Making slow progress. I need to do more beginner lessons.

Would it be possible to see an example of looping through all the previous values in this expression so that the rotation continues to increment instead of snapping back?

Thanks

Thanks Dan, I think thats got it.

Thanks Dan. These are two great lessons / exercises in and of themselves.
I’m going to try to actually combine these two things into what I think I’m trying to achieve. I will post back my results.

Hello Dan. Apologies, I believe I didn’t phrase this question well enough. Save I am setting an expression on scale like so (see below)

so that the layer’s width scales between 100% and 10% depending on its position between the two shape layers in the expression below. “Linear” will of course yield a linear result. If the layer was half way between the 2 layers it’s width would be 50%, 3/4 of the way there 75%, etc etc.

But is there a way to replace “linear” with a curve with multiple key frames between 0 and 1, so you could kind of art direct the range of scale values as the layer travels between the two points….

Cheers

a = linear(transform.position[0], thisComp.layer("Shape Layer 1").transform.position[0], thisComp.layer("Shape Layer 2").transform.position[0], 100, 10);
b = transform.position[1];
[a,b]

If you right click on the position channel of a layer (2D or 3D) you can select “seperate dimensions” which breaks out the X, Y and (if its a 3d layer) the Z channel into seperate keyable channels. Once you do that, it does not seem like you can control tangent handles in the comp window. I’m trying to conceptualize it in my head, it might not be possible to adjust channels in that fashion once they are split, but I feel like thats an incorrect assumption.

Thanks Dan, thats got it sorted!

Hey Dan, I’m attaching a screen shot. I agree, it ought to do what yer saying I think.

Thanks Dan. I just have a number of pre comps I have to lay out slightly different type weights in for HD / SD outputs. I was hoping that, depending upon the HD or SD comp that the preComp went into, expressions would either turn on the HD type layers or the SD type layers saving me a duplication of all those preComps just to change type weight.

Thanks for the reply Darby. I’m working on a graphics kit of some broadcast deliverables. I try to keep the compositions extremely simple. There are any number of ways with nulls, splitting the layer, etc I could make this work, but I’m trying to allow the editor to have to adjust two position key frames on one layer. They set point A (say at 1 sec), then move to the second keyframe and set point B (at 2 sec) by adusting B, keyframe C (at 6sec) is automatically equivalant so the animation holds for those 4 secs. Its just one of those times I have marching orders to make this very simple for the editors.

If I have a sec today I’ll post an example.
