◆ AddMorphTarget()

void AZ::Render::SkinnedMeshInputBuffers::AddMorphTarget	(	uint32_t	lodIndex,
		const RPI::MorphTargetMetaAsset::MorphTarget &	morphTarget,
		const RPI::BufferAssetView *	morphBufferAssetView,
		const AZStd::string &	bufferNamePrefix,
		float	minWeight,
		float	maxWeight
	)

Add a single morph target that can be applied to an instance of this skinned mesh Creates a view into the larger morph target buffer to be used for applying an individual morph Must call Finalize after all morph targets have been added

Parameters

lodIndex	The index of the lod modified by the morph target
morphTarget	The metadata that has info such as the min/max weight, offset, and vertex count for the morph
morphBufferAssetView	The view of all the morph target deltas that can be applied to this mesh
bufferNamePrefix	A prefix that can be used to identify this morph target when creating the view into the morph target buffer.
minWeight	The minimum weight that might be applied to this morph target. It's possible for the weight of a morph target to be outside the 0-1 range. Defaults to 0
maxWeight	The maximum weight that might be applied to this morph target. It's possible for the weight of a morph target to be outside the 0-1 range.

◆ Finalize()

void AZ::Render::SkinnedMeshInputBuffers::Finalize ( )

Do any internal calculations that must be done after the input buffers are created from the model and after all morph targets have been added

◆ GetMorphTargetIntegerEncoding()

float AZ::Render::SkinnedMeshInputBuffers::GetMorphTargetIntegerEncoding	(	uint32_t	lodIndex,
		uint32_t	meshIndex
	)		const

Return the integer encoding used for the morph targets for a given lod/mesh, or -1 if there are no morph targets for the mesh. If the values are not yet pre-calculated, they will be when calling this function
