Armature setup

Rigging is the process that enables the clothing object to move and deform with a Roblox character's rigging armature. In this tutorial, you'll parent the t-shirt to Roblox's provided standard R15 rig and verify the Automatic Skinning Transfer data. After rigging, be sure to test out some basic poses to ensure that your clothes move and stretch correctly with any character body.

The next two rigging sections cover the following processes:

1. Downloading and appending a standard R15 armature to your project.
2. Parenting the rig with Blender's automatic weights.
3. Testing poses.

Transfer armature

Roblox provides base rigging armatures that you can import into your own project. While it is possible to create your own rigs, importing a premade rig with the proper configuration saves you time and reduces the potential for error.

To import a standard R15 rig into your file:

1. Download Roblox's Rig_and_Attachments_Template.blend, but do not open this project.

2. In your current clothing project, return to Object mode.

3. Navigate to File > Append, and select the saved Rig_And_Attachments_Template.blend file. An additional folder structure appears.

   

4. Select Armature > Armature and press Append. An armature object is added to your workspace.

   

5. Reorient the armature:

   1. With the armature active, open the Item tool sidebar.

   2. Adjust the rotation so the armature is correctly aligned with your mesh.

   3. After alignment, navigate to Object > Apply > All Transforms to freeze your new rotation values.

      

Parent armature

With the armature rig in place, you can use Blender's Parent with Automatic Weights functionality to quickly set your t-shirt mesh as a child of the armature. This feature also applies vertex weighting, or skinning, automatically to your mesh, which can save you significant time over skinning your clothing manually.

To parent the t-shirt to the rig:

1. Select LongSleeve, then hold Shift and click the Armature object. Ensure that the armature object is the last object selected.
2. Right-click in the viewport, then select Parent > With Automatic Weights from the contextual menu.
