So i've tried looking at the ModelFluidDebug class here

https://github.com/MinecraftForge/MinecraftForge/blob/b45fd787f36626ef84f26e881848167fec5957b5/src/test/java/net/minecraftforge/debug/ModelFluidDebug.java

 

but is not working

I have done a new workspace with only that file (so basically a mod that adds only that fluid) but the texture is missing.

This is the main mod file (and also the only class in the mod)

package com.example.examplemod;

import net.minecraft.block.material.Material;
import net.minecraft.block.state.IBlockState;
import net.minecraft.client.renderer.ItemMeshDefinition;

import net.minecraft.client.resources.model.ModelResourceLocation;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.util.ResourceLocation;
import net.minecraftforge.client.model.ModelLoader;

@Mod(modid = ModelFluidDebug.MODID, version = ModelFluidDebug.VERSION)
public class ModelFluidDebug
{
    public static final String MODID = "ForgeDebugModelFluid";
    public static final String VERSION = "1.0";

    private static ModelResourceLocation fluidLocation = new ModelResourceLocation(MODID.toLowerCase() + ":" + TestFluidBlock.name, "fluid");
    private static ModelResourceLocation gasLocation = new ModelResourceLocation(MODID.toLowerCase() + ":" + TestFluidBlock.name, "gas");

    @EventHandler
    public void preInit(FMLPreInitializationEvent event) { FluidRegistry.registerFluid(TestFluid.instance);
    FluidRegistry.registerFluid(TestGas.instance);
    GameRegistry.registerBlock(TestFluidBlock.instance, TestFluidBlock.name);
    GameRegistry.registerBlock(TestGasBlock.instance, TestGasBlock.name); 
    Item fluid = Item.getItemFromBlock(TestFluidBlock.instance);
    Item gas = Item.getItemFromBlock(TestGasBlock.instance);
    ModelBakery.addVariantName(fluid);
    ModelBakery.addVariantName(gas);
    ModelLoader.setCustomMeshDefinition(fluid, new ItemMeshDefinition()
    {
        public ModelResourceLocation getModelLocation(ItemStack stack)
        {
            return fluidLocation;
        }
    });
    ModelLoader.setCustomMeshDefinition(gas, new ItemMeshDefinition()
    {
        public ModelResourceLocation getModelLocation(ItemStack stack)
        {
            return gasLocation;
        }
    });
    ModelLoader.setCustomStateMapper(TestFluidBlock.instance, new StateMapperBase()
    {
        protected ModelResourceLocation getModelResourceLocation(IBlockState state)
        {
            return fluidLocation;
        }
    });
    ModelLoader.setCustomStateMapper(TestGasBlock.instance, new StateMapperBase()
    {
        protected ModelResourceLocation getModelResourceLocation(IBlockState state)
        {
            return gasLocation;
        }
    });}

    public static final class TestFluid extends Fluid
    {
        public static final String name = "testfluid";
        public static final TestFluid instance = new TestFluid();

        private TestFluid()
        {
            super(name);
        }

        @Override
        public int getColor()
        {
            return 0xFF00FF00;
        }
    }

    public static final class TestGas extends Fluid
    {
        public static final String name = "testgas";
        public static final TestGas instance = new TestGas();

        private TestGas()
        {
            super(name);
            density = -1000;
            isGaseous = true;
        }

        @Override
        public int getColor()
        {
            return 0xFFFF0000;
        }
    }

    public static final class TestFluidBlock extends BlockFluidClassic
    {
        public static final TestFluidBlock instance = new TestFluidBlock();
        public static final String name = "TestFluidBlock";

        private TestFluidBlock()
        {
            super(TestFluid.instance, Material.water);
            setCreativeTab(CreativeTabs.tabBlock);
            setUnlocalizedName(MODID + ":" + name);
        }
    }

    public static final class TestGasBlock extends BlockFluidClassic
    {
        public static final TestGasBlock instance = new TestGasBlock();
        public static final String name = "TestGasBlock";

        private TestGasBlock()
        {
            super(TestGas.instance, Material.lava);
            setCreativeTab(CreativeTabs.tabBlock);
            setUnlocalizedName(MODID + ":" + name);
        }
    }
}

 

and that's the json file

{
    "forge_marker": 1,
    "variants": {
        "fluid": {
            "model": "forge:fluid",
            "custom": { "fluid": "testfluid" }
        },
        "gas": {
            "model": "forge:fluid",
            "custom": { "fluid": "testgas" }
        }
    }
}

 

any idea on why is not working?

Anybody? I don't understand why the fluid when placed down is invisible

UPDATE: i've added this to the TestFluidBlock class

@Override
        public int getRenderType()
        {
        	return 3;
        }

and now it gives me this

 

 

So apparently is not spreading like the normal water does, it fills all the space with "blocks", is because it has no texture? How can i give it one?

Still any idea?

I have got the same Problem too. Maybe this github code is wrong.

bump

Dunno if this helps, but MODID must be lowercase..

Which version of Forge are you using? The fluid model was added in 1.8-11.14.3.1464.

 

The FML log should tell you what's going wrong. If you don't know what to make of it, upload it to Gist and link it here.

 

Fluid textures are set from the

Fluid(String, ResourceLocation, ResourceLocation)

constructor (added at the same time as the fluid model). Your code is using the

Fluid(String)

constructor.

 

The fluid code on Forge's GitHub repository works for me in 1.8-11.14.4.1571.

I do this in the ModelResourceLocation

MODID.toLowerCase()

so it's always lower case when passed as argument to ModelResourceLocation ctor

Mmm... i'm using the 1.8-11.14.1.1375 version, i'll try it in that version

I do this in the ModelResourceLocation

MODID.toLowerCase()

so it's always lower case when passed as argument to ModelResourceLocation ctor

Well, that works.. But I'd really recommend making the MODID lowercase, as it will save you the time and tears when you forget to put it to lowercase. Give me one good reason for having an uppercase. 

ahahahah that was just a copy/paste from the github file, in fact in the mod where this will go it's lower case

wow... 

Anyway, what's your current problem?

Actually i had to test it in a newer version of Forge and see if it works As soon as i can i'll let you kow

Okay It will probably fix the issue

Ok, so updating the Forge version to the latest or the MC1.8 fixed the error

For anyone who want an example, this is the actual code

and this is the Json file

{
    "forge_marker": 1,
    "variants": {
        "fluid": {
            "model": "forge:fluid",
            "custom": { "fluid": "myfluid" }
        },
        "gas": {
            "model": "forge:fluid",
            "custom": { "fluid": "testgas" }
        }
    }
}

 

Note that the name specified in "custom" in the json file is the same name as specified in the class, otherwise it will have the default water texture Thanks Choonster for the tip
