The sweater has a clean, quad topology, and is in real-world scale (the length is 57.6 cm). It is single-sided. UVs are laid out to allow for good pattern placement and don't overlap. No subdivision is provided but it can be added without significant texture distortion.
The mesh uses a 2k texture set. Individual maps (colour, roughness, normal, metallic) are available, as well as compound ones (albedo-transparency, metallic-smoothness). Extra maps - Opacity and AO - are also included. Unzip the textures before working with the .blend file.
The .blend file contains 3 meshes with 1 material each. Each mesh is placed in its own collection. If you intend to link a collection to a different file, reset the location first.
The sweater is exported to: Collada, Alembic, FBX, and Wavefront. Please note that the materials might need to be assembled manually from the provided textures when you import the asset into your chosen 3D software.
