my code：
guard let drawable = view.currentDrawable else { return }
let renderPassDescriptor = MTLRenderPassDescriptor()
renderPassDescriptor.colorAttachments[0].texture = drawable.texture //There is a crash
renderPassDescriptor.colorAttachments[0].loadAction = .clear
renderPassDescriptor.colorAttachments[0].clearColor = MTLClearColor(red: 0, green: 0, blue: 0, alpha: 0)
error info：
MTLTextureDescriptor has height (9964) greater than the maximum allowed size of 8192. > validateTextureDimensions > validateTextureDimensions:1075: failed assertion `MTLTextureDescriptor has height (9964) greater than the maximum allowed size of 8192.'
please help：
I try to put a canvas on an image，as you can see，the size of this canvas is too large to exceed the GPU processing limit。Is there a better way that don't change size to solve this problem
Look for "Maximum 2D texture width and height" in https://developer.apple.com/metal/Metal-Feature-Set-Tables.pdf
You can check the GPUFamily through MTLDevice API.
As for how to workaround this limitation, I guess you only have two choices:
- use a smaller texture size
- use several textures and display them next to each other like tiles
