MC-161948Models with alpha channel do not render all faces consistently
The bug
When viewed through certain faces, other faces of a model with alpha channel transparency do not render.
How to reproduce
The easiest way to view this bug is to summon an invisible armor_stand with a semi-transparent block in its head armor slot:
/summon minecraft:armor_stand ~ ~ ~ {ArmorItems:[{},{},{},{id:"minecraft:black_stained_glass",Count:1}],Marker:1,Invisible:1,NoGravity:1}
In this way, every face can be observed independently of the others.
Affected models
Any model with alpha channel transparency is affected in a similar way. This currently includes:
- any stained_glass
- any stained_glass_pane
- minecraft:ice
- minecraft:slime_block
- minecraft:slime (entity)
Models without alpha transparency (i.e.: only full transparency) are not affected:
- minecraft:glass
- minecraft:glass_pane
- minecraft:beacon
- minecraft:iron_bars
Model rendering issues
The following table shows the deficiencies in model rendering for semi-transparent textures. This table is relative to the stained glass Model Cardinality (see below).
| Looking In Face | Renders Bottom | Renders Top | Renders North | Renders South | Renders West | Renders East |
|---|---|---|---|---|---|---|
| Bottom | N/A | No | No | No | No | No |
| Top | Yes | N/A | No | No | No | No |
| North | Yes | Yes | N/A | No | No | No |
| South | Yes | Yes | Yes | N/A | No | No |
| West | Yes | Yes | Yes | Yes | N/A | No |
| East | Yes | Yes | Yes | Yes | Yes | N/A |
This table does not appear to be the same for the stained glass pane model, though similar issues can be observed.
This table is the same for the slime entity model, but the faces are in a different orientation (see below).
Cause
There are multiple locations in the code and model files where the faces are added/defined in the order DOWN, UP, NORTH, SOUTH, WEST, EAST, and this can be seen in the table.
Visual evidence
Relative to the texture (when placed in the world) these are the assigned cardinalities of the faces for full blocks (stained_glass, ice, slime_block):
When looking through the face in the Looking Through column, the other faces in the Render X column contain the render status of those faces.
The slime model exhibits the same table, but in a different orientation, which can be seen here:
Here is an example model showing the extent of the issues:
In the model cardinality, this is looking from South-East-Above.
Note: this is not a block in the world, it is a Head Item on an invisible armor_stand.

Description
When viewed through certain faces, other faces of an item model with alpha channel transparency do not render.
Steps to Reproduce
The easiest way to view this bug is to summon an invisible armor_stand with a semi-transparent block in its head armor slot:

Affected Models
Any model with alpha channel transparency is affected in the exact same way. This currently includes:

Possible Cause?

Steps to Reproduce
The easiest way to view this bug is to summon an invisible armor_stand with a semi-transparent block in its head armor slot:
/summon minecraft:armor_stand ~ ~ ~ {ArmorItems:[{},{},{},{id:"minecraft:black_stained_glass",Count:1}],Marker:1,Invisible:1,NoGravity:1}In this way, every face can be observed independently of the others.
Affected Models
Any model with alpha channel transparency is affected in a similar way.
This currently includes:
- any stained_glass
- any stained_glass_pane
- minecraft:ice
- minecraft:slime_block
- minecraft:slime (entity)
Models without alpha transparency (i.e.: only full transparency) are not affected:
- minecraft:glass
- minecraft:glass_pane
- minecraft:beacon
- minecraft:iron_bars
Model Rendering Issues
The following table shows the deficiencies in model rendering for semi-transparent textures. This table is relative to the stained glass Model Cardinality (see below).
Looking In Face Renders Bottom Renders Top Renders North Renders South Renders West Renders East Bottom N/A No No No No No Top Yes N/A No No No No North Yes Yes N/A No No No South Yes Yes Yes N/A No No West Yes Yes Yes Yes N/A No East Yes Yes Yes Yes Yes N/A This table does not appear to be the same for the stained glass pane model, though similar issues can be observed.
This table is the same for the slime entity model, but the faces are in a different orientation (see below).
Cause
There are multiple locations in the code and model files where the faces are added/defined in the order DOWN, UP, NORTH, SOUTH, WEST, EAST, and this can be seen in the table.
Visual Evidence
Relative to the texture (when placed in the world) these are the assigned cardinalities of the faces for full blocks (stained_glass, ice, slime_block):
When looking through the face in the Looking Through column, the other faces in the Render X column contain the render status of those faces.
The slime model exhibits the same table, but in a different orientation, which can be seen here:
Here is an example model showing the extent of the issues:
In the model cardinality, this is looking from South-East-Above.
Note: this is not a block in the world, it is a Head Item on an invisible armor_stand.
Here is an interactive example:
The bug
When viewed through certain faces, other faces of a model with alpha channel transparency do not render.
