NullPointerException when rendering a schematic placement

Minecraft version
1.20.1 Fabric
Mod version and malilib version
Litematica 0.15.4, Malilib 0.16.3
- Include the full mod file name
  the mod file name is just the version of mc and version of the mod (stable build)
  litematica-fabric-1.20.1-0.15.4.jar

If it helps to know, I also have Syncmatica, Litemoretica, Litematica E.C. Materials, Litematica Printer, Litematica Printer Easyplace Extension, Loosen Litematica, and Litematica Server Paster. (all at the latest versions as of 10.6.2024 12:30 gmt-6).
I am fairly sure it is not one of these as disabling them all doesn't stop the crash.
I also use Iris, but it is not that either as turning off shaders/completely disabling iris doesn't fix the crash.

A clear description of the issue
Litematica crashes when rendering a schematic placement because of a null variable not being updated. I am a developer myself but have no clue why it doesn't update this variable. in litematica/src/main/java/fi/dy/masa/litematica/render/schematic
/WorldRendererSchematic.java

java.lang.NullPointerException: Cannot invoke "fi.dy.masa.litematica.render.schematic.ChunkRenderDispatcherSchematic.scheduleChunkRender(int, int)" because "this.chunkRendererDispatcher" is null

The only way to really know is to try without them, for example first without all of them and if it doesn't crash then you can narrow down which mod exactly.

alright I'm going to go do this now

maruohon · Answer 5 · 2024-10-06T20:15:26.000Z

This is probably another case of some mod throwing an exception when loading into the world, which prevents some of Litematica's code from running that would come after that mod.

You can try adding -Dmixin.debug.verbose=true to the JVM arguments, and then in the console/log (after trying to load to a world) look for any mods that apply mixins to WorldRenderer aka. class_761. The offending mod is likely one of the other mods except Litematica that applies some mixins there.
