This is a lightweigt implementation of dear imguis java libs, also containing a render callback for mods to subscribe to. can be used via
maven { url 'https://maven.uuid.gg/releases' } modApi("com.redpxnda.nucleus:nucleus-editor-fabric:${rootProject.minecraft_version}+${rootProject.nucleus_editor_version}") jarjaring it is fully allowed if desired, altough a fair warning, at this point in time there seem to be some conflict with other imgui shipping mods like veil. we are looking into resolving these without just shipping the same imgui version if possible, as wed prefer a stable solution. we recommend to use the proper maven for mod-devs, as it pulls dependencies properly
