How do I hold one drawing for multiple frames
I'm creating an animation that has two layers, on the first layer there is a static drawing of a fence on frame one and on the second layer I have an animated character with multiple keyframes along the timeline. I need to hold the single drawing on the first layer for the duration of the timeline. I don't see a simple way to do this. I tried dragging the keyframe to happen over multiple frames - nope. I tried looking for an interpolation setting - nope. Do I actually have to copy and paste the single drawing for every frame for it to be held? What if I want to change the single drawing, will I have to copy and paste the drawing over again?
A bit confused on the workflow here, any advice?
Thanks.
