[SOLVED] Render partially transparent block

[Jay Avery]

I have a block with a model which is supposed to look like a water block (partially transparent) with a crop (opaque) inside it. But I can't get it to render how I want it to. When I use the

CUTOUT

BlockRenderLayer

, it looks as expected with the water element fully opaque, obviously:

 

 

When I use the

TRANSPARENT

layer, some weird things happen with the different faces of the opaque and transparent elements. The crop is glitched so it doesn't look like it's sticking out of the water the correct amount (which you can see in the opaque render above). The glitch varies depending on what angle you view the block from.

 

 

Here is the json file for the model in case that's useful:

 

{
    "textures": {
        "rice": "jjmod:blocks/plants/rice",
        "water": "jjmod:blocks/plants/water",
        "particle": "jjmod:blocks/plants/rice"
    },
    "elements": [
        {   "from": [ 4, 0, 0 ],
            "to": [ 4, 16, 16 ],
            "faces": {
                "west": { "uv": [ 0, 0, 16, 16 ], "texture": "#rice" },
                "east": { "uv": [ 0, 0, 16, 16 ], "texture": "#rice" }
            }
        },
        {   "from": [ 12, 0, 0 ],
            "to": [ 12, 16, 16 ],
            "faces": {
                "west": { "uv": [ 0, 0, 16, 16 ], "texture": "#rice" },
                "east": { "uv": [ 0, 0, 16, 16 ], "texture": "#rice" }
            }
        },
        {   "from": [ 0, 0, 4 ],
            "to": [ 16, 16, 4 ],
            "faces": {
                "north": { "uv": [ 0, 0, 16, 16 ], "texture": "#rice" },
                "south": { "uv": [ 0, 0, 16, 16 ], "texture": "#rice" }
            }
        },
        {   "from": [ 0, 0, 12 ],
            "to": [ 16, 16, 12 ],
            "faces": {
                "north": { "uv": [ 0, 0, 16, 16 ], "texture": "#rice" },
                "south": { "uv": [ 0, 0, 16, 16 ], "texture": "#rice" }
            }
        },
        {   "from": [ 0, 0, 0 ],
            "to": [ 16, 14, 16 ],
            "faces": {
                "down":  { "texture": "#water" },
                "up":    { "texture": "#water" },
                "north": { "texture": "#water" },
                "south": { "texture": "#water" },
                "west":  { "texture": "#water" },
                "east":  { "texture": "#water" }
            }
        }
    ]
}

 

 

Is there anything I can do to fix this, or is it just a limitation of Minecraft's rendering process?

 

Edit: Solved using a

forge:multi-layer

model as Choonster suggested.

 

 

In case it helps anyone else, my blockstates file:

 

 

{
    "forge_marker": 1,
    "defaults": {
        "model": "forge:multi-layer",
        "transform": "forge:default-block"
    },
    "variants": {
        "normal": [{
            "custom": {
                "base": "jjmod:test#base",
                "Mipped Cutout": "jjmod:test#base",
                "Translucent": "jjmod:test#trans"
            }
        }],
        "base": [{
            "model": "jjmod:testRice"
        }],
        "trans": [{
            "model": "jjmod:testTranslucent"
        }]
    }
}

 

 

And the two model files, the crop (rendered on the mipped cutout layer):

 

{
    "textures": {
        "rice": "jjmod:blocks/plants/rice",
        "particle": "jjmod:blocks/plants/rice"
    },
    "elements": [
        {   "from": [ 4, 0, 0 ],
            "to": [ 4, 16, 16 ],
            "faces": {
                "west": { "uv": [ 0, 0, 16, 16 ], "texture": "#rice" },
                "east": { "uv": [ 0, 0, 16, 16 ], "texture": "#rice" }
            }
        },
        {   "from": [ 12, 0, 0 ],
            "to": [ 12, 16, 16 ],
            "faces": {
                "west": { "uv": [ 0, 0, 16, 16 ], "texture": "#rice" },
                "east": { "uv": [ 0, 0, 16, 16 ], "texture": "#rice" }
            }
        },
        {   "from": [ 0, 0, 4 ],
            "to": [ 16, 16, 4 ],
            "faces": {
                "north": { "uv": [ 0, 0, 16, 16 ], "texture": "#rice" },
                "south": { "uv": [ 0, 0, 16, 16 ], "texture": "#rice" }
            }
        },
        {   "from": [ 0, 0, 12 ],
            "to": [ 16, 16, 12 ],
            "faces": {
                "north": { "uv": [ 0, 0, 16, 16 ], "texture": "#rice" },
                "south": { "uv": [ 0, 0, 16, 16 ], "texture": "#rice" }
            }
        }
    ]
}

 

 

The water (rendered on the translucent layer):

 

{
    "textures": {
        "water": "jjmod:blocks/plants/water",
        "particle": "jjmod:blocks/plants/water"
    },
    "elements": [
        {   "from": [ 0, 0, 0 ],
            "to": [ 16, 14, 16 ],
            "faces": {
                "down":  { "texture": "#water" },
                "up":    { "texture": "#water" },
                "north": { "texture": "#water" },
                "south": { "texture": "#water" },
                "west":  { "texture": "#water" },
                "east":  { "texture": "#water" }
            }
        }
    ]
}

You can use the

forge:multi-layer

model to combine other models that are rendered in different layers. I explain this in more detail here.

Ahh, thank you so much - that looks like exactly what I need.
