I followed a tutorial and downloaded the dev and src jars and put the dev jars into folder /eclipse/mods/ and the src jars into /lib folder in eclipse. I can't make the needed mods (CodeChickenCore, ForgeMultipart) to work inside eclipse.

From my research I found that all I need to do is register the blocks using MicroMaterialRegistry#registerMaterial, but I'm not sure if that is true.ġ. I'm making a simple mod which adds blocks and I want to make them cuttable into microblocks using Forge Multipart.
