hey Rage, very nice, many thanks for the file and the explanation. nice site you sent us to before, especially if one is using fusion as their compositor, nice app, im trying to learn it. i just enrolled in 'advanced CGI and VFX' at one of the institutions here.., my 4 years at uni is over.., and left hanging i went looking for more knowledge.., this time in the CGI world rather than the 'film' world. Fusion is one of the apps we learn. nice co-incidence.
