I'm thinking about getting some 1-2" or so diving helmets
printed out to give out at GDC. I haven't printed anything before so I have some qs:
1. I understand the mesh has to be water tight, but does it have to be completely merged together as well? Or in other words, can the mesh be made of of multiple separate objects as long as they are each water tight, or does it have to be one solid shell?
2. Any helpful tips/tutorials/etc for merging everything together and removing holes?
3. I would like to use the highpoly for this, but maybe that is dumb as its a bunch of meshes with holes, while the lowpoly is pretty much water tight already (would need some work). Thoughts?
4. Anything else I need to be concerned with?
