Intro to 3d Coat: [UV Unwrap and Baking] 

Thanks, and yeah even nowadays (this video is quite old) I find myself over-explaining things or not getting to the point. It infuriates me when I see it in other tutorials but I guess I never realised how hard it was to "talk and do" at the same time. I'm in the process of editing and uploading a new 3d coat series, so maybe you can see if I've improved at all, or gotten worse!

You're very welcome!

Thanks! As time moves on I'll be teaching more and more complex things in 3d coat, so I hope those prove beneficial too.

Yeah, the sculpt mesh and retopo/poly mesh are two completely separate things. So if you're needing to make changes to the sculpt after you've done your bake, then often you'll need to re-bake*. This isn't a 3d coat thing, it's a 3d thing. If anything, 3d coat make this entire pipeline so easy that going back and making changes is amazing compared to literally any other program out there today. As an example, A guy I work with does his sculpting in Zbrush, low poly in 3ds max (but using decimated mesh in zbrush to help), UV's in 3ds max, and baking in substance painter (which for decent bakes often requires an additional "cage mesh" that you have to export separately). When he has to make changes to something after a bake, you can imagine how much of a hassle this is. *It is worth noting, if you're not making any major changes or shape tweaks, and maybe just forgot to include some surface level detail or something. You can always paint normal map information in the paint room (after the bake). All your bake data is converted into a normal map anyway so if you're just missing some bumps/lumps or a few screws/bolts and things like that, just paint it!
