I followed the tutorial above. I hooked my bezier curve to my armature, but my armature or bezier curve pinches when I move it rather than bend naturally. Is it due to the control points not aligned accurately along the bone segments? I toyed with the resolution, etc, but didn’t seem to affect the pinching at all.

Thank you.

UPDATE: Figured out it was the depth and resolution size. I only tweaked the resolution size which I thought it was still pinching because my depth size was too great. For example, my depth size was 0.20 and resolution was 12. I set my resolution size to 20. So I reduced the depth size to 0.1 while keeping the resolution size to 20, and that was when I saw a great difference. I tweaked the resolution size to see how that changes the shape now, and now I get the criss cross jaggidy look and now it’s occurred that the res size played the role in this.

Still I wonder how MK Graphics got his tube to look super bendy in his tutorial, but this is fine.

Had a quick skim of the tutorial – and see it’s gone a route I had no idea about but saw this in the comments
“For everyone wondering why the curve bends in a weird way when you rotate the bones: When assigning the hooks to the curve points, you need to select the two corresponding handles too! It seems to be a thing for the newer Blender Versions”

Are you just watching this tutorial without any foundational knowledge of rigging? If so then my advice would be to take the Core Rigging course and try and properly understand armatures and bones before you go any further as there’s a lot to it. I’ve just completed it and the first thing I thought was ‘why aren’t you using bendy bones’. I have no idea about the hook modifier. What’s your use case for this? It might be alot easier to just set the curve as you want it manually

You don’t need to use bendy bones for this. What makes you believe so?

As I said I’ve only just completed the core course so I don’t know for sure. It’s what seemed the most obvious solution for the outcome of the tutorial based on my limited knowledge.

That is incorrect. This simulation here deals with bezier curves, not parenting mesh to armature. Bendy bones have no affect on pinching that is done here.

You should definitely experiment after watching tutorials.

Hi Kimberly,

In your file, Select the Curve, switch to Edit Mode, Select all, so you’.ve got this

then press V > Set Handle Type > Automatic, to get this:

I haven’t watched that video, btw. but I guess it must be something like this.
