These are the character models from versions 0.38.x and 0.33d, updated to work with the latest RoR version (2022.04).
Both characters are using the original animations. As a result, animations for some newer actions (such as sidestep) are missing.

The 0.38 character features support for multiplayer colors:


Installation:

• Extract the downloaded zip into any folder
• Go to RoR's install directory (by default: C:\Program Files\Rigs of Rods)
• Open the resources folder, copy meshes.zip, materials.zip, and textures.zip (0.38 character only) to the Desktop
• Open meshes.zip, drag and drop character.mesh and character.skeleton
• Open materials.zip, drag and drop character.material
• Open textures.zip, drag and drop character.dds and character-alpha.png (0.38 character only)
• Move meshes.zip, materials.zip, and textures.zip from the Desktop back into the resources folder, overwriting if prompted.

To revert back to the default character, follow the above steps but with the contents of the "original" folder instead.
