Can you explain your way, and which program you are using? Modelling hands with 5 fingers is hard (for the newbies at least). Try starting with 1 thumb and all the other fingers joined, then move on, to 2 fingers then to 5.
These little one line posts are getting on my nerves. If you need to post again
please refer to some problems your having , maybe show a screenshot and
try methods you discussed so that we can narrow problems down and see exactly
what your progress is.
To make a screenshot if you don't want to go through max rendering you'd
have to just push the Print Screen button on your keyboard, it'll burn all
that's onscreen to the clipboard and from there you just ctrl+v it to whatever
photo editing program to crop and adjust as you please.
If you're talking about saving under different formats, render your scene and
then there should be a button in the top left corner where it can output your
image, instead of saving as bmp look for jpg or the likes.
Here what I would do if I modeled. I'd make 3 different boxes, and connect them togethor, that would be the finger. Then I would do the same for the other 3 and 2 boxes for the thumb. Then I'd create connect those and then make a box or hand shaped object and connect it.
