You are returning the default model. You should return a class that extends BipedModel.

I'm not sure but try to check ServerWorld#findNearestStructure.

This is basic Java.

Why are you trying to use the universal? Use the installer.

Depends on the type of mod...

If the author hasn't done it one-sided, it means it's required on the client as well, so it will crash if you modify it to be server only.

Learn Java and don't rely on tutorials.

Learn java before modding. Also... @Override public int getDamageReductionAmount(EquipmentSlotType slotIn) { return this.damageReductionAmountArray[slotIn.getSlotIndex()]; } will not work for an index of 4 or higher and HEAD.getSlotIndex() returns 4.

Why...? Post the debug.log.

Mahou Tsukai seems to be for 1.15.2. Also, where do you download mods from?

In your .minecraft\logs folder.

Post the installer log.

Post the debug.log. Also, which version of forge do you have?

In your .minecraft\logs folder.

I can't understand your problem but if you have problems installing forge try to run the installer manually or use jarfix.

Show the method after you return your armor model and the class of the model.

Light Overlay is for 1.16.1.

This is the latest.log (and is unavailable). You have to post the debug.log.

Download java.

Have you done this?

Probably twitch broke the minecraft installation. Try to repair the installation or delete the minecraft folder (This one: C:\Users\Paf i jas\Twitch\Minecraft).

Post the debug.log.

Post the debug.log.

Run java -version in your cmd and post the output.

Do you have java 64-bit?
