Hoodie Production Tutorial
I. Style Analysis
The first step in modeling is to observe the object:
Through observation, you can find that the hoodie fabric has good thickness. The cuffs and hem lie relatively flat, with natural wrinkles on the hem. The neckline features eyelets, and stitching texture is required around the pocket openings.
For production, we recommend making the main body first. Sew the pockets and hood drawcords last. Topstitching and eyelets should be added only after the main panel fit is finalized with no further adjustments needed.
II. Arrange pattern pieces
Step 2: Adjust the position properly when placing the garment pattern pieces. Wrap the pattern pieces around the model. This prevents clipping after simulating the sewing result.

III.Sewing pattern pieces
Step 3: When sewing, make sure all stitching lines follow a consistent direction. In the 3D viewport, stitching lines should run parallel without overlapping.
Complete sewing for the main body first (all pattern pieces except pockets and hood drawcords). Note that the panel above the back neckline needs to be sewn onto the inner side of the back neck.
Back Neck Panel Sewing Direction
You may freeze all other pattern pieces first, then sew and simulate the small back neck panel separately. This fixes the small panel in place in advance so it won’t shift during subsequent simulation.
Once the main body is fully sewn, proceed to sew the pockets and hood drawcords. Note that do not stitch the side openings of the pockets.

IV. Pattern Piece simulation
Step 4:
- Harden all pattern pieces before starting simulation. This makes it easier to adjust the pieces later and prevents them from moving around excessively during sewing simulation.
- Change the avatar’s hairstyle to "Bald". For garments with hoods, switch to short hair to better display the simulation results.
After all pattern pieces are sewn, keep the hood hardened. Slowly pull it down to the back of the avatar’s head, then remove the hardening. This allows the hood to be adjusted easily while maintaining a better shape.

V. Fine-tuning Pattern Pieces
Once the basic simulation of the full garment is finished, adjust the fabric properties, including the fabric physical properties, internal line folding and line elasticity.
- Physical properties consist of stretch and bending parameters. The higher the stretch value, the less stretchable the fabric. The higher the bending value, the stiffer the fabric.
- Internal line folding creates simulated thickness and stitching appearance at pocket openings from the front view. A larger fold angle makes the pattern pieces on both sides of the internal line fold further inward.
- Line elasticity is used to generate natural fabric wrinkles.
Select the lines using the Edit Pattern tool, and moderately increase the fold angle in the property editor viewport.
Use Edit Pattern tool to select lines, turn on elasticity in property editor, adjust elasticity value for natural wrinkles.
Import matched fabric to pattern pieces; fabric properties will update automatically. The garment’s stretch and bending performance will conform to the simulated state of the imported fabric.
VI. Points to Note for In-depth Refinement
- Rib fabric appears neat and rigid. Determine whether to keep it hardened throughout simulation.
- Freeze the hood and hood drawcords while adjusting other pattern pieces to preserve their shape.
- Add topstitching and eyelet textures only after all adjustments are complete; this allows you to view the final effect more intuitively.
