…digging deeper into the problem i am realizing that the bigger problem is the positioning of the texture in 3d space. the bump map does not move according to the layers position or the camera movement.

i know i can solve this with a precomposition but i am looking for a cleaner way to work with shape layers that allows me to access all path keyframes.

any suggestions are welcome!

Hi Matt,
I am not to shure about the gravity, but the basic expression setup should be like this:

Apply the puppet tool to your layer, setup the three points as you mentioned. Create two null-objects, “null01” and “null02”. Connect the outer point of the puppet tool via an expression to the position of the corresponding null object. for the middle point use this expression:

x1 = thisComp.layer(“null02”).transform.position[0];
x2 = thisComp.layer(“null01”).transform.position[0];
y1 = thisComp.layer(“null02”).transform.position[1];
y2 = thisComp.layer(“null01”).transform.position[1];
[x1+x2/2,y1+y2/2]

I think you’ll have to add some offset to the x-value (-50? -250?) inside the fomula, but i am not quite shure how to do the gravity…

I hope I could help you a little bit!
