In a low-poly game model, is it ever okay to NOT connect vertices and instead just have a poly-face stick into a mesh? Example: An arm connects to the shoulder of a character. You connect the shoulder vertices to the top of the arm vertices. Could it be appropriate to just have the arm stick into the body and not actually…
Also, not welding every vertice to each other can help your workflow a lot. Especially if you're constantly updating it, you can always weld everything together when you finalize the model. Like making a big room for an apartment, and you have all the smaller rooms as just floating faces within that space and not welded…
