@duerer the Mesh Modeling Bootcamp by @jlampel really helped me wrap my head around topology better. I went from bad topology to not as bad to decent. I still make mistakes a lot but doing that learning flow really helped. The other tidbit from @theluthier that I am terrible at is: get the main outside edges all sorted then sort the detailed extrusions and give them good holding edges that take all of the push and pull from a Sub-D mod and then work your way connecting the two and figuring out the n-gons and poles on fairly flat areas. Hopefully that makes sense. Watching his live stream working out the rear digger arm and details was very helpful. I want to go back and watch that a few more times because I still forget to do that.
Now granted you’re and Spikey’s job is an extreme situation where very little geometry isn’t going to be a challenge. I almost wonder if modeling things on a flat plane and then wrapping them into circles and joining them would maybe be a clever way of working with cylindrical objects??? Or maybe I am just rambling? @spikeyxxx has really good ideas when it comes to this stuff. I want to see more WIP pictures Spikey!
