I’m currently following a tutorial on cgcookie about modeling a motorcycle and I’m really curious about the technique he used.
He is modelling the shape of the motorcycle, and apply the subsurf. After that, he use the shrinkwrap modifier to cut specific pieces like lights,… and doesn’t seem to really care about creating triangles.
Even if the topology looks bad, the result is really good. Can it engenders some problems when shading?
As Ricky said, if you’re not planning on bending or deforming the area it’s fine if it looks good.
One thing I’ve found watching a few tutorials is that they’ll do something like cut out the shapes in one lesson, then come back and fix it a lesson or two later.
