About this project
What does Custom Tiers add?
What is probably one of my peeves when it comes to developing modpacks is that, in many cases, you're limited to what mod authors provide for tiers of machinery, there are some addons for stuff like mekansim and create, but they aren't customizable beyond what they provide.
This mod changes that, no need to crack open a java IDE just to add custom tiers of machinery to your modpack, just a startup event in kubeJS or adjusting a config is all you need. Textures are even pregened to match the base mod's textures (in most cases)
Do note that recipes aren't pregenned when you make a tier, those need to be added yourself.
There's an example config that's included with the mod on adding it to the game, the kubeJS snippit is on the Wiki page.
Supported mods:
- Create: More machines: (deployer, basin, spout, mechanical press, mixer, and depot)
- Sophisticated storage: (all storage blocks)
- Mekanism: (cables and pipes, tanks, intuction matrix, energy cube, bins. Machines in dev)
- Create: Millstone, Item Drain, and Encased Fan
Planned mods:
- Iron Jetpacks
- Mystical Agriculture: (armor, weapons, apples, diamonds, and furnace. Use with Mystical Customization.)
Not planned:
- Iron Furnaces: (use Iron furnaces: reburn)
- various mod's machine frame's: (use KubeJS)
- Mekanism circuts: (use KubeJS)
- Generators Galore: built into mod according to page
