As this mod is derivative of textures from Immersive Engineering ("IE"), I cannot formally license it under e.g. CC-BY-NC-ND, because I do not have the right to sublicense the IE assets I remixed. Formality aside, I broadly would like to offer the freedoms of that license. You can broadly use and share this mod freely. However, in particular:

• You must credit me by name ("Nihiltres"), and you must not claim it to be your own work. I'd also appreciate links to places where I've personally shared it, but that's not required.
• You may not use it commercially. For example, you may not sell it or a modpack containing it, share it in conjunction with advertising, or offer rewards in return for donations on something containing it.

You also must follow the terms of Minecraft and of IE, and I reserve the right to disallow any particular use or reuse of the mod despite this informal blanket permission.

There is one exception to the restriction on derivative uses: If you're developing IE, or an add-on for IE, you may reuse assets from this mod in that project so long as a) I am credited by name in a visible way, b) your use of the assets is substantively original rather than duplicating content from this add-on, and c) your use follows the conditions of IE's license both with respect to IE's assets and my remixes thereof.
