Marvelous Designer vs Seamly2D

Marvelous Designer creates digital garments from editable 2D patterns, sewing, avatar arrangement, and 3D cloth simulation. It is aimed at CG and gaming users, including character artists and entertainment workflows. Version 2026.0 lists a Lacing Tool, 3D Pencil, Toon Shader, glTF and VRM support, and template-based rigging in beta. The LiveSync plugin transfers meshes, materials, skeletal animations, and geometry caches to and from Unreal Engine; USD simulation export is designed for Unreal Engine Chaos Cloth. The maker describes a library of 77 fabric types, with presets that change garment folds and flow in simulation. Listed export formats include FBX, OBJ, Alembic, USD, USDZ, MC, PC2, MDD, LXO, and PNG. Windows and Mac versions require an internet connection; Linux is available to Enterprise customers upon request. The Personal Monthly Subscription costs $39 a month, and the Student Subscription costs $8.25 a month for qualified students. There is no free plan, but a 14-day trial is offered. Basic use requires 16 GB of memory, with 32 GB recommended for smoother operation.

Seamly2D is free, open-source fashion design software for creating garment patterns on Windows, Linux, and MacOS. Its pattern workflow supports adapting earlier designs and working with size charts, made-to-measure data, and converted body scans. The site lists apparel, costumes, athletic wear, pet gear, outdoor products, and upholstery as possible applications. Seamly describes a process extending from design through manufacturing for physical and digital products, and says its software integrates 2D, 3D, and Mixed Reality. A beta process described for 3DLOOK MOBILE TAILOR measurements converts CSV files into Seamly measurement files by email. The download process asks for a name, email, operating system, and intended use before emailing a download link. The download page says Seamly Systems does not sell or share the personal information it holds. A user forum is available for software discussion. Seamly2D includes 2D pattern making and size grading, with SVG listed as an export format.
