# makeRenderCommandEncoder(descriptor:options:) Creates a render command encoder from a render pass descriptor with additional options. ``` func makeRenderCommandEncoder(descriptor: MTL4RenderPassDescriptor, options: MTL4RenderEncoderOptions = []) -> (any MTL4RenderCommandEncoder)? ``` ## Parameters `descriptor` Descriptor for the render pass. `options` [`MTL4RenderEncoderOptions`](/documentation/Metal/MTL4RenderEncoderOptions) instance that provide render pass options. ## Return Value The created [`MTL4RenderCommandEncoder`](/documentation/Metal/MTL4RenderCommandEncoder) instance, or `nil` if the function fails. ## Discussion This method creates a render command encoder to encode a render pass, whilst providing you the option to define some render pass characteristics via an instance of [`MTL4RenderEncoderOptions`](/documentation/Metal/MTL4RenderEncoderOptions). Use these options to configure suspending/resuming render command encoders, which allow you to encode render passes from multiple threads simultaneously. --- Copyright © 2026 Apple Inc.
