Mekalus is an Unofficial Fork of "Oculus", made to fix Mekanism MekaSuit rendering with shaders.
Oculus is an Unofficial Fork of "Iris", made to work with Forge Mod Loader.
I backported a fix from Iris 1.21.1 to Oculus 1.19.2 and made a Pull Request, which has already been merged. The problem is that the author of Oculus, Asek3, is burnt out from modding, so it won't be published for an indefinite amount of time. However, hundreds of thousands of players are continuing to suffer from this problem, so I published this fork as a temporary solution.
The original mod is licensed under LGPLv3:
Under the terms of the LGPLv3 license, I have the right to publish a modified version of the software, as long as I adhere to the terms of the license. Specifically, LGPLv3 allows for redistribution of modified versions of the code, provided that the modified source code is also made available under the same license. This ensures that all users have the freedom to use, modify, and share the software under the same conditions as the original. By publishing my fork, I am following these requirements, making my changes available to the community and contributing to the open-source ecosystem. Furthermore, given that the original author is unable to maintain the mod at the moment, this action aims to support the community and address the needs of many players affected by the bug.
