Constructors

SkinnedMesh()

Initializes a new instance of the SkinnedMesh.

Declaration
public SkinnedMesh()

Properties

ParentSkinnedModel

Gets the parent model asset.

Declaration
public SkinnedModel ParentSkinnedModel { get; }
Property Value
SkinnedModel

Methods

DownloadVertexBuffer(Boolean)

Downloads the raw vertex buffer that contains mesh vertices data. To download data from GPU set forceGpu to true and call this method from the thread other than main thread (see IsInMainThread). [Deprecated in v1.10]

Declaration
public SkinnedMesh.Vertex[] DownloadVertexBuffer(bool forceGpu = false)
Parameters
System.Boolean forceGpu

If set to true the data will be downloaded from the GPU, otherwise it can be loaded from the drive (source asset file) or from memory (if cached). Downloading mesh from GPU requires this call to be made from the other thread than main thread. Virtual assets are always downloaded from GPU memory due to lack of dedicated storage container for the asset data.
Returns
SkinnedMesh.Vertex[]

The gathered data.

DownloadVertexBuffer0(Boolean)

Downloads the first vertex buffer that contains mesh vertices data. To download data from GPU set forceGpu to true and call this method from the thread other than main thread (see IsInMainThread). [Deprecated in v1.10]

Declaration
public SkinnedMesh.Vertex0[] DownloadVertexBuffer0(bool forceGpu = false)
Parameters
System.Boolean forceGpu

If set to true the data will be downloaded from the GPU, otherwise it can be loaded from the drive (source asset file) or from memory (if cached). Downloading mesh from GPU requires this call to be made from the other thread than main thread. Virtual assets are always downloaded from GPU memory due to lack of dedicated storage container for the asset data.
Returns
SkinnedMesh.Vertex0[]

The gathered data.

UpdateMesh(Float3[], Int32[], Int4[], Float4[], Float3[], Float3[], Float2[], Color32[])

Updates the skinned model mesh vertex and index buffer data. Can be used only for virtual assets (see IsVirtual and CreateVirtualAsset<T>()). Mesh data will be cached and uploaded to the GPU with a delay.
