# Summary
This is a dataset to train anime-style text-to-image or any text and image multimodal models without copyright/licensing concerns.
All assets/materials utilized in this dataset are CC0 or properly licensed, and no pretrained models or any AI models are used to build this dataset. 

## Image, Metadata and Dataset License

## Assets used in this dataset
- VRM models
  - These models are made by VRoid Project and shared under CC0.

- HDRI images
  - [Poly Haven](https://polyhaven.com/) (CC0)
- Pose data
  - Our original poses + poses from [VRM Posing Desktop](https://hub.vroid.com/apps/C5RyO1UeTrOT_gL5l4gXTgA_Lh819zgLdZmxhC-4kmw) with explicit permission from its author ElvCatDev.
  - Please note: pose data from VRM Posing Desktop is not CC0.
- Renderer
  - All rendering was made by a customized version of [Mitsua VRM Shoot!](https://vrmshoot.pages.dev/) which is our VRM rendering app.
 
 **In this dataset, any data including VRM, pose and captions from Mitsua Contributors (voluntary opt-in data providers) are not included.** 

## How we built this dataset
This dataset was built to effectively train color concepts in anime-style images without copyright issue.
Therefore, we first broke down the CC0 VRM texture into parts so that we were able to color each part separately.
Next, we built a system that would automatically color the texture while changing the environment HDRI image, pose, expression, camera angle, and post-effects, all while automatically rendering.
All captions were made with rule-based method based on manually predefined names.
So there is no knowledge leakage of copyrighted works which is typical when you use pretrained captioner.
As a result, all rendering for this dataset took less than one day with using single RTX 4090 desktop.
