After the build 4.2.9. I have a weird bug. It keep crashing and when I read the message, it display validateRenderPassDescriptor:782: failed assertion `RenderPass Descriptor Validation Texture at colorAttachment[0] has usage (0x01) which doesn't specify MTLTextureUsageRenderTarget (0x04) This happen when I run in debug mode and try to hook up the motion template. I found out that the output texture create have usage only "MTLTextureUsageShaderRead" but no "MTLTextureUsageRenderTarget" Anyone have problem like me? I uusing fxplug 4.2.9 motion 5.7 and final cut 10.7.1. running in sonoma 14.2.1

Namaste! I'm putting together a FCPX Effect that is supposed to increase the resolution with AI upscale, but the only way to add resolution is by scaling. The problem is that scaling causes the video to clip. I want to be able to give a 480 video this "Resolution Upscale" Effect and have it output a 720 or 1080 AI upscaled video, however both FxPlug and Motion Effects does not allow such a thing. The FxPlug is always getting 640x480 input (correct) but only 640x480 output. What is the FxPlug code or Motion Configuration/Cncept for upscaling the resolution without affecting the scale? Is there a way to do this in Motion/FxPlug? Scaling up by FxPlug effect, but then scaling down in a parent Motion Group doesn't do anything. Setting the Group 2D Fixed Resolution doesn't output different dimensions; the debug output from the FxPlug continues saying the input and output is 640x480, even when the group is set at fixed resolution 1920x1080. Doing a hierarchy of Groups with different settings for 2D Fixed Resolution and 3D Flatten do not work. In these instances, the debug output continues saying 640x480 for both input and output. So the plug in isn't aware of the Fixed Resolution change. Does there need to be a new FxPlug property, via [properties:...], like "kFxPropertyKey_ResolutionChange" and an API for changing the dest image resolution? (and without changing the dest rect size) How do we do this?

when I try to import MetalFX in visionOS, Xcode show error : No such module 'MetalFX' , but the document show visionOS is supported

Greetings! I have made use of Apple ARKit documentations to create a simple ARKit application which utilizes SceneKit (Tried Metal too) I am currently unsure of how to make use of SmoothedSceneDepth(SceneDepth) in general to acquire the DepthData from the DataMap acquired in the View. is there any particular method or way that I can access this data for displaying the depth. would be grateful with any inputs or suggestions. Thanks in advance

Hi, Is transparency supported in MetalFX? I have a project that sets a texture to a particular alpha value. It works fine. However, as soon as I enable MetalFX, the transparency stops working. The alpha value is set to 1.0. If transparency is supported in MetalFX, how do I enable it? Thank you

I write iOS plug in to integrate MetalFX Spatial Upscaling to Unity URP project. C# Code in Unity: namespace UnityEngine.Rendering.Universal { /// /// Renders the post-processing effect stack. /// internal class PostProcessPass : ScriptableRenderPass { RenderTexture _dstRT = null; [DllImport ("__Internal")] private static extern void MetalFX_SpatialScaling (IntPtr srcTexture, IntPtr dstTexture, IntPtr outTexture); } } void RenderFinalPass(CommandBuffer cmd, ref RenderingData renderingData) { // ...... case ImageUpscalingFilter.MetalFX: { var upscaleRtDesc = tempRtDesc; upscaleRtDesc.width = cameraData.pixelWidth; upscaleRtDesc.height = cameraData.pixelHeight; RenderingUtils.ReAllocateIfNeeded(ref m_UpscaledTarget, upscaleRtDesc, FilterMode.Point, TextureWrapMode.Clamp, name: "_UpscaledTexture"); var metalfxInputSize = new Vector2(cameraData.cameraTargetDescriptor.width, cameraData.cameraTargetDescriptor.height); if (_dstRT == null) { _dstRT = new RenderTexture(upscaleRtDesc.width, upscaleRtDesc.height, 0, RenderTextureFormat.ARGB32); _dstRT.Create(); } // call native plugin cmd.SetRenderTarget(m_UpscaledTarget, RenderBufferLoadAction.DontCare, RenderBufferStoreAction.Store, RenderBufferLoadAction.DontCare, RenderBufferStoreAction.DontCare); MetalFX_SpatialScaling(sourceTex.rt.GetNativeTexturePtr(), m_UpscaledTarget.rt.GetNativeTexturePtr(), _dstRT.GetNativeTexturePtr()); Graphics.CopyTexture(_dstRT, m_UpscaledTarget.rt); sourceTex = m_UpscaledTarget; PostProcessUtils.SetSourceSize(cmd, upscaleRtDesc); break; } // ..... } Objective-c Code in iOS: head file: #import <Foundation/Foundation.h> #import <MetalFX/MTLFXSpatialScaler.h> @protocol MTLTexture; @protocol MTLDevice; API_AVAILABLE(ios(16.0)) @interface MetalFXDelegate : NSObject { int mode; id _device; id _commandQueue; id _outTexture; id _mfxSpatialScaler; id _mfxSpatialEncoder; }; (void)SpatialScaling: (MTLTextureRef) srcTexture dstTexure: (MTLTextureRef) dstTexture outTexure: (MTLTextureRef) outTexture; (void)saveTexturePNG: (MTLTextureRef) texture url: (CFURLRef) url; @end m file: #import "MetalFXOC.h" @implementation MetalFXDelegate (id)init { self = [super init]; return self; } static MetalFXDelegate* delegateObject = nil; (void)SpatialScaling: (MTLTextureRef) srcTexture dstTexture: (MTLTextureRef) dstTexture outTexture: (MTLTextureRef) outTexture { int width = (int)srcTexture.width; int height = (int)srcTexture.height; int dstWidth = (int)dstTexture.width; int dstHeight = (int)dstTexture.height; if (_mfxSpatialScaler == nil) { MTLFXSpatialScalerDescriptor* desc; desc = [[MTLFXSpatialScalerDescriptor alloc]init]; desc.inputWidth = width; desc.inputHeight = height; desc.outputWidth = dstWidth; ///_screenWidth desc.outputHeight = dstHeight; ///_screenHeight desc.colorTextureFormat = srcTexture.pixelFormat; desc.outputTextureFormat = dstTexture.pixelFormat; if (@available(iOS 16.0, *)) { desc.colorProcessingMode = MTLFXSpatialScalerColorProcessingModePerceptual; } else { // Fallback on earlier versions } _device = MTLCreateSystemDefaultDevice(); _mfxSpatialScaler = [desc newSpatialScalerWithDevice:_device]; if (_mfxSpatialScaler == nil) { return; } _commandQueue = [_device newCommandQueue]; MTLTextureDescriptor *texdesc = [[MTLTextureDescriptor alloc] init]; texdesc.width = (int)dstTexture.width; texdesc.height = (int)dstTexture.height; texdesc.storageMode = MTLStorageModePrivate; texdesc.usage = MTLTextureUsageRenderTarget | MTLTextureUsageShaderRead | MTLTextureUsageShaderWrite; texdesc.pixelFormat = dstTexture.pixelFormat; _outTexture = [_device newTextureWithDescriptor:texdesc]; } id upscaleCommandBuffer = [_commandQueue commandBuffer]; upscaleCommandBuffer.label = @"Upscale Command Buffer"; _mfxSpatialScaler.colorTexture = srcTexture; _mfxSpatialScaler.outputTexture = _outTexture; [_mfxSpatialScaler encodeToCommandBuffer:upscaleCommandBuffer]; // outTexture = _outTexture; id textureCommandBuffer = [_commandQueue commandBuffer]; id _mfxSpatialEncoder =[textureCommandBuffer blitCommandEncoder]; [_mfxSpatialEncoder copyFromTexture:_outTexture toTexture:outTexture]; [_mfxSpatialEncoder endEncoding]; [upscaleCommandBuffer commit]; } @end extern "C" { void MetalFX_SpatialScaling(void* srcTexturePtr, void* dstTexturePtr, void* outTexturePtr) { if (delegateObject == nil) { if (@available(iOS 16.0, *)) { delegateObject = [[MetalFXDelegate alloc] init]; } else { // Fallback on earlier versions } } if (srcTexturePtr == nil || dstTexturePtr == nil || outTexturePtr == nil) { return; } id<MTLTexture> srcTexture = (__bridge id<MTLTexture>)(void *)srcTexturePtr; id<MTLTexture> dstTexture = (__bridge id<MTLTexture>)(void *)dstTexturePtr; id<MTLTexture> outTexture = (__bridge id<MTLTexture>)(void *)outTexturePtr; if (@available(iOS 16.0, *)) { [delegateObject SpatialScaling: srcTexture dstTexture: dstTexture outTexture: outTexture]; } else { // Fallback on earlier versions } return; } } With the C# and objective code, the appear on screen is black. If I save the MTLTexture to PNG in ios plug in, the PNG is ok(not black), so I think the outTexture: outTexture write to unity is failed.

I have tested SpatialUpsacling with a Unity URP sample project: https://github.com/mao-test-h/MetalFXSamples. I used iPhone 13 with iOS Beta 7. The performance and quality are both worse than Native.

I use Macmini with MacOS Ventura 13.3.1, while the Mac running MetalFX sample code, and choose Temporal Scaler, makeTemporalScaler return nil value, and print "The temporal scaler effect is not usable!". If i choose SpatialScaler, it is ok. guard let temporalScaler = desc.makeTemporalScaler(device: device) else { print("The temporal scaler effect is not usable!") mfxScalingMode = .defaultScaling return } Sample code: https://developer.apple.com/documentation/metalfx/applying_temporal_antialiasing_and_upscaling_using_metalfx?language=objc

In my game project, there is a functions.data file in then /AppData/Library/Caches/[bundleID]/com.apple.metal/functions.data, when we reboot and launch the game, this file was rest to about 40KB, normaly this file's is about 30MB, this operation was done by the metal, Is there any way to avoid it?
