    English subtitles (I used Google translate. Translation is literal):
    0:02 - Polygon model. Joint dividing line
    0:07 - Number of dividing lines at joints. 2 or more required
    0:12 - The vertices at the joints are drawn inward
    0:15 - Example of dividing line
    0:17 - No edge at joint position
    0:18 - Add to 2 edges
    0:26 - There is an edge at the joint position
    0:28 - Add to 3 edges
    0:36 - 2 edges
    0:38 - Change position and angle
    0:58 - Smooth mesh preview
    1:05 - Add edge type again
    1:12 - Smooth mesh preview
    1:19 - This time's dividing line. Smooth preview below
    1:32 - About the inside of the joint:
    1:33 - Especially if you don't include edges at the joint positions,
    1:36 - the upper and lower edge positions from the joint maintain equal distance.
    1:45 - Smooth mesh preview
    1:54 - Smooth mesh preview
    2:03 - Smooth mesh preview
    2:08 - Hand split
    2:25 - Bonus
    2:27 - Posture of holding one's feet
    2:31 - Large bending angles are distributed over multiple joints.
    2:36 - If you bend your thighs forward more than 90°, your buttocks will become thinner, so bend your thighs at about 90°. As a limit, if you bend your lower back and spine from that point forward, you will be less likely to break down.
    2:42 - Masahiro Ushiyama

    THIS... this is the type of information my professors weren't teaching my class. We were taught the basics of Maya, and what retopologizing was, but not how to properly do it. They'd just say "you'll figure it out the more you practice," and then hand us a grade.

    • @NovaTedd

      I think a take that most people don't want to admit is that online game design and modelling classes all around the world are abysmal. Most people aren't taught important lessons and are given disconnected fundamentals that we're supposed to "figure out as we go" I don't really blame the teachers of these topics because they are usually given very little time to explain a lot but it certainly doesn't help students for what it's cost is

    1:22 - Seems a hybrid between 4 and 6 would be best. (counting from the left) - Actually, you kind of do this at 1:34, segmented joint with the topology weighted towards the lower half
    2:17 - Very interesting hand topology.

    • @ba121
      @ba121 11 місяців тому

      Also worth mentioning quaternion rotation is pretty different from standard rotational deform (blender's preserve volume modifier)... is worth looking at... vertices orbit within perfect spheres at a weight of 1... weight between 0-1 interpolate this sphere with spheres that correspond to any other assigned deform bones or the geometric rest position if weights < 1.

    This is amazing, but I have to wonder why there's no collision detection at the surface interactions. Maintaining an approximate constant volume would allow the muscles to expand as the calf/thigh press into each other.
    Even if it still clipped, the deformation and rendering would add a lot of realism.

    The whole point of the video is actually not about 3D Modelling
    It's about memory reduction and how much Low Poly you can push to a model to make it seamless as if it's High Polygons count
    Just for example, NieR Automata 2B's arm is about 2000 Polygons. 2 Arms makes it 4000 Polygons.
    Their level of Optimization must be done in some other way
