# setObjectBuffers:offsets:withRange: Encodes a command that 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; ``` ## Parameters `buffers` A pointer to a C array of [`MTLBuffer`](/documentation/Metal/MTLBuffer) instances the command assigns to entries in the object shader argument table for buffers. `offsets` A pointer to a C array of unsigned integers. Each element represents the location, in bytes, from the start of the corresponding [`MTLBuffer`](/documentation/Metal/MTLBuffer) element in `buffers` where the object shader argument data begins. See the [Metal feature set tables (PDF)](https://developer.apple.com/metal/Metal-Feature-Set-Tables.pdf) to check for offset alignment requirements for buffers in `device` and `constant` address space. `range` A span of integers that represent the entries in the object shader argument table for buffers. Each entry stores a record of the corresponding element in `buffers` and `offsets`. ## Discussion By default, the texture at each index is `nil`. > Note: > The Swift version of this method is ``doc://com.apple.metal/documentation/Metal/MTLRenderCommandEncoder/setObjectBuffers(_:offsets:range:)``. --- Copyright © 2026 Apple Inc.
