Feature Overview
With USD, a graphics standard file format, you can increase collaboration productivity with a variety of 3D software
You can export clothing, avatars, and accessories with meshes and materials from Marvelous Designer as USD files. You can also import USD files created in other 3D software packages into Marvelous Designer.
Import USD
You can import an USD file as an avatar, a trim, or a scene/prop type. Cloth and avatar animations can also be exported/imported. (ver. 2024.1)
Steps
Follow the indicated guideline below.
Location
Main Menu ▶ File ▶ Import ▶ USD
Main Menu ▶ File ▶ Import (Add)▶ USD
USD Layer Window ▶ Import
Drag & drop an USD file on to the software
Setting - Import USD Dialog
|
Load Type |
Open | All existing objects will be removed, leaving the imported file only. |
| Add | Add an object, keeping the existing objects. | |
|
Object Type |
Avatar |
Import an USD file as an Avatar type. |
| Trim |
Import an USD file as a Trim type. - The object will pass through the clothing while Simulation is on, as the Trim type cannot collide with clothing. - Select an trim object and toggle on the Glue icon on the gizmo to attach the object to clothing. |
|
| Scenes & Props | When importing an object as Scenes & Props, the object will pass through the clothing while Simulation is on, as the Scenes & Props type do not have Collision. | |
|
Auto Create Fitting Suit |
A Fitting Suit is automatically created in the import process. | |
|
Scale |
Scale | Set the unit of scale. |
| % | Adjust the scale in percentage. | |
| Axis Conversion (ver.2024.1) | X, Y(Up), Z |
Using Axis Conversion, you can change the orientation of the imported mesh. Select the up-axis used in the application where the file was imported from. Marvelous Designer will compare the up-axis of the incoming file and apply conversion if necessary. ※ Note : In Marvelous Designer, the Y axis is the up-axis. |
| Invert | Invert the selected axis. | |
|
Translation |
Align Bottom to Ground |
When an object is placed below the ground, toggle on Align Bottom to Ground check-box to place the object imported above ground. |
※ Note (ver. 2024.1):
- It is recommended that the Animation Layer name not be changed.
- When importing an Avatar that is a USD file format, Motion files (.MTN) cannot be applied to that avatar because it is not the default skeletal avatar type supported by Marvelous Designer.
- If multiple skeletal animations (SkelAnimation) are loaded into the animation window, the upper most animation is played in the 3D Space.
End Result
The USD file is successfully imported into the software you set.
A list of layers for the imported file can be found on the USD Layer window.
- If USD Layer window is not visible in the workspace, it will appear in a new window as a pop-up.
Export USD
You can export clothing, avatars or trims as an USD file. Cloth and avatar animations can also be exported. (ver. 2024.1)

* When exporting garment using Export to USD Layer, the exported output will differ depending on the 3D Garment Rendering Style state. If the 3D garment appears in Thick Textured Surface, it will be exported with thickness.
End Result
The USD file is successfully exported as you set it.
* When saving the project file (*.zprj), the imported USD Layer and file information will be saved altogether.
- When opening this file, if the USD file path is missing, you can either create new or ignore it. Create new USD file path in replace of the missing one, using the right mouse button menus.
* Please try out this USD sample file we created with Marvelous Designer and see how the new USD support can benefit your workflow. Step by step tutorial for how to export this USD file from Marvelous Designer coming soon.
