Checking the model's integrity

- Before we take our retopologized model…back into sculpting, it's important…that we first do a pretty good check…to make sure the model is sound.…If you don't have a good, solid topology,…if there are errors in the mesh,…it's going to cause problems.…In the first instance,…it may make it difficult…to get a good result by re-projecting the mesh…onto the sculpted model.…If, however, sometimes that may work,…and you go ahead about your business,…as if everything is going fine.…

And then later on, after much work and effort,…and sweat and anguish,…you get all the detail in the model that you want…and you finally want to bake that out into…displacement maps, and tunnel maps,…or whatever maps you want,…and you go to hit the bake command,…and you find you just get a bunch of junk,…and that can be really frustrating.…So we need to do everything we can…to make sure that doesn't happen.…So once we got what we think is a pretty good model,…and I'll tell you…that I've intentionally put a few problems…in it just so we can go ahead,…
