[1.14.4][RESOLVED] OBJ Models: How to Get Started

[blinky000]

Ok, now its almost working , get the model, and the item.  The item looks fine,  the block is too dark.

What is your "Kd" property set to in the .mtl?

[blinky000]

newmtl Material1
Ka 1.000000 1.000000 1.000000
Kd 1.000000 1.000000 1.000000
d 1.000000
d 1.0
map_Kd minecraft:blocks/stone_bricks

 

 

2nd problem can't get it to use minecraft textures,  tried with / without doman , and with/without blocks

Hmmm... Those values work just fine for me... Don't know what could be the issue there...

Back in 1.13, Mojang dropped the plural off alot of the directories. So textures/blocks is now textures/block.

[blinky000]

so i did get the stone block,  when placed in game was totally messed up,  thinking it might have to with texture size, or maybe it doesn't parse my .obj files like it did it 1.12  (using kHed)

It's strange,  it  looks perfectly fine in inventory and all views int the players hands

@Yanny7 My textures not working... And I got this glitch(?) thing going on with my block.

[blinky000]

That's exactly my problem, i temporarily fixed the taking out the side or floor setting the  voxel shape  starts  .0001  and ends .999 (stupid fix i know)

another problem of mine is some textures work orthers don't  , and they are all the same size

Using perspective handling from previous post I just got working block & item rendering from custom OBJ model, there is code snipped if it helps:

    private static final TRSRTransformation THIRD_PERSON_BLOCK = Transforms.convert(0, 2.5f, 0, 75, 45, 0, 0.375f);
    private static final ImmutableMap<TransformType, TRSRTransformation> BLOCK_TRANSFORMS = ImmutableMap.<TransformType, TRSRTransformation>builder()
            .put(TransformType.GUI, Transforms.convert(0, 0, 0, 30, 225, 0, 0.625f))
            .put(TransformType.GROUND, Transforms.convert(0, 3, 0, 0, 0, 0, 0.25f))
            .put(TransformType.FIXED, Transforms.convert(0, 0, 0, 0, 0, 0, 0.5f))
            .put(TransformType.THIRD_PERSON_RIGHT_HAND, THIRD_PERSON_BLOCK)
            .put(TransformType.THIRD_PERSON_LEFT_HAND, Transforms.leftify(THIRD_PERSON_BLOCK))
            .put(TransformType.FIRST_PERSON_RIGHT_HAND, Transforms.convert(0, 0, 0, 0, 45, 0, 0.4f))
            .put(TransformType.FIRST_PERSON_LEFT_HAND, Transforms.convert(0, 0, 0, 0, 225, 0, 0.4f))
            .build();

    @SubscribeEvent
    public static void onModelBakeEvent(ModelBakeEvent event) {
        try {
            IUnbakedModel model = ModelLoaderRegistry.getModelOrLogError(new ResourceLocation("toomanyores:block/water_wheel.obj"),
                    "Missing water wheel model");

            if (model instanceof OBJModel) {
                IBakedModel bakedModel = model.bake(event.getModelLoader(), ModelLoader.defaultTextureGetter(),
                        new BasicState(model.getDefaultState(), true), DefaultVertexFormats.BLOCK);

                IBakedModel bakedInvModel = model.bake(event.getModelLoader(), ModelLoader.defaultTextureGetter(),
                        new BasicState(model.getDefaultState(), true), DefaultVertexFormats.ITEM);
                bakedInvModel = new PerspectiveMapWrapper(bakedInvModel, BLOCK_TRANSFORMS);


                event.getModelRegistry().put(new ModelResourceLocation("toomanyores:waterwheel", ""), bakedModel);
                event.getModelRegistry().put(new ModelResourceLocation("toomanyores:waterwheel", "inventory"), bakedInvModel);
            }

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

I changed :

                        IBakedModel bakedModel = model.bake(event.getModelLoader(), ModelLoader.defaultTextureGetter(),
                                new BasicState(model.getDefaultState(), true), DefaultVertexFormats.POSITION_TEX_COLOR_NORMAL);

 

from DefaultVertexFormats.BLOCK

 

 

 

I still had to use :

		    @SubscribeEvent
		    public static void onPreTextureStitch(TextureStitchEvent.Pre event) { 
		        event.addSprite(
		          ResourceLocation.tryCreate("yabmm:block/rose_quartz_panel"));
		    }

 

BUT, only if the texture had not been previously used on a resisted block.

 

I assume its a timing thing

 

 

[Yanny7]

You have to register it in TextureStitchEvent.Pre if this texture was not used by another block/whatever. Only used textures are registered, not all in your textures folder.

try this in your block:

@Override
public boolean isVariableOpacity() {
    return true;
}

[jun2040]

@Yanny7 I am using TextureStitchEvent.Pre but it's not working. The lighting works now tho. Thanks.

[blinky000]

Did you try changing the DefaultVertexFormats.  on the block

This should fix that problem, the method is marked as deprecated yet the game uses it. *sigh* Mojang...

@Override
public boolean isSolid(BlockState p_200124_1_)
{
  return false;
}

I cannot understand what you mean.

[blinky000]

 IBakedModel bakedModel = model.bake(event.getModelLoader(), ModelLoader.defaultTextureGetter(),
                        new BasicState(model.getDefaultState(), true), DefaultVertexFormats.BLOCK);

 

 

I used DefaultVertexFormats.POSITION_TEX_COLOR_NORMAL  on the block bake instead of BLOCK

I did that and it doesn't work. It seems like the objLoader is not trying to find .obj. Its searching for the json file.

Blockstate:

 

{
  "forge_marker": 1,
  "defaults": {
  },
  "variants": {
    "": [{"model": "yabmm:block/test_block"}]
  }

 

test_block.json:

{
  "model": "yabmm:test_block.obj"

 

so you have a <model..json  AND a <model>.obj

Does anyone know how to bake multiple models?

Assuming nothing has changed between 1.14 version, take a look at this: #onModelBakeEvent.

Is copy-pasting the entire code the only way to bake multiple models?

This is the code:

try {
            IUnbakedModel model = ModelLoaderRegistry.getModelOrLogError(new ResourceLocation("toomanyores:block/water_wheel.obj"),
                    "Missing water wheel model");

            if (model instanceof OBJModel) {
                IBakedModel bakedModel = model.bake(event.getModelLoader(), ModelLoader.defaultTextureGetter(),
                        new BasicState(model.getDefaultState(), true), DefaultVertexFormats.BLOCK);

                IBakedModel bakedInvModel = model.bake(event.getModelLoader(), ModelLoader.defaultTextureGetter(),
                        new BasicState(model.getDefaultState(), true), DefaultVertexFormats.ITEM);
                bakedInvModel = new PerspectiveMapWrapper(bakedInvModel, BLOCK_TRANSFORMS);


                event.getModelRegistry().put(new ModelResourceLocation("toomanyores:waterwheel", ""), bakedModel);
                event.getModelRegistry().put(new ModelResourceLocation("toomanyores:waterwheel", "inventory"), bakedInvModel);
            }

Do I have to copy this code and paste it to bake new models?
