File Formats & Spec

Meshes

Inputs

• 2D concept art (JPG, PNG)

  • Flat reference images are the starting point for 3D model generation.

• Basic meshes / blockouts (FBX)

  • If provided, these help guide topology, scale, and proportions.

Outputs

• Mesh formats:

  • FBX – recommended for most game engines and pipelines.

  • OBJ – universal format for geometry.

  • GLB / GLTF – lightweight for previews and web compatibility.

  • USD – for pipelines using Pixar’s Universal Scene Description.

  • MTL – material library files (when exporting alongside OBJ).

• Topology:

  • Optimized clean quad-based meshes by default.

    • Triangulated topology can be enabled for game engines or workflows that require it.

  • Targeted polycount depending on client needs (e.g., real-time game assets vs. marketing).

• UVs:

  • Properly unwrapped for texturing.

  • Non-overlapping UVs for PBR workflows.

    • Stacked UVs can be enabled for optimization.

Textures

Inputs

• Optional reference textures (e.g., color palettes, material swatches).

• Style guides or art bibles to match studio-specific look.

Outputs

• Available maps:

  • Base Color (albedo)

  • Normal Map

  • Roughness

  • Metallic

  • Ambient Occlusion

• Formats: PNG or TGA

• Resolutions:

  • Standard: 2K (2048x2048)

  • Higher/lower resolutions available depending on client request.

---

Rigs

Inputs

• If rigging references are available (e.g., skeleton structure, control schemes), these can be provided.

• For characters: reference on required bone hierarchy (Humanoid, Quadruped, etc.).

• Description of how rig will be animated.

Outputs

• Skeletons:

  • Humanoid rigs compatible with Unity and Unreal humanoid skeleton standards.

  • Custom rigs available for stylized/non-standard characters.

• Formats: FBX with embedded rig data.

• Skinning: Proper weight painting for deformation.

Delivery Notes

• Final Asset: Delivered in chosen mesh + texture + rig format, production-ready.

• Custom Pipelines: For studios with proprietary requirements, Kaedim’s artist team can adapt exports.

Best practice: Always specify your required output formats (mesh, texture maps, rigging setup) during the kickoff, so Kaedim can tailor the pipeline.
