Okay. I considered asking a question, but with my poor English,
challenging myself might do faster. Watching the video repeatedly, I could get what it means.
And I have a little question.
As known on other’s question the foot IKs are not straight. So manipulating Y Location makes distance between feet increase.
My solution was press G and X to fix axis and input distance of torso moving.
It worked as I expected. But, Y Location Value was not old position plus 0.65. X Location also changed.
So not only Y Location get increased by cycle, X value also continuously decrease or increase.
I know it caused by not being straight.
But I wonder if there is more robust way to do this.
