Chorus flower models are incredibly unoptimized and cause serious rendering lag
The bug
The chorus flower is perhaps one of the most unaccountably unoptimized models in the game: the shape of the block is specified via 31 texture planes, when a visually identical result can be achieved using just 18. The effects of this can be felt very, very easily.

The bug
The block model file chorus_plant.json is used for defining the item form of chorus plants (MC-120420 incorrectly asserted that it was unused, which it is not). However, this model file completely redefines the chorus plant model shape, which makes it among the largest model files in the game (even more so due to MC-262641). There is no point in doing this, since it can simply reference the chorus flower template model with the chorus plant template file for a visually identical result.
A fixed version of this model is attached which does this - chorus_plant.json can be easily replaced with this attached model to resolve this issue. Mojang have my full permission to use it, if that's required.

The bug
The current multipart system for walls can use more quads than are necessary to achieve an identical visual result. Making Minecraft render more quads increases render lag, so decreasing the amount needed will improve performance.
The case in question is much the same as MC-267281, arising where two opposite connections of a wall are either both "low" or both "tall". Minecraft, by default, will render one model in each direction, with a total of two. However, the exact same visual outcome can be achieved using a single, continuous model, reducing the amount of quads used for this case from 10 to 6. Since there are no texture mapping issues on walls (unlike MC-109478 and MC-225819/MC-267871), this fix also completely preserves their appearance, so we get no bonus fixes.
How to reproduce
- Create this superflat world:
minecraft:barrier;minecraft:the_void
- Initiate flying mode
/fill -30 -63 -30 30 -56 30 cobblestone_wall
/fill -30 -55 -30 30 -48 30 cobblestone_wall
/tp @s 0 0 0 0 90
- Compare framerates with and without the attached resource pack using F3+2
Expected results
Vanilla's framerates would be ideal.
Actual results
The resource pack gives better results.
How to fix
Adopt the system demonstrated by this resource pack for walls. I give Mojang full permission to use this resource pack to fix this optimization problem.

The bug
Bamboo fences, like other fence types (see MC-267281), are not modelled in a way which is optimal for rendering performances. As a result, areas which use large amounts of bamboo fences will decrease framerate much more than otherwise should be the case.
Bamboo fences use a fundamentally different system for modelling compared to other fences, which is why I'm reporting this separately from the other fences. Tragically the issues with the normal fence model have carried over to the system used for bamboo fences.
The model system bamboo fences use is also more complicated than is neccessary - it uses four models for orthogonal connections, whereas this optimized system achieves a visually identical outcome using just three.
Note that since bamboo models use a unique texture rather than just copying the bamboo planks texture, the texture mapping will need to be shifted around. A modified version is found within the attached resource pack - the visual outcome will be identical, but existing resource packs will need to be changed by their authors to fit around it (assuming they don't take the lazy route and just copy over the old, terrible models).
How to reproduce
- Create a creative Superflat world with the following preset:
minecraft:barrier;minecraft:the_void
- Enter flying mode by double pressing the jump button
- Run the command
/tp @s 0 -20 0 0 90
- Run the command
/fill -30 -63 -30 30 -56 30 bamboo_fence
- Open the performance graphs via F3+2
- Switch between the default resources and the attached resource pack, comparing the performance
Expected results
Good framerates in vanilla.
Actual results
We can do far better.
How to fix
Simply implement the resources in the attached resource pack into vanilla. I give Mojang my full permission and encouragement to use these files to make vanilla Minecraft run better.
Further notes
Mipmapping will be affected, however this is a non-issue.
The bamboo fence item model is also updated to fit the new system.
Many of the old model files can be safely deleted once the new ones are added, as this improved system renders them completely superseded.
