litematica VS malilib-forge

Litematica - Litematica is a client-side schematic mod for Minecraft, with also lots of extra functionality especially for creative mode (such as schematic pasting, area cloning, moving, filling, deletion).

Other options (if you can't/won't install Carpet mod) that may or may not be feasible are pasting the schematic in multiple phases, for example by first removing all observers from it (via the schematic edit mode, see the wiki on GitHub) and then again with replace behavior None and the observers restored. But if you have any observer chains, then this likely would still trigger stuff unless you handle each chain manually, removing the first and/or last observer (again using edit mode) before pasting.

Can you clarify what exactly you want to do? If you just want to change a block type in the schematic file, you can do it via the Edit Schematic mode in Litematica. See: https://github.com/maruohon/litematica/wiki/Schematic-Editing

See this: https://github.com/maruohon/litematica/issues/601

You can use the Schematic Edit mode to change, add or remove blocks in the schematic see the wiki here. But it's not possible to expand or shrink the size of the regions, so you are limited to the original size of the schematic.

You can use the Schematic Verifier to highlight one (or more) block types at a time. There isn't yet an option to filter the rendered block types, other than using the Schematic Edit mode to remove everything else. See: https://github.com/maruohon/litematica/wiki/Schematic-Editing

I found this fork of Litematic for Forge 1.16 (https://github.com/ZacSharp/litematica-forge-1.16) but I am having trouble building the jar file for it. The Malilib fork compiles just fine (https://github.com/ZacSharp/malilib-forge-1.16), but the Litematica one says there are deprecated features that are incompatible with Gradle 5.0, and I have no idea how to fix it.
