Hello,

 

While everything is perfectly fine in game, I have many errors displayed at launch.

Those errors are 

[Client thread/ERROR] [FML]: MultiModel minecraft:builtin/missing is empty (no base model or parts were provided/resolved)

Here's the part of the log with all of them : http://hastebin.com/oropesitil.md

 

I see no information about what could be causing this. I have googled the error to no avail.

If anyone knows when this kind of error spawns, that would be helpful.

From what I am reading, i looks like an issue in a Json file, like it is trying to call a parent file, I am guessing, called builtin/missing in the Minecraft assets folder. Try looking through your Json files and seeing if any parents are weird.

(It's one month old, I hope not enough to be a necro)

 

There's absolutely zero mention of builtin/missing in the project. This just cannot be the cause.

By adding/removing files I have narrowed it down to blockstates.

I'm looking for another kind of error in the JSON. Will update if anything new.

EDIT : Narrowed it down to one JSON blockstate file that is the cause of all error lines (dozens !)

The author of the JSON (nop, not me, that's a project) apparently wanted an empty model for a light source and wrote a wrong JSON : http://hastebin.com/zifagicobi.json
