IBakedModel is the result of calling
IModel, which purely represents a shape without any concept of items or blocks,
IBakedModel is not as abstract; it represents geometry that has been optimized and reduced to a form where it is (almost) ready to go to the GPU. It can also process the state of an item or block to change the model.
In a majority of cases, it is not really necessary to implement this interface manually. One can instead use one of the existing implementations.
ItemOverrideList to use for this model. This is only used if this model is being rendered as an item.
If the model is being rendered as a block in the world, the block in question does not emit any light, and ambient occlusion is enabled, this causes the model to be rendered with ambient occlusion.
If the model is being rendered as an item in an inventory, on the ground as an entity, on an item frame, etc. this makes it look “flat.” In GUIs this also disables the lighting.
Unless you know what you’re doing and are OK with using deprecated features, just
return false from this and continue on.
When rendering this as an item, returning
true causes the model to not be rendered, instead falling back to
TileEntityItemStackRenderer::renderItem. For certain vanilla items such as chests and banners, this method is hardcoded to copy data from the item into a
TileEntity, before using a
TileEntitySpecialRenderer to render that TE in place of the item. For all other items, this queries a registry to find the
Class<? extends TileEntity> corresponding to the item, finds the
TileEntitySpecialRenderer<T> for that, and renders that in place of the model itself.
ForgeHooksClient::registerTESRItemStack is used to register this kind of mapping. When a TESR is called like this, it receives
null as it’s
Whatever texture should be used for the particles. For blocks, this shows when an entity falls on it, when it breaks, etc. For items, this shows when it breaks or when it’s eaten.
Deprecated in favor of implementing
handlePerspective. The default implementation is fine if
handlePerspective is implmented. See Perspective.
This is the main method of
IBakedModel. It returns
BakedQuads, which contain the low-level vertex data that will be used to render the model. If the model is being rendered as a block, then the
IBlockState passed in is non-null. Additionally,
Block::getExtendedState is called to create the passed
IBlockState, which allows for arbitrary data to be passed from the block to the model. If the model is being rendered as an item, the
ItemOverrideList returned from
getOverrides is responsible for handling the state of the item, and the
IBlockState parameter will be
EnumFacing passed in is used for face culling. If the block against the given side of the block being rendered is opaque, then the faces associated with that side are not rendered. If that parameter is
null, all faces not associated with a side are returned (that will never be culled).
Note that this method is called very often: once for every combination of non-culled face and supported block render layer (anywhere between 0 to 28 times) per block in world. This method should be as fast as possible, and should probably cache heavily.
long parameter is a random number.
