i'm on 1.13.2 and use Rift, did download MaLiLib, only litematica and MaLiLib. but when start it instantly crash, i check the crash report and go no new file, i tried again this time with out the mods to see if it the API, but it ran normally, so i think it must be the mods, again i use Rift 1.13.2 and did download the required mod for litematica.

what does the crash say on the launcher?

I assume you are using Litematica version litematica-rift-1.13.2-0.0.0-dev.20190611.200317.jar, which is the latest on CurseForge? Then you must use malilib version malilib-rift-1.13.2-0.10.0-dev.19.jar, otherwise you will get a crash due to mismatching code between the mods.

Also if check if there is an file in %appdata%\.minecraft\libraries\com\github\Chocohead\Rift\jitpack-SNAPSHOT, otherwise check for the fix in the faq of litematica

@satoru101 did you get it working?

yes it work thank so much
