Hey Nova, I was thinking about the skeleton layout for those new exo‑suits—got a few geometry tweaks that could make zero‑g fighting smoother. Wanna hear the math?

Here’s the raw data you asked for, no fluff, just bones and numbers: **Bone hierarchy & lengths (in cm)** 1. root – 10 2. spine1 – 15 3. spine2 – 15 4. neck – 5 5. head – 8 6. upperArmL – 30 7. lowerArmL – 25 8. handL – 10 9. upperArmR – 30 10. lowerArmR – 25 11. handR – 10 **Joint rotation limits (degrees)** - spine1: X ±30, Y ±20, Z ±10 - spine2: X ±25, Y ±15, Z ±5 - neck: X ±45, Y ±45, Z ±20 - head: X ±30, Y ±30, Z ±15 - upperArmL/R: X ±90, Y ±45, Z ±30 - lowerArmL/R: X ±135, Y ±20, Z ±5 - handL/R: X ±90, Y ±20, Z ±10 **Skinning weights** (Just a quick template; you’ll need to adjust per mesh vertex) - root covers torso 100% - spine1 covers lower torso 100% - spine2 covers upper torso 100% - neck & head cover skull 100% - upper/lower arm chains each cover their respective limbs 100% - hands cover digits 100% **Interpolation** Use SLERP between quaternions for smooth blending—keep the dot product positive to avoid double‑swing. If you’re doing manual keyframing, stick to quaternion representation to avoid gimbal lock. Run the sims, let me know if any joint misbehaves. If you hit a snag, it’s probably a mis‑aligned rotation axis or a forgotten parent constraint. Happy to debug.

Sounds good, Nova. Keep an eye on the elbow limits first—those are usually the weak spot. Let me know if the swing looks a bit off, and we’ll adjust the weight blend on the forearm. Happy simming.

Will keep the elbow axis locked tight and watch the quaternion blend for any drift. If the weights hiccup, I’ll re‑weight the forearm until the rotation feels mathematically correct. Stay tuned.
