Hey guys,
How i can do this part?
Should i do shrinkwrap or extrude it from the helmet?
How would you do it?
Short answer is - however you want/know how/comfortable with.
Long answer: they’re separate pieces, so it’s only logical to model them as separate pieces. That doesn’t necessarily mean “from scratch” though (i.e. shrinkwrap). If you already have the base shape of the helmet, you can just duplicate that shape, cut out and extrude those pieces, delete the rest, then separate them. That way you’re “stealing” already existing form and saving work.
