HI, I am working on my first retopology of an sculpture I did, I am planning to animate it and even export the character to a game engine, so while working on the loops I had a hard time finding good references about what loops are good and which are not so, after searching for a couple of days decided the best course of action would be start the retopo and use the Human Anatomy to define Muscles, this i my progress so far after a whole day of working on the retopo, but I am not sure about this loops
The Red ones are Open ended (The Loop has 2 ends, aka will go to the Arms and Legs):
This is the one I am more worried about, but I gave it this shape so it could have the shoulder blade deform, but I think I overdid it
The Blue ones are Open at 1 Side (The loop will go to the leg or arm):
I am not so worried bout this ones, but i am still Skeptical bout these
These greens are full Loops they have no end:
I have this the most, but the bend and go to places I am not so sure they should.
Should I do a more simple set of loops?, btw This mess is 2180 Vertex and 4240 Triangles
Also any good references or videos I could use for character Retopology or Topology in General, I’ll be really grateful, thanks in advance
