Block out the jacket by tracing exterior patterns with the polygon tool, refine curves with curve points, and apply symmetry to assemble the main body in Marvelous Designer.

Adjust the opposite sleeve in Marvelous Designer to reduce fabric bunching, then mirror the edit, expand by about 25, and connect sewing lines for a jacket-like, properly sewn sleeve.

Export the jacket from Marvelous Designer to ZBrush by fixing normals, unifying stitches, removing extra geometry, and exporting jackets and avatars as quads for accurate sculpting.

Continually refine the jacket in ZBrush by applying stitch and Damien standard brushes, adding shoulder padding, zippers, and subtle folds, using symmetry and subdivision adjustments.

Fix the jacket interior by correcting black-face geometry, deleting problematic sections, and using clay with a black-face mask to prevent skin showing, while using lasso to keep geometry clean.

Apply advanced lighting and environment setups in KeyShot to render jackets with ambient occlusion, multiple camera angles, and alpha backgrounds for seamless compositing.

Import a custom avatar into Marvelous Designer using the base male model, then export and reimport to test a tank top jacket with a single poly group and correct scale.
