I want to have more edge loops in some areas, while having less in other areas. How to you go about that while maintaining good topology? For example, here is a car I'm modeling. I only need to have about 5 edge loops for the hood, but I want more for the fender. The font of the car also requires alo't of edge loops, but I…
Triangles are fine, so long as it gets terminated on a flat/planar area of your model. Same with n-gons. Try it out and see how it sub-divides, you'll find your answer. Experiment. The trick with organic/curved surfaces, such as vehicles, is evenly spaced loops. Once the area becomes flat, you can terminate those loops to…
My second image does have diagonal lines without breaking the flow of quads. You have a diagonal line and then problems with triangles.. and even not enough geometry for the front window shield yet.. (so you have to loop cut again and.. get new problems with triangles..
