You can export your work from Mudbox and quickly import it into Maya using File > Send to Maya. Send to Maya exports from Mudbox using the Autodesk® FBX® file format. For more information, see Export using FBX.
Don’t send paint layers: Exports no paint layers. The model will appear in Maya with the default shading material.
Flatten the paint layers in each channel: Exports one paint layer for each existing channel type (Diffuse, Bump, Gloss, and so on). If a paint channel contains multiple layers, the layers are collapsed to a single layer for exporting.
Send paint layers separately: Exports all paint layers on a model combined into a layered shading material. The appearance of paint layers in Maya can differ from the original appearance in Mudbox based on how layer blend modes are handled by each application. Normal and displacement maps cannot be combined into a layered material, so they are collapsed into one layer within their associated channel before export. For more information on where paint layers are saved, see Export using FBX and FBX.
Flatten sculpt layers before sending: Only the current subdivision level is exported. Display the subdivision level you want before sending to the other application. Any sculpt layers not locked to the current subdivision level are baked into the resulting mesh during export. The current subdivision level becomes the base level for the exported mesh.
Export sculpt layers on current mesh level as blendshapes: Preserves the separate sculpt layers for export. Only sculpt layers associated with the current subdivision level are exported as blend shape/morph targets in the FBX file.
Mudbox launches Maya (if Maya is installed) and imports the file. If Maya is already running, a prompt asks whether to save your scene before importing the Mudbox file. If Maya does not launch, see Troubleshoot file import and export.
