Convert a Single Tri Poly to Quad

[trevor_thompson4]

I run into this issue a lot when finishing up a low poly model... There's one triangular poly stuck in a corner somewhere. What's the trick to converting it into a quad without disturbing the surrounding polys?

There are a few ways to do it. Without seeing more of your model it's hard to tell what's best but just split one of the edges and then move the vert along the face to make a nice arrangement. If you uploaded the model, I'd split it for you and then you could reverse engineer it.

Did you finally figure out a way to retopologize your model?

Apologies for the delay. Yes, I did figure out how to convert this lone tri, but I got lucky. There was another tri on the other side of my model (also stuck in a corner). So I created an edge between the two. It doesn't look as pretty but it helped convert both polys.

However, I'm still not sure about converting a single tri stuck in a corner. I'm guessing it's one of those case-by-case situations on choosing the best way to convert it into a quad?

Yes, it is case by case and with more experience you'll find it easier. You just extend a loop by cutting through a few more polys and run it to an edge or just bury that cut in a corner that's on a flat area where it won't matter. You really don't 'convert' it to a 4-sided poly, you add cuts so that it has 4 verts instead of 3. You do the same thing for poles (polys that have 5 or more verts), you cut them up to make them 4-sides. Again, it comes with experience how best to cut things up. There are some good videos on Youtube about it.
