This tutorial video for the Shifter biped template goes through to fix various controllers that come out the wrong size and shape by default. https://www.youtube.com/watch?v=F1LLaPe9dEM
When creating a new biped, I found myself having to make exactly the same adjustments as are done in the video, repeating the same steps. Would it be possible to tweak the default controllers that get generated so this isn’t necessary?
