# Mesh and object shader resource preparation commands Assign resources to mesh and object shaders, including buffers, textures, acceleration structures, sampler states, and function tables. ## Discussion Mesh shaders share argument tables for each resource type, such as buffers, textures, and sampler states. Object shaders share their own separate argument tables, distinct from mesh shaders and other shader types. ## Topics ### Assigning buffers for object shaders [`func setObjectBuffer((any MTLBuffer)?, offset: Int, index: Int)`](/documentation/Metal/MTLRenderCommandEncoder/setObjectBuffer(_:offset:index:)) Assigns a buffer to an entry in the object shader argument table. [`func setObjectBuffers([(any MTLBuffer)?], offsets: [Int], range: Range)`](/documentation/Metal/MTLRenderCommandEncoder/setObjectBuffers(_:offsets:range:)) Assigns multiple buffers to a range of entries in the object shader argument table. [`- (void) setObjectBuffers:(id const[]) buffers offsets:(const NSUInteger[]) offsets withRange:(NSRange) range;`](/documentation/Metal/MTLRenderCommandEncoder/setObjectBuffers:offsets:withRange:) Encodes a command that assigns multiple buffers to a range of entries in the object shader argument table. [`func setObjectBytes(UnsafeRawPointer, length: Int, index: Int)`](/documentation/Metal/MTLRenderCommandEncoder/setObjectBytes(_:length:index:)) Creates a buffer from bytes and assigns it to an entry in the object shader argument table. [`func setObjectBufferOffset(Int, index: Int)`](/documentation/Metal/MTLRenderCommandEncoder/setObjectBufferOffset(_:index:)) Updates an entry in the object shader argument table with a new location within the entry’s current buffer. ### Assigning textures for object shaders [`func setObjectTexture((any MTLTexture)?, index: Int)`](/documentation/Metal/MTLRenderCommandEncoder/setObjectTexture(_:index:)) Assigns a texture to an entry in the object shader argument table. [`func setObjectTextures([(any MTLTexture)?], range: Range)`](/documentation/Metal/MTLRenderCommandEncoder/setObjectTextures(_:range:)) Assigns multiple textures to a range of entries in the object shader argument table.
