[1.12.2] Cannot load .OBJ file [SOLVED]

[mirk]

I'm having some trouble getting my .OBJ file into Minecraft. I've got the OBJLoader.INSTANCE.addDomain() going. It fails to open the file, because for some reason, it keeps trying to load a .JSON file. I'm stepping through the code and it fails in ModelLoader.getModelLocation(), I think.

How do I successfully load a .OBJ file?

 

For reference, here's my block state file.

Spoiler

 

{
	 "forge_marker": 1,
		 "defaults": 
		 {
			 "textures": 
			 {
				"all": "momcraft:blocks/models/magic_node.obj"
			 }
		 },
		 "variants": 
		 {
			"normal":
			{
				"model": "momcraft:blocks/models/magic_node.obj"
			},
			 "inventory": 
			{
				"model": "momcraft:blocks/models/magic_node.obj"
			}
	 }
}

I hope I got these BBS tags right.

 

Any help is massively appreciated!

change OBJ should be a png as this is a texture and not a model, and the model not obj should be json

Why is your texture an .obj file?

No.

When a model is looked up in the game the blocks/models/ path is added automatically. With your path the game tries to look for the model at momcraft:blocks/models/blocks/models/magic_node.obj which is incorrect. Just specify your path as momcraft:magic_node.obj similar to how I do here.

[mirk]

Okay, I've changed the texture path.

 

So to load an .OBJ file, I change it to a .JSON?

What should be in this new .JSON?

Alright, so I've done this, fixed an error that I got, and it's now throwing an exception when loading the model. Looks like I've got the right path, now, at least.

Do still need help if so post the exception.

[mirk]

Alrighty, so I've done some more investigation, and I think it's failing because it's trying to open magic_node.obj.json.

 

I'm not sure why this is happening.

We can't help without actual information. Post your blockstate and your log that has the exception.

[mirk]

Ah, of course. Sorry about that.

Your model path should not have ".obj at the end of it"

And your texture path should not have the ".png" at the end of it.

These will be automatically appended.

[mirk]

Okay, so I took those out, but it's still not very happy about these model files.

Did I perhaps do something wrong exporting them from Blender?

Is there a guide to doing this?

There is a forge docs page for models and it includes .obj files.

I've given that a read, but I was hoping for something a little more in-depth and Blender-related.

Do I triangulate the model?

My model has several meshes: does this affect the import process?

Do I use the "Objects as OBJ groups" option in Blender's .OBJ exporter?

 

Sorry for all of the questions, I'm mostly just venting my frustrations at this point.

I am unsure as to the process of exporting and making the model myself. But I believe that if it was finding your file it would be throwing a different exception our way, than the one that specifies a json file. Could you post the file path to your .obj and .mtl file and show the code where you call OBJLoader.addDomain also add the .obj extension back to your blockstate file according to the docs that is the correct way to do that.

Alright, so I've put the .obj back into the blockstates file.

 

This is in my MoMCraft.java file, my main mod file. I'm not sure if this is the right place to do it or not.

Spoiler

@EventHandler
public void init(FMLInitializationEvent event)
{
	OBJLoader.INSTANCE.addDomain(MODID);
}

 

And the path to my model and material is simply:

assets/momcraft/models/block/magic_node.obj
assets/momcraft/models/block/magic_node.mtl

It has some way to go yet, but that's my model, loaded into Minecraft.

No problem, glad I could help. Also it will look weird if you model protrudes outside of a 1 block space into another blocks, so you may wanna shrink it a little.

[Draco18s]

And change the block type to not be a full, opaque cube so it doesn't create holes in the world.

Yeah, I'm going to scale it down a bit, it's a bit extra at the moment. I think the missing texture is actually a problem in Blender, because I have no idea how to use it properly.

Yes, that too! I was following a tutorial that was teaching about opaque cubes and stuff, so I just left it in like a dingus.
