@William Vaughan Thank you! This is the best work so far.

@Nikita Kapustin Thank you for your advice. I've been debating whether to learn Octane for a while, but I've decided to focus on Cycles. I appreciate your time.

Due to my aging eyesight and the fact that I'm not a native English speaker, I find it very difficult to read. It would be easier to read if there was more contrast between the background color and the text color.

Hello William. This is my experience from when I first started using Plasticity until now. There are commands that yield different results depending on whether I'm selecting a closed curve or the region inside it, and it took me some time to notice this. Even now, I occasionally make mistakes unintentionally. One of the first functions I was eager to master was the use of the Pivot. It's now an integral function that I rely on for tasks such as moving and rotating. Until I discovered the Slice Down feature of the Mirror, I was manually cutting off half and then mirroring it. I had been struggling with the Draft function to tilt faces diagonally, but it was only recently that I discovered the easier methods of rotating faces or moving edges.

This is precisely the information I have been seeking. I had assumed there would be established methods for SubD modeling, and have searched for them, yet I couldn't find any comprehensive sources. I was on the verge of giving up on modeling in Blender, but now it seems I can proceed further. I am truly grateful for your assistance.

@Enrico Grotto Thank you very much. I'm extremely happy because creating the Facebook robot was the most challenging part.

@William Vaughan Thank you so much. The Youtube Robot is the first robot in the Cutebot Family, I also have a strong emotional attachment to it.
