texture update in camera view

Hello,

When importing 2 “movies (or image sequences) as planes”, i cannot see the textures being updated on both planes at the same time.
Indeed i have to select one plane and click the material or texture tab to see the texture being updated in the camera view.

Is there a parameter to say “keep all textures of all objects updated in real time in camera view” ?

Thanks :eyebrowlift:
