anchor point parenting is not working

Hello,

 

I am following one tutorial (cant attached, paid, I will end up in  jail).

 

I exactly did what the teacher does. I applied transform effect to a layer and place anchor point from transform effect panel in a specific point (to rotate it from that point). Later I whipped position to the anchor point so that anchor point  follows position.

 

In the tutorial The anchor point remain attached with the shape layer no matter what the teacher does, rotate, move ect. But the  anchor point in my comp does not listen to my command. It stays like as if position is not attached to the anchor point. Anchor point stays fixed where I put it, it does not move if I move or rotate with the shape layer, but in tutorial it does exacltly the opposite, There the anchor point moves with the shape layer, there it is not fixed.

 

I dont understand what is wrong with my shape layer and its anchor point. please guide me.

If you tie the Effect/Transform/Position to the Effect/Transform/Anchor point, changing the Effect/Transform/Position value will not move the layer in the frame, but it will move the center of rotation (and scale). To move the layer in the frame, you need to move the layer/Transform/Position or the layer/Transform/Anchor point.  Moving the layer/Transform/Anchor Point also changes the center of rotation (and scale). It looks like that is exactly what is going on in your comp. 

 

This should all make sense if you start at the top and figure that first, masks are applied, then effects, then the layer/Transform properties, and finally, the Layer Styles.

 

Your comp is behaving normally. What did you expect to happen? What was the instructor trying to make happen?

Hi Rick,

 

I have attached the tutorial. Kindly see how the bottom left anchor point remain attached with the box when he moves it or rotates. In my case the anchor point is not moving it stays fixed.

Do you have a link to the actual tutorial? The silent GIF is making it quite difficult to follow the set up.  It looks like the creator is using the Transform effect to be able to move the anchor point so that the layer can rotate on the corner.  I'm left wondering why they didn't alter the layer's actual transform properties, which I'm left to assume is because there's another reason.

It's also a little hard to tell from the tutorial gif if the transform effect's position or the layer's position is being keyframed to move the layer.

Hey Cactus I dnt have any link, I am extremely sorry. 

I dnt have any link.

I am writing the whole thing he has told during the demonstration

  • I (he) need to rotate the box from two specific points, I dnt wanna rotate it around the centre where the anchor point is.
  • I (he) wanna rotate the box from the bottom left and bottom right corner.
  • He said he used Transform effect if he wanna rotate, distort any shape from a different point than the anchor point of the very layer itself.
  •  The he applied Transform effect on the box
  • (now the Tranform effects in effects panel) he said- Now the transform effect put the anchor point in the centre of the layer  just like a normal layer would (In the middle of the box), then he drag the anchor point from effects panel and said ‘ but if I move the anchor point (He is dragging the anchor point from effects panel while saying…) you  see the contents of the layer are shifting with in it, what we need to do is actually tie the position to the anchor point so wherever the anchor point goes the position value follows it.
  • The he takes the property pick whip of the position and drag attached it to the anchor point, he said, Now after effects will tie the position value to the anchor value vie an expression.
  • Now where ever the anchor point goes the position value goes with it
  • So I can put my anchor point wherever I need to and it will alwys appear correct
  • Then he put the anchor point bottom left.
  • Then he rotate the box and put keyframes.

 

My problem starts from here. He can rotate and move the box and the anchor point remain attached in that  bottom left corner.

Mine does not.

My anchor point stays it does not move or rotate with the box. But in his comp it remain attached in the left corner of the box until he moves it manually in the bottom right corner.

What He also did  is,  He zeroed the box layer position by  attaching it with a null. and he also put the anchor point very precisely, measuruing the box (shape layer size 500x 500) and the comp size.

I think am making mistakes here.

 

I am doing it casually, not like him. I think I need to zero the layer position and need to be precise with the anchor point
