FxPlug- id<MTLTexture> sourceTexture

• (BOOL)renderDestinationImage:(FxImageTile *)destinationImage sourceImages:(NSArray<FxImageTile *> *)sourceImages pluginState:(NSData *)pluginState atTime:(CMTime)renderTime error:(NSError * _Nullable *)outError { //。。。。。。其他代码 id<MTLTexture> sourceTexture = [sourceImages [ 0 ] metalTextureForDevice:[deviceCache deviceWithRegistryID:deviceRegistryID]]; //。。。。。。其他代码 // Clean up [commandEncoder endEncoding]; [commandBuffer commit]; [commandBuffer waitUntilScheduled]; [colorAttachmentDescriptor release]; [deviceCache returnCommandQueueToCache:commandQueue];

  self.texture = [sourceImages [ 0 ] metalTextureForDevice:[deviceCache deviceWithRegistryID:deviceRegistryID]]; return YES;

} 当我用self.texture 渲染到MTKView的时候，在Motion中显示出来非常模糊。
