Hey, I have encountered another Problem whilst trying to render an custom OBJ Model as Item.
The console once again tells me no Errors, but my Item wont Show up in the Game.

Blockstate File (this should be right, as I got missing Location Errors until I added this): 

{
    "forge_marker": 1,
    "defaults":	{
        "textures":{},
        "model": "zeldadungeons:small_key.obj"
    },
    "display":{}
}

I wont include the obj model file as it is 6000 lines Long.

This is the .mtl file, referencing my texture: 

# Blender MTL File: 'None'
# Material Count: 1

newmtl Material.001
Ns 94.117647
Ka 1.000000 1.000000 1.000000
Kd 0.125947 0.125947 0.125947
Ks 0.022227 0.022227 0.022227
Ke 0.000000 0.000000 0.000000
Ni 1.000000
d 1.000000

Have you told Minecraft that you need an OBJ model?

OBjLoader::loadModel

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

No, I haven't. In fact, I do not even know where I should call it? Do I Need to do it in the class that Registers my models? 

package net.zeldadungeons.init;

import net.zeldadungeons.ZeldaDungeons;
import net.zeldadungeons.init.blocks.BlockPressureSwitch;
import net.zeldadungeons.util.MeshDefinitionFix;
import net.minecraft.block.Block;
import net.minecraft.block.state.IBlockState;
import net.minecraft.client.renderer.ItemMeshDefinition;
import net.minecraft.client.renderer.block.model.ModelBakery;
import net.minecraft.client.renderer.block.model.ModelResourceLocation;
import net.minecraft.init.Items;
import net.minecraft.item.Item;
import net.minecraft.util.ResourceLocation;
import net.minecraftforge.client.event.ModelRegistryEvent;
import net.minecraftforge.client.model.ModelLoader;
import net.minecraftforge.client.model.obj.OBJLoader;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;
import net.minecraftforge.fml.relauncher.Side;

@Mod.EventBusSubscriber(value = Side.CLIENT, modid = ZeldaDungeons.MODID)
public class Modelizer {
	public static final Modelizer INSTANCE = new Modelizer();

	@SubscribeEvent
	public static void registerAll(final ModelRegistryEvent e) {
		INSTANCE.registerItemModels();
		INSTANCE.registerBlockModels();
	}

	private void registerItemModels() {
		registerItemModel(Itemizer.FAIRY_SLINGSHOT);
		registerItemModel(Itemizer.SMALL_KEY);

	}

	private void registerBlockModels() {
		registerBlockItemModel(Blockizer.PRESSURE_SWITCH.getDefaultState());
	}

	private void registerItemModel(Item item) {
		final ModelResourceLocation resource = new ModelResourceLocation(item.getRegistryName(), "inventory");
		ModelLoader.setCustomModelResourceLocation(item, 0, resource);
	}

	private void registerBlockItemModel(final IBlockState state) {
		final Block block = state.getBlock();
		final Item item = Item.getItemFromBlock(block);

		if (item != Items.AIR) {
			registerItemModel(item);
		}
	}
}

I already added the Domain of my Mod to the ObjLoader.

I believe it is used instead of ModelLoader.setCustomModelResourceLocation.

I haven't messed with using OBJ models myself, try searching the forums for OBjLoader

That is used to manually load a model (Equivalent of ModelLoaderRegistry#getModel)

To have the ObjLoader scan your resources, one needs to call OBJLoader::addDomain(modid) during either the ModelRegistryEvent or preInit. The former is preferred.

I already called it, in the Log I posted it says "added zeldadungeons as a domain".

 

Maybe it is a problem with the model itself?

I'm not sure how you are not getting any issues. Minecraft needs the variants for this block, which by default are "normal" and in the case of corresponding itemblocks, "inventory".
 

This is how I usually write my blockstates for OBJ models. Though you'll likely won't need the "transform" block, and the "defaults": "model" should correspond to "forge:default-block"

It doesn't work yet. Do I have to pay attention to something while exporting an obj file? Like, how big is it or how to properly unwrap the model? I would post a screenshot but it is simply invisible in my inventory... That means that forge somehow loads it but not the right way, doesn't it?

Perhaps.

What program do you use to create the OBJ models?

I know that in Blender, with default settings, a normal sized block corresponds to a cube at x 0.5 y -0.5 z 0.5 at scale 0.5. While I know that you are not using a block, this should help you narrow down issues with size and/or translation

 

The ObjLoader also only support faces with a maximum of 4 vertices. Be sure to have the checkbox for "triangulate faces" marked, though issues with that should be logged.

 

This could also be an issue with the texture. Are you applying the texture to the material, or to an actual UV-map? The second option is the one I use.

Try setting the render to "textured" at the bottom of the screen, to get a (bad) preview of the model with texture.

 

Also be sure that the Normals for this item are OK. If the model is rendered inside-out, you wouldn't be able to see it.

      Issue trying to run my mod when I have Oculus as a dependancy

      By timy_g · Posted

      So, First of I am new to modding so bare with me I am creating a 1.20.1 forge mod that needs Oculus/Embeddium as a dependancy because later on I need to add custom shaders in for lights and such. I am using ParchmentMC as I've heard its better because of namings of things but that doesn't seem to like it when I run it alongside Oculus (Its a very barebones script adding two blocks and an item, and tested it before I did this) The 4 errors I get when I run 'runClient' is Caused by: org.spongepowered.asm.mixin.transformer.throwables.MixinTransformerError: An unexpected critical error was encountered Caused by: org.spongepowered.asm.mixin.throwables.MixinApplyError: Mixin [mixins.oculus.json:texture.MixinAbstractTexture] from phase [DEFAULT] in config [mixins.oculus.json] FAILED during APPLY Caused by: org.spongepowered.asm.mixin.injection.throwables.InvalidInjectionException: Critical injection failure: @Inject annotation on iris$afterGenerateId could not find any targets matching 'Lnet/minecraft/client/renderer/texture/AbstractTexture;m_117963_()I' in net.minecraft.client.renderer.texture.AbstractTexture.
