# makeTexture(descriptor:offset:) Creates a texture at a specified offset on the heap. ``` func makeTexture(descriptor: MTLTextureDescriptor, offset: Int) -> (any MTLTexture)? ``` ## Parameters `descriptor` A descriptor object that describes the properties of the texture. `offset` The distance, in bytes, to place the texture relative to the start of the heap. ## Return Value A new texture, or `nil` if the heap is not a placement heap. ## Discussion You can call the method with the following restrictions: - The heap’s type needs to be [`MTLHeapType.placement`](/documentation/Metal/MTLHeapType/placement) - The texture’s CPU cache mode option needs to match the heap’s [`cpuCacheMode`](/documentation/Metal/MTLHeap/cpuCacheMode) property - The texture’s storage mode option needs to be [`MTLStorageMode.memoryless`](/documentation/Metal/MTLStorageMode/memoryless), or match the heap’s [`storageMode`](/documentation/Metal/MTLHeap/storageMode) property > Important: > Avoid potentially erratic behavior by aligning the texture correctly > so that it doesn’t extend past the end of the heap. Use the [`heapBufferSizeAndAlign(length:options:)`](/documentation/Metal/MTLDevice/heapBufferSizeAndAlign(length:options:)) to determine the correct size and alignment. > Note: > The new texture can implicitly alias the underlying memory of other resources already in the heap within the overlapping half-open range of `[offset, offset + requiredSize)`. --- Copyright © 2026 Apple Inc.
