Media Texture in UE 4.19.2 is not working

I was using UE 4.18 before and just try to use 4.19.2 currently.

I have been working with FBX which has morph targets in UE and synchronize morph animation with media texture.

I set my media texture on material and edit blueprint to play media player when I press play button

It was working well in 4.18 (there r some sync problem thou) but when I try to use same way in 4.19, the media texture is not working with animation. (Only animation is shown )

and when I turn off the animation, the media texture is just working…

Does anyone know how to deal with this problem???

Just found that there is an option like this in material section .

After clicking this , everything was ok.
