCam's primary render target.
Parameters
EfxCamID

ID of the EfxCam
TargetIndex
INTEGER
Value ranging from 1 to 3 indicating the MRT target's index
