The best way to create branches for a tree.

Hi. I’m trying to create a tree. There are two approaches I can take when creating branches:

  1. Use the simplest shape, like a square. So I’ll get less vertex, but I’ll get a lot of transparent pixels that will have to be discarded when rendering.
  2. Use complicated shape with outlining around the contour. So it’ll significantly reduce the number of transparent pixels, but greatly increase pixels, which is especially significant when wind is used in a scene.

Do you think it’s worth outlining the branches or is the processing of transparent pixels very fast and not worth it?
