I have a question regarding a specific topology situation. It may be obvious for some, but i've never received an "Official" answer, so i might as well ask. Let's say i wanted to model a circle inside a flat face of a videogame prop. To keep the polycount extremely low i then decide to create an 8 sided circle, like this…
That depends on how the triangles shade or if they create artifacts. Long thin triangles can be problematic for certain types of rendering. If you have even more edges in your circle then they become longer and thinner, so you might add a ring around the circle and gradually step the number of edges down as it radiates…
