[1.15.1] How to import OBJ files as block models

[MaxHyper]

I know 1.15 is still quite new, but has anybody figured out how to use .obj files as models? Since 1.15 changed the whole rendering system solutions for 1.14 do not work.
The main issue is that OBJLoader.INSTANCE.addDomain() no longer exists.
Thanks in advance.

You don't need to do that call anymore, it just works™️ if you reference the model from your blockstate json

Okay ive been trying for a while and havent been able to figure it out. When i reference the obj file from the blockstate i get an error where its adding ".json" to the end on its own. 

[00:19:43] [Server-Worker-6/WARN] [minecraft/ModelBakery]: Unable to load model: 'brassnsteam:block/obj/pipe_core_valve.obj' referenced from: brassnsteam:iron_pipe#center=true,down=true,east=true,north=true,south=true,up=true,waterlogged=true,west=true: java.io.FileNotFoundException: brassnsteam:models/block/obj/pipe_core_valve.obj.json

Is there nothing i need to do in the code? Messing with the blockstate only seems to not be enough.

You saved my life! I've been asking for days and still can't find an answer, you're luckier than me. I hope you find a solution and that I can try it, otherwise it's hopeless. P.S.: If you can help me, I would be very happy. The Link: is this.

I would like to help you, but unfortunately I do not know the answer to your problem.

Post your logs + BlockState json & model

The only log I have that is meaningful is the line on my previous comment. 

 

Here's the blockstate, the obj part is only the second bit.

Not sure what you mean by posting the model since its an obj, but heres its location: (rightmost file)

I think that all you need to do is remove the ".obj" from

"apply": { "model": "brassnsteam:block/pipes/attachments/pipe_core_valve.obj" }

and it should work.

Nope, its still looking for a .json
Id like to point out that the other file named pipe_core_valve.json in the picture i sent was just a test and is unrelated.

[OnlyJoe]

Using .obj files seems to have changed a lot, I am assuming that 1.15 has removed the ForgeLoader for blockstates, as the multipart system really covers everything it did (except for loading .obj).

 

The new way to load models:

Your blockstate should use the vanilla method (without".obj" on the model name) e.g.:

{
  "variants": {
    "": {
      "model": "MODID:block/MODEL"
    }
  }
}

 

Every model, in the "models/block" path, now needs, MODEL.json, MODEL.obj, MODEL.mtl.

In your new MODEL.json file you need to tell it to use the OBJLoader from forge, and give the full resource path to your ".obj" file, eg:

{
  "loader": "forge:obj",
  "model": "MODID:models/block/MODEL.obj",
  "flip-v": true
}

 

 

The options you can include in the new MODEL.json file are:

{
	"loader": "forge:obj",  //to inform the resource loader to use OBJLoader
	"model": <<resource path to .obj file>>,
	"detectCullableFaces": true|false,
	"diffuseLighting": true|false,
	"flip-v": true|false,
	"ambientToFullbright": true|false,
	"materialLibraryOverride": <<resource path to material library if you need different materials on the same .obj>>,
}

 

Remember to update the paths for your textures in the .mlt file to use resource paths (without ".png").

 

[blinky000]

I'm not sure how to path the texture in the .mtl file

 

Can you give me working example  (blockstate,  model.json,   model.obj  ,model.mtl) files.

I have got everything setup up, but no mater what the model is i get this: 

 

 

the .obj file was a cube.  No matter what model i use i get that

the blue color is from the texture

That's work for me, just imported on the json files, just the uv's are messed up, i'm registered the block normally without any function to import models or textures
on Forge 1.15.2 and mapping 20200408-1.15.1

model.json

{
  "parent": "forge:item/default",
  "loader": "forge:composite",
  "parts": {
    "part1": {
      "loader": "forge:obj",
      "model": "MOD_ID:models/block/mesh/model.obj"
      "textures": {
        "#YourMaterialName": "MOD_ID:blocks/modeltexture"
      }
    }
  }
}

 

blockstate.json

{
  "variants": {
    "": {"model":  "MOD_ID:block/model"}
  }
}

 

item.json
 

{
  "parent": "MOD_ID:block/model"
}

 

model.mtl

Sorry can you please said how work OBJLoader.INSTANCE.addDomain() in more downgrades versions of minecraft how for example 1.12?
