Particular and 3-D space.

[Michael Szalapski]

What are you trying to do? There dozens upon dozens of different possibilities of how you might be wanting to “make it play nicely with other 3d layers.”
I don’t see anything out of the ordinary in the picture you posted, but then, I don’t know what you want it to look like.

Keep in mind that there are several tutorials here on the COW for working with Particular and 3d layers.

(And BTW, don’t turn the Particular layer 3d.)

Particular (and all other 3D camera aware plug-ins) can’t intersect in 3D space with AE’s own 3D layers.
However, Particular offers a very useful trick in this regard – it lets you set a specific AE 3D layer as an “obscuration layer”. This means that particles which are further away from the camera than that specific layer will be obscured by such layer. So, if you set a layer as the one you show in that picture as an obscuration layer, particles will be able to wrap around that layer.

Thanks Adolfo.

Close, but then the whole layer acts as an obscuration layer and not just the visible object. I know AE isn’t a true 3D program but I thought for some reason this would be fairly straight forward. It seems to get the look I’m after would require some masking.

Hello, Paul.
It’s not related to being or not true 3D (to me, “true 3D” means that pixels are composited according to 3d coordinates, which is absoutely the case for AE). The exception is generated by a “3D aware” effect in a 2D layer (such as Particular). The output of these live on a separate 3D universe from AE’s own, and thus you can’t normally have intersection with AE 3D layers. This is why Particular offers the obscuration trick, which is really nice.

I don’t think you need masking. You’re really close. Make sure the Particular layer is above the obscuration layer. And then remember that particles will only be obscured if they are behind the obscuration layer in 3D space (normally along the Z axis, but it depends on the point of view). So, you should be able to have particles wrapping the obscuration layer, rather than just appearing behind.
Sometimes Particular needs you to reset the obscuration layer setting and set it again, because it creates actual layers to do the trick. It’s a bit tricky, but it should work.
