Attributions and Third-Party Licenses
Rigipo is built on the work of other people. This page names that work, the licenses it comes under, and what we did or did not change. We want to be precise about this rather than vague.
Last updated: 8 August 2026
Rigipo Text to Animation
Rigipo Text to Animation is built on Kimodo, an open-source text-to-motion research project from NVIDIA. Project page: research.nvidia.com/labs/sil/projects/kimodo.
Rigipo does not claim authorship of the underlying motion generation model. The research, the training and the model architecture are NVIDIA's. What Rigipo adds is the product around it: the interface, the pipeline, the export formats and the engine integrations.
Kimodo source code
- Licensed under the Apache License, Version 2.0.
- Copyright (c) NVIDIA CORPORATION & AFFILIATES. All rights reserved.
- Rigipo has modified this code. Our changes are our own and are not endorsed by or attributable to NVIDIA.
- A copy of the Apache License 2.0 and the relevant NOTICE content is included with the product.
Model weights
The model weights are licensed separately from the source code. Using the code under Apache 2.0 does not grant any rights to the weights. Do not confuse the two licenses.
- The models Rigipo uses by default are from the Kimodo-SOMA-RP / Kimodo-G1-RP family, distributed by NVIDIA under the NVIDIA Open Model License.
- Rigipo uses these models under the terms of that license.
- NVIDIA does not endorse Rigipo. Our use of these models does not imply any partnership, sponsorship, review or approval by NVIDIA.
What we do not use
- The SMPL-X-based Kimodo variant is distributed under the NVIDIA Internal Scientific Research and Development (R&D) Model License. That license does not permit commercial use, and this variant is not used in the Rigipo commercial product.
Meta Llama 3
Built with Meta Llama 3
Rigipo Text to Animation includes Meta Llama 3. The product downloads the Meta-Llama-3-8B-Instruct model and uses it as the text encoder. The text encoder reads your prompt and turns it into the input for the motion model.
- Copyright (c) Meta Platforms, Inc. All rights reserved.
- Use of this model is governed by the Meta Llama 3 Community License Agreement.
- The Meta Llama 3 Acceptable Use Policy also applies. Rigipo follows both documents.
- The full license text and the required attribution ship with the product.
