[1.12.2] Cannot load .OBJ file [SOLVED]

Posted July 17, 20187 yr

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.

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.

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.

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?

Here's the console log:

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

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.

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

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.

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.

New Forum Design/Update: Issues and Suggestions

Unfortunately, it seems that Invision has decided that everything is locked down and no longer customizable.
Their attitude to anyone who wants to edit anything is 'Just accept it we know best and screw you for even insinuating that you want to customize your own site'
So there isn't much we can do about the layout of actual features.
Best bet for the editor is that psudo markdown works, so typing ` around words make code blocks.
Only options is to start writing bespoke modifications to the forum's php code itself, which I really don't want to do.
I would of stayed on v4 but the version of PHP that it supports is going EOL and Invision has stated they have no intentions of upgrading it.
They also removed the central community for finding plugins/community addons.
Overall it is my feeling that they are intentionally trying to kill off self-hosting communities by removing features and locking things down, in an effort to force everyone into using their paid hosting services.

My HOPE is that someone in the overall forum community will write an exporter for Invision to something like SMF. Which is what we were originally on before old team members decided enterprise software is better.

I don't know that either - newer worked with Invision Community 😕

The Forum/Guides show a customized toolbar:
https://invisioncommunity.com/4guides/themes-and-customizations/editor-and-emoticons_327/customizing-editor-toolbars-r132/
But I have no idea if this applies to v5

Regarding the Forum, "Mark all as read" seems to be hidden as default but is available if I click on my profile:
https://invisioncommunity.com/forums/topic/481218-fix-for-unreadmark-read/

I saw that it works here and also fixes the one unread thread mentioned in my first post - so I had just overlooked it

The toolbar changes are just QoL - if there is no way to change it at the moment, that's fine
