I’m testing a driver because I want to use the texture toggle feature for scenes with many objects.
However, it works internally, but the results are not updated in the viewport.
The renderer selection window must be clicked again to update it.
There is no change in mode change or timeline scrub.
Could the driver’s results be displayed in real time in the viewport with only the motion of the left plane?
Thank you for reading.
Try toggling the color influence. If you had added a .blend file it would make helping you much easier.
Thanks for the ripple 
I tried both of the drivers in the influence check box and value box.
but Unfortunately, the result was the same as the GIF I attached. 
That’s odd. I was sure it was possible. Since you added no example .blend file, I had to set up the example myself to test further. Seems drivers on material settings work in realtime, but drivers on texture settings don’t work at all.
Right. I just need to click on the renderer selection button after manually moving the driver controller. Thanks for the answer.
