Character Rig Options

Uthana has three characters, accessible via the Character tab on your account, that are compatible with Roblox Studio:

  • R15 Female Block Avatar
  • R15 Male Block Avatar
  • R15 Classic Avatar

These meshes are taken from default Roblox characters with the R15 rig. If animation is downloaded on any of these three characters, the animation can be applied to any of the default Roblox R15 characters.

If any of these characters are selected in the Uthana motion viewer, there are some additional download options to make the downloaded FBX animation compatible with Roblox Studio.

The Download Motion dialog with FBX selected, 30 keyframes per second, and the Roblox Studio and in-place options checked.
Select "Download FBX animation for Roblox Studio"

Download Options

1. Animations uploaded to Roblox must be FBX files. If you select "Download FBX animation for Roblox Studio" it willl automatically be downloaded as an FBX.

2. Roblox Studio defaults to 30 frames/second, so 30 Keyframes/sec is the best option if you use that default setting.

3. Option to download the animation in-place (no root motion aside from up-down motion). This may be preferable for Roblox users.
