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.

I hope I got these BBS tags right.

 

Any help is massively appreciated!

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.

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.

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.

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.

And the path to my model and material is simply: 

assets/momcraft/models/block/magic_node.obj

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

Thank you so much for your help, Animefan8888.

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.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

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.

      Both Ars Nouveau and Chaos Awakens require a range of geckolib versions, and the build you sent is outside the range. Ars Nouveau has an update, but Chaos Awakens doesn't, which means I can't use the build you sent. Is there any other way to fix the crash?
