wpf - Is there a way to make custom shader effect properties animatable inside Blend?

Question

Custom shader properties cannot be seen on the Blend UI such as in picture below :

By looking at source of DropShadowEffect (which is part of WPF), animatable properties have been defined like this :

DropShadowEffect.ShadowDepthProperty = Animatable.RegisterProperty(...);

Unfortunately, Animatable.RegisterProperty method is internal what forbids doing so, the only way working is to manually code a storyboard.

Is there a way or a library that would allow to have this ability back for custom shaders ?

找到问题的根源：着色器的URI不完整！

它应该是这样的：

var pixelShader = new PixelShader();
pixelShader.UriSource = new Uri(@"pack://application:,,,/YourAssembly;component/YourEffect.ps", UriKind.Absolute);

微妙：不要忘记@
