Preparing the model for UV layout

…In order to make a color 3D print, we need to create a texture map for the colors.…As it is now, the color is tied to…the vertices of the mesh instead of a texture map.…Now, before we can generate the texture map, it's usually a good idea to break…up the model into a bunch of polygroups from which we can generate the UV map.…Now, this is because UV Master can…get confused when laying out very complex shapes.…And the more polygroups we make, the simpler it will be.…

Maybe it'll be better if I just show you.…So, let's hit Shift+F to see the polygroups.…Right now this model is just one big polygroup.…If UV Master tries to lay out the UVs for…this single polygroup at once, it could be a big disaster.…So, let's try to break it into different polygroups.…Let's hit Shift+F to get out of wire frame mode.…And what I want to do is just draw a selection over part of the model.…So, let's try to separate the inside and the outside of the model.…So, I'm just going to mask off that part right there.…And hit Ctrl+W to turn that masked section into a new polygroup.…
