Hi
Good news
I have my biceps deforming nicely and shape is nice and smooth also
now I captured geometry of arm-skin with metaballs
where should I proceed with painting weights
on obj level or in geo-sop?
arm skin is deformed but is totally distorted and this ctr-MMB picking of
bones doesnt seem to work either?
there must be some mistake of mine
but I am getting closer to result anyway! :)
Whats the deal on this character workshop-as I wrote a lot of people cant
come to LA on a two week notice but I would be more than willing to buy
pdf's or movies of these events-was anything like this considered as an
option at least?
nice hello from Black Forest-Germany
