AI_Measurements

This plugin calculates several real world measurements for a character.

Usage

• Make sure the character is in an upright pose. T-Pose is best if available.
• Inside character creation, navigate to Body > Mods > Measurements.
• Click the Refresh button.

Measurements

Height

• Calculated as the distance between the N_Head_top bone and the origin (0,0,0,).
• Adjusted by the Height and Head size sliders under Overall.

Bra Size

Character band and cup sizes.

Notes

• Displays for female characters only.
• An extremely thin chest can result in an extremely large cup size.
• The Direction slider under Chest can have a very large impact on cup size. I generally set it to 0 (or lower) when taking measurements and fix it afterward.

Band Size

• Calculated by finding four points at the bust (front, back, left, and right) and assuming they make an ellipse.
• Adjusted by the Chest Width and Chest Thickness sliders under Upper Body.
• Rounds up to the nearest
  • multiple of 5 when using metric units
  • even integer when not using metric units.

Cup Size

• Determined by the difference between the exact bust and rounded band sizes using the configured region.

Bust

• Calculated as the distance between 6 points:
  • The lats (N_Back_L and N_Back_R),
  • the nipples (cf_J_Mune02_L and cf_J_Mune02_R), and
  • 2 side breast points calculated with dark magic.
• Adjusted by most sliders under Chest (especially Size) and the Shoulder Width and Shoulder Thickness sliders under Upper Body.

Notes

• Displays for female characters only.
• Serious about the dark magic bit. Read the code if you don't believe. Here is my best explanation of it:
  • Take a line between cf_J_Mune02_{L|R} and cf_J_Mune_Nip01_{L|R}.
  • The calculated point will be the same distance from cf_J_Mune02_{L|R} as the line's length.
  • Additionaly, a line between the calculated point and cf_J_Mune02_{L|R} will form a right angle (to the outer side of the breast) with the first line in the plane that contains both lines.
  • Please don't ask me how the math works. I understood it when I wrote the code and promptly forgot it afterward.

Waist

• Calculated by assuming the four waist bones (N_Waist_f, N_Waist_b, N_Waist_L, and N_Waist_R) make an ellipse.
• Adjusted by the Pelvis Width and Pelvis Thickness sliders under Lower Body.

Notes

• The Waist sliders under Upper Body do not affect this measurement. While it would be intuitive, the four waist bones correspond to the Pelvis sliders, not the Waist sliders.

Hips

• Calculated as the distance between the 6 cf_J_Legsk_0x_00 | {1,2,3,5,6,7} ∈ x bones.
• Adjusted by the Hips Width and Hips Thickness sliders under Lower Body.

Notes

• Displays for female characters only.
• Is not currently affected by the Butt slider under Lower Body.

Dick

• Calculated as the distance between cm_J_dan100_00 (base) and cm_J_dan109_00 (tip) bones.
• Adjusted by scaling the cm_J_dan100_00 bone with AIABMX.

Notes

• Displays for male and futa characters only.
• If switch from non-futa to futa, you may have to cycle to a different tab and back for this measurement to be displayed.

Configuration

Use metric units

Whether to use metric units (centimeters) or British units (feet and inches).

Notes

• Defaults to false.
