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

[FriedrichLP]

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.

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).

Well this is my code:

the block class: https://pastebin.com/6t66QMgm

the class where I register my block: https://pastebin.com/3wf499Wx

and the client proxy class: https://pastebin.com/MDTN3f7t

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/.

What exactly do I need to change?

Um, this stuff:

25 minutes ago, desht said:

• getItemModelMesher() -> setCustomModelResourceLocation().
• -> And do your model registration in an event handler for ModelRegistryEvent.
• "blockHektometer" -> "block_hektometer"
• getUnlocalizedName() -> registry name
• -> Start using RegistryEvent.Register<Block> /  RegistryEvent.Register<Item>  See https://mcforge.readthedocs.io/en/latest/concepts/registries/.

Well I did everything he said but it won´t work. What am I doing wrong???? Alo I did everything this turorial said but it didn´t work: https://wiki.mcjty.eu/modding/index.php/Render_Block_OBJ-1.9 (I know that it is for 1.9 but I thought it should work for 1.10 too)

Ok, so, one, that tutorial is out of date

Two, that tutorial does some awful, awful things.

 

Show your main class.

OK here is it: https://pastebin.com/VjhxbReJ

Despite the versioning on McJty's tutorials, his 1.12 series is much better, and still applies as long as you're on a recent 1.10.2 version of Forge (which you should be).

ok I´ll try out the 1.12 version of his tutorial and make my classes look a bit nicer

[FriedrichLP]

ok...... I made everything exactly like the tutorial but I still get the same error. And what does this mean: "Caused by: java.io.FileNotFoundException: 110core:models/item/block_hektometer.json" ?

[Draco18s]

FileNotFoundExceptions mean that the file....was not found

[FriedrichLP]

I know but why does it search for this file? I‘ve never said that it should do that. I mean I never programmed it.

[Draco18s]

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.

[FriedrichLP]

So I should copy the block models and json and do the same for the item?

[Draco18s]

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