A group of batches.

Represents a container for multiple batches that share the same culling method. Additional resources: OnPerformCulling

BatchRendererGroup is an experimental API originally designed for DOTS Hybrid Renderer use only. This API is under construction and several public methods will be deprecated. The goal is to improve the API to make it usable for more than just the DOTS Hybrid Renderer. The current API is going be replaced with a new API in 2022.1.


BatchRendererGroupCreates a new BatchRendererGroup.

Public Methods

AddBatchAdds a new batch to the group.
DisposeDeletes a group.
EnableVisibleIndicesYArrayEnables or disables BatchCullingContext.visibleIndicesY.
GetBatchMatricesRetrieves the matrices associated with one batch.
GetBatchMatrixArrayRetrieves an array of instanced vector properties for a given batch.
GetBatchScalarArrayRetrieves an array of instanced float properties for a given batch.
GetBatchScalarArrayIntRetrieves an array of instanced int properties for a given batch.
GetBatchVectorArrayRetrieves an array of instanced vector properties for a given batch.
GetBatchVectorArrayIntRetrieves an array of instanced int vector properties for a given batch.
GetNumBatchesRetrieves the number of batches added to the group.
RemoveBatchRemoves a batch from the group. Note: For performance reasons, the removal is done via emplace_back() which will simply replace the removed batch index with the last index in the array and will decrement the size. If you're holding your own array of batch indices, you'll have to either regenerate it or apply the same emplace_back() mechanism as RemoveBatch does.
SetBatchBoundsSets the bounding box of the batch.
SetBatchFlagsSets flag bits that enable special behavior for this Hybrid Renderer V2 batch.
SetBatchPropertyMetadataSets all Hybrid Renderer DOTS instancing metadata for this batch, and marks it as a Hybrid Renderer V2 batch.
SetInstancingDataUpdates a batch.


OnPerformCullingCulling callback function.
