I can't import EntityRendererFactory. I don't know why. I'm using Minecraft 1.20.1. I'm also using geckolib version 4.2 if that helps.

This is the import statement:

import net.minecraft.render.entity.EntityRendererFactory;

Help would be greatly appreciated, I can't find anything on this issue anywhere and it's driving me insane because it's the only problem in between me and spawning my modded entity.

The issue tracker is for final issue reports and feature requests, not general problems. For those, start a Discussion, or visit the Discord.

It's likely you're using split sources (both src/main and src/client exist), as that's a default now because it's recommended.
Client-only code such as entity renderers must be in src/client. src/main cannot access client-only code, to prevent accidental usage of client-only code on dedicated servers.

If you have further questions, as mentioned, start a discussion, or visit the Discord.

I resolved my issue, apologies for the issue posting, I just couldn't find any anything relating to my problem online.
