OpenYSM is a Minecraft mod that replaces the standard player character model with a customizable one. The README, written in Chinese, presents the project as an open-source alternative to Yes Steve Model, a mod commonly known as YSM that does a similar job. This version is built against YSM 2.6.5 Forge and is offered so that players have a fully open implementation they can modify and redistribute on their own terms. Under the hood the mod uses a library called GeckoLib to handle the animation system, and it loads model and animation files in the format used by Minecraft Bedrock Edition. The README explains that this format choice is what lets players bring in their own character models and animations rather than being stuck with the default look. There is also an optional companion library written in C++ for faster rendering, kept in a separate repository called SIMD-Acceleration under the same OpenYSMDev organization. To build the mod from source, the README has you clone the repository, change into the folder, and run the Gradle build wrapper. The resulting jar file lands in build/libs. Contributions are welcomed in the form of issues, documentation improvements, bug fixes, and new features. The source code itself is released under the MIT license, while the bundled character models follow their own terms: the default model is released into the public domain through CC0, and a model called Wine Fox uses CC BY-NC-SA 4.0, which limits it to non-commercial use, requires attribution, and asks that any derived work uses the same license.
