METIS SCAO uses a wavefront control concept that deploys a 2-stage spatial reconstruction where the wavefront
is first reconstructed on an intermediate space we call the virtual DM, and then projected onto the actual control
space. This document addresses the projection of the wavefront estimation on the virtual deformable mirror
(VDM) onto the control modes developed for METIS (Mid-infrared ELT Imager and Spectrograph). We present
a new approach to project onto the control modes using an intermediate regularized projection on the M4 mirror
and then convert to modes. This method enables us to utilise all modes for the projection and control in a stable
manner, achieving high Strehl ratios for a wide range of conditions without the need for complex parameter
tuning.
