Tim van Dulmen has shared a collection of models inspired by Treasure Planet, which includes a free Morph rig for Maya and a movie-themed model pack.
The creator shared that the Morph rig was the first fully rigged character in Maya that he had created. It includes the rig itself, basic body textures, and full face and body rig. According to the artist, one of the challenges was to create the Eye/Brow rig. He used a combination of a Lattice deformer for the eyes and a joint setup for the brows. The author notes that the rig is not game-ready and is suitable for Maya 2022 and higher.
The pack contains the models of Jim Hawkins, Morph, and Alponian Solar Surfer Model, along with basic textures for all models, and an FBX file and .ma file for each. The rig and the model pack are free.
Take a look at the animation test of the Morph rig and the characters' models:
