WriteSASSET()

bool Spices::MeshLoader::WriteSASSET ( int folderIndex, const std::string & fileName, const MeshPack * outMeshPack )

staticprivate

Write the read data to the sasset file.

Parameters

[in]	fileName	Mesh file path in disk.
[in]	folderIndex	Index of Resource Folder.
[in,out]	outMeshPack	mesh pack pointer, only pass this to it.

Returns

Returns true if write data successfully.
