3DMM facial model courses

Hey guys, this might be a bit off-topic but I’m interested in applying 3DMM, BFM or LYHM for 3D dense face alignment/reconstruction in personal projects

For some reason I can’t find any practical hands-on courses anywhere (neither paid, nor free) to learn internal 3DMM details (geometry, albedo, SH, illumination, etc.)

Are there any resources you used for learning it? Also interested in paying for a private teaching session (or sessions)
