Is there a way, how to change images from image sequence by slider or driver?
I founded the solution, its alittle bit tricky and not fully suported at this time, but.
A) Set a driver to offset in Image texture node set to image sequence:
B) Create an object or custom property, but object responce was better for me, and write #frame to any slider (Z scale in my situation) and tap enter > it create a driver.
C) In offset driver find the scale value from object you set in and the value where is set your image number it must be integer so I rounded it. And voila.
Pros: It can be done.
Cons: In viewport - refresh image is not fully working after change the slider - you can see right result only in render view. In blender 2.80 it is not working at all. But I hope it will be. I am looking forward to make sume flat puppets and re-drawing the phases of hands and faces trough grease pencil it will be awesome.
