Sale controls opacity

Hi

I have 11 short interviews that will scale and fill the screen at different times. The design is below each person is a separate layer Comp.

Each layer starts as part of a group then fills the screen then returns to its original position in the group.

This is then repeated 11 times.

As they fill the screen I want the background layers to fade out. I want the scale of one layer to change the opacity of other layers both above and below it in the layer order.

This is where I need help, I thought I could use a Slider attached to the scaling layer. Then parent the opacity on other layers so it reduces their opacity to 40%. Issue I have I cannot change the parenting on the other layers when it is their turn to become full screen when they are already parented to another layer.

Looking for help and maybe alternative ways of approaching this.

Thanks

Mike

Correct answer P.M.B

What he wants to do is have all the other blocks opacity fade down to 40% as one block scales up.

But he needs every block to scale up and down in succession. So the block that was the leader becomes the follower and the block that was the follower becomes the leader...in succession.

So as block A scales up, block B,C,D & E  opacity fades down to 40%...then back up to 100% as Block A scales back down.

When Block B scales up, blocks A,C,D,E opacity fades down to 40% then back up as B scales back down

When Block C scales up, blocks A,B,D,E opacity fades down to 40% ...etc.....

Basically whatever block is scaling...all the other blocks opacity should follow

I think you want a linear expression on the opacity.

I think this video does a decent job explaining the linear expression.

Example number 2 is probably the one most pertinent

Hi

Thanks for the link and reply - apologies for the miss spelling in the title.

I can see the principle, but it has to be the scaling layer that effects the layer opacity layer. All layers scale as each person speaks, therefore the scaling layer needs to act as the control. Opacity layers cannot be parented to the scaling layer. All layers need to scale and also be made to fade out.

Hope thats clear.

Thanks for your help.

So in the example where he has the position drive the rotation,  replace position with scale and replace rotation with opacity.
