3d layer Y rotation always flat
Hi forum,
How can I get y rotation always look flat wherever I place the layer in comp space?
If I put the layer position in middle comp, yrotation 90 the layer should look flat. I’m not sure how to explain this. Y rotation should be more than 90 or less depending on what x position the layer place.
Please help.
Thanks,

Sounds like you’re talking about this effect:

Thank you for reply,
I made a sample to picture my situation as below
Solid below is corrected yRotation base on Xposition to look side of the layer while Solid above yRotation all 90 degree.

Try this:
w = thisComp.width * thisComp.pixelAspect;
z = (w/2)/Math.tan(degreesToRadians(19.8));
C = [thisComp.width/2,thisComp.height/2,-z];
v = toWorld(anchorPoint) – C;
180 – radiansToDegrees(Math.atan2(v[2],v[0]))Dan

it worked!! Very accurate.
cant believe it so much complex than i thought.i made one using linear(position[0], 0 ,1920, 110, 70) manually and not accurate.
Thanks Dan
