how to achieve the hula effect ????

First, make sure that your 3D stroke is positioned so it has Z depth. Meaning it shouldn’t be almost vertical. It should have some distance from it’s front to back in Z space.

Second, make sure on your top layer (remeber a layer is the whole thing, Solid, mask, 3D stroke effect) that you are changing the ‘z clip BACK parameter’ so that it only leaves the front of your stroke.

So in my example the layer that sits on top of the characters head will maybe have parameters of:

Z clip front = 0
Z clip back = 1200 (if let’s say a value of 1200 chopped your layer’s depth in half).

This would then only leave the front half of the stroke visible (from 0 to it’s halfway point 1200)

Then Duplicate the entire layer that 3D stroke is on (not the effect whithin a layer). So that you have another AE layer (including the solid and 3D stroke effect applied to it)

Put this Duplicate layer below our earthlink head layer.

In that go into the 3D stroke effect and you would change the parameters to this:

Z clip front = 1200
Z clip back = 30000 (or whatever the highest number is)

That way it will chop off the front of the stroke.

Remeber that 1200 here is an arbitrary number I picked. You have to adjust the numbers till your stroke is getting chopped off half way through it’s depth.

Maybe I am not following correctly.

But cannot you just drop in your image layer, make it 3D and put it at say…320,243,100
THEN create your circle/3D stroke layer and make that 3D, and put it at the same place only with an x rot of 90

The stroke should automatically go around the other layer and clip properly due to AE’s 3D capabilities….

or did I miss something?

It doesn’t when I do it. As far as I know just like 3D invig, 3D stroke doesn’t truly exist in AE 3D space. It is a 2D layer effect that uses the info from the AE camera to simulate the correct angles and such. But to break it into layers, you need to do it in a 2D approach using layer stacks.

Like John Dickenson’s recent 3D invig tutorial where he uses flat text along with his 3D invig model. However he still creates the flat text in invig so that it is correctly masked along with the invig model.

3D stroke could have changed recently, but the demo I mess with can only simulate depth thru clipping planes.

Which is why I simulated 3D stroke in Maya and C4D (using particle circle sprites) so that I get true 3D.

hat’s off.

U R correct. Never tried to do it in AE before,…..but yup. You are right.

nevermind 😉
