1. Pre-compose the 3D layer you want to use with Stencil Alpha. Choose to leave all attributes in the parent comp.
2. Go inside the pre-comp and enable 3D on the layer.
3. Enable collapse transformations on the pre-comp and apply any effect to the pre-comp (a blur, for example, with zero radius, or a levels effect without changing any values), this will allow you to choose a blend mode for the (partially) collapsed pre-comp.
4. Make sure the pre-comp’s blend mode is set to Stencil Alpha.
Here’s an example:

[karin weduwer] “ps. floating point is 32.”
Indeed, floating point is 32 bits per channel, but I’m curious what the actual floating point color values on the layers are. For example:
Red: 1.0
Green: 1.0
Blue: 1.0
Alpha: 1.0That would be a pure white color with full opacity. If any of the RGB values are above 1.0 then those values will be truncated/clipped to 1.0 when you render to a non-floating point format. That can cause the colors to look different.
It sounds, though, like FCP X is set up to blend in a linearized working space so that seems to have addressed your issue.

There’s a drop down in the displacement map effect that allows you to change how the map is applied. I believe the default is stretch to fit and it sounds like center map may have worked for you.

Are there any other effects applied to the layers?
It might be easier to examine the issue if you upload the scene file with proxy/simplified assets.

There’s a checkbox under the area where you set the working color profile that allows you to linearize the profile.
What are the floating point color values of your titles, and why are they set to multiply in AE?

Are any of the layers continuously rasterized?

You mention that you’re working in 32bpc. What are the floating point color values of your titles in AE? Are you also linearizing the working space?

A radial blur might give you a finer degree of control. You could tie the amount of blur to the rotation speed using an expression.

The PSD file provided on that page is not using a linear profile. As you’ve already discovered, if you want your AE results to match PSD then you need to not linearize your profile.
It looks to me like whoever produced those render elements was not rendering them for a linear workflow. They were not intended to be used in a linear workflow. As a result they, erm, won’t work in a linear workflow.

Newton is a great suggestion in this case. Though if you’re interested in using more than one ‘anchor point’ in the future you can parent your layer to a series of Nulls, each one can serve as a center of rotation.
