How to create custom 3D models with wavefront obj (in 1.10.2) ?

I have a problem with my mod. I don´t know how to create custom models from wavefront obj files. I watched some tutorials but it still isn´t working for me. I hqave the OBJLoader and I have the blockstate file (https://pastebin.com/eCLFEfmw), the mtl file (https://pastebin.com/f8QC47WD) and the obj file (https://pastebin.com/PaQ4AEdh ) but it won´t work. Every time I start the test client it gives me this error: https://pastebin.com/NtB3zgUT . Please give me a simple answer because I´m not good at creating custom models. I know things about java but there is still much for me to learn.

Caused by: java.io.FileNotFoundException: 110core:models/item/110core.hektometer.json

You haven't shown your code, but it looks like you're putting your domain (mod id) into the path part of your resource location (in addition to the domain part, where it actually belongs).

Yeah, I can see a few problems here offhand...

 

  • Stop using getItemModelMesher() and start using setCustomModelResourceLocation().  And do your model registration in an event handler for ModelRegistryEvent.
  • Don't use upper- or mixed-case resource locations. "blockHektometer" is bad, "block_hektometer" is good.
  • Using getUnlocalizedName() to determine the model resource location like you do in ModBlocks#registerRender() is horrible practice.  The block/item registry name should be considered the source of truth, not the translation key.  (So derive your translation keys and model resource locations from your registry names)
  • Start using RegistryEvent.Register<Block> /  RegistryEvent.Register<Item> for registering your blocks and items (and other resources like sounds...), and move away from doing that explicitly in an init() method.  See https://mcforge.readthedocs.io/en/latest/concepts/registries/

Um, this stuff:

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.

Ok, so, one, that tutorial is out of date

Two, that tutorial does some awful, awful things.

 

Show your main class.

How do you expect to display the item in the inventory?

By registering an item model.

And where do you think it goes to go find that model?

At the resource location you give it.

So what does it expect to find there?
A JSON file.

You need an item model that has a parent of the block model's json

    • They were already updated, and just to double check I even did a cleanup and fresh update from that same page. I'm quite sure drivers are not the problem here. 
    • i tried downloading the drivers but it says no AMD graphics hardware has been detected    
    • Update your AMD/ATI drivers - get the drivers from their website - do not update via system  
    • As the title says i keep on crashing on forge 1.20.1 even without any mods downloaded, i have the latest drivers (nvidia) and vanilla minecraft works perfectly fine for me logs: https://pastebin.com/5UR01yG9
    • Hello everyone, I'm making this post to seek help for my modded block, It's a special block called FrozenBlock supposed to take the place of an old block, then after a set amount of ticks, it's supposed to revert its Block State, Entity, data... to the old block like this :  The problem I have is that the system breaks when handling multi blocks (I tried some fix but none of them worked) :  The bug I have identified is that the function "setOldBlockFields" in the item's "setFrozenBlock" function gets called once for the 1st block of multiblock getting frozen (as it should), but gets called a second time BEFORE creating the first FrozenBlock with the data of the 1st block, hence giving the same data to the two FrozenBlock :   Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=head] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@73681674 BlockEntityData : id:"minecraft:bed",x:3,y:-60,z:-6} Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=3, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=2, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} here is the code inside my custom "freeze" item :    @Override     public @NotNull InteractionResult useOn(@NotNull UseOnContext pContext) {         if (!pContext.getLevel().isClientSide() && pContext.getHand() == InteractionHand.MAIN_HAND) {             BlockPos blockPos = pContext.getClickedPos();             BlockPos secondBlockPos = getMultiblockPos(blockPos, pContext.getLevel().getBlockState(blockPos));             if (secondBlockPos != null) {                 createFrozenBlock(pContext, secondBlockPos);             }             createFrozenBlock(pContext, blockPos);             return InteractionResult.SUCCESS;         }         return super.useOn(pContext);     }     public static void createFrozenBlock(UseOnContext pContext, BlockPos blockPos) {         BlockState oldState = pContext.getLevel().getBlockState(blockPos);         BlockEntity oldBlockEntity = oldState.hasBlockEntity() ? pContext.getLevel().getBlockEntity(blockPos) : null;         CompoundTag oldBlockEntityData = oldState.hasBlockEntity() ? oldBlockEntity.serializeNBT() : null;         if (oldBlockEntity != null) {             pContext.getLevel().removeBlockEntity(blockPos);         }         BlockState FrozenBlock = setFrozenBlock(oldState, oldBlockEntity, oldBlockEntityData);         pContext.getLevel().setBlockAndUpdate(blockPos, FrozenBlock);     }     public static BlockState setFrozenBlock(BlockState blockState, @Nullable BlockEntity blockEntity, @Nullable CompoundTag blockEntityData) {         BlockState FrozenBlock = BlockRegister.FROZEN_BLOCK.get().defaultBlockState();         ((FrozenBlock) FrozenBlock.getBlock()).setOldBlockFields(blockState, blockEntity, blockEntityData);         return FrozenBlock;     }
