Maya to Substance workflow

The Maya to Substance workflow typically involves preparing a 3D model in Autodesk Maya and exporting it to Adobe Substance (e.g., Painter or Designer) for texturing. Here's a step-by-step guide:

1. Modeling in Maya

• Create your model: Ensure your model is clean, with proper geometry (quads preferred for most workflows).
• UV Mapping:
  • Unwrap the UVs to ensure a clean, non-overlapping UV layout.
  • Use Maya's UV Editor for adjustments.
  • Avoid stretching and ensure the UV shells are proportional to the object's scale.
• Freeze Transformations: Go to Modify > Freeze Transformations to reset object transformations.
• Delete History: Use Edit > Delete by Type > History to clean the scene of unnecessary data.

2. Preparing for Export

• Apply Materials:
  • Assign simple materials in Maya (e.g., Lambert or Blinn) to identify parts of your model.
  • Use separate materials for different textures you want to apply in Substance Painter.
• Set Naming Conventions:
  • Name meshes and materials clearly (e.g., Body_Mesh, Metal_Material).
• Triangulate the Mesh (optional): Some workflows prefer to triangulate the mesh to avoid unexpected issues in Substance Painter. Use Mesh > Triangulate if needed.
• Export as FBX or OBJ:
  • Use File > Export Selection and choose FBX or OBJ format.
  • In the export settings:
    • Enable "Smoothing Groups."
    • Include "Materials" and "Embed Media" (optional).

3. Importing to Substance Painter

• New Project:
  • Open Substance Painter and create a new project.
  • Select your exported file (FBX or OBJ).
  • Configure texture settings (e.g., resolution, bit depth).
• Bake Mesh Maps:
  • Go to Texture Set Settings > Bake Mesh Maps.
  • Bake maps like Normal, Ambient Occlusion, Curvature, and World Space Normal.
  • Use a high-poly model for baking if applicable (select the high-poly mesh during the baking process).
• Apply Textures:
  • Use Substance Painter's tools to paint and apply materials, smart materials, and masks.

4. Export Textures from Substance Painter

• Export Settings:
  • Go to File > Export Textures.
  • Select the appropriate preset for your target renderer (e.g., Arnold, V-Ray, or Unity).
  • Set texture resolution and output format (e.g., PNG or EXR).
• Export Path:
  • Choose a location for your exported textures.

5. Importing Textures Back into Maya

• Apply Textures:
  • Import the textures (Base Color, Normal Map, Roughness, etc.) into Maya.
  • Use the Hypershade editor to create a material (e.g., aiStandardSurface for Arnold).
  • Connect the textures to the corresponding material attributes:
    • Base Color → Base Color
    • Normal → Bump Mapping (set to Tangent Space Normals)
    • Roughness → Specular Roughness
• Adjust Lighting:
  • Set up proper lighting in Maya for realistic rendering.

6. Rendering in Maya

• Use a renderer like Arnold for final output.
• Test render settings for quality and performance.
• Apply additional tweaks if necessary (e.g., HDRI environment for lighting).

Tips for a Smooth Workflow

• Always check for scale consistency between Maya and Substance.
• Use Substance’s default UV Checker to ensure UVs are clean.
• Keep a clean project folder structure to avoid missing textures or files.
• Save versions of your files at key stages to avoid losing progress.
