Assets/Standard Assets/Image Effects (Pro Only)/CameraMotionBlur.js(102,20): BCE0005:

“Assets/Standard Assets/Image Effects (Pro Only)/CameraMotionBlur.js(102,20): BCE0005: Unknown identifier: ‘supportDX11’.”

Suddenly this problem showed up when I’m trying to Play my scene, and I have no idea to fix it. My whole project seems like it has problems now. I’m new to Unity.

Thanks!

More info:
function CheckResources () : boolean {
CheckSupport (true, true);
motionBlurMaterial = CheckShaderAndCreateMaterial (shader, motionBlurMaterial);
if(supportDX11 filterType == MotionBlurFilter.ReconstructionDX11) {
dx11MotionBlurMaterial = CheckShaderAndCreateMaterial(dx11MotionBlurShader, dx11MotionBlurMaterial);
}
