Forge Freeform Demo question, FF applied object- behaves much differently than other 3d objects…
A question for any Forge Freeform experts out there:
I have a 3d scene I’d like to set up using Forge Freeform.
I’ve attempted this, creating a 2d piece of art with Freeform applied. I added a simple camera move over the surface of the object, and it looks pretty snazzy except for one glitch – adding other 3d objects to the scene.
The other objects seem to have their own depth, so that they seem to “slide” along the surface of the Freeform object when the camera moves, instead of staying in place. I do understand that the Freeform layer is not an actual 3d layer, but shouldn’t all 3d objects be sharing the same space if I’m using the “Active Camera” option in the Freeform 3D views menu?
Is there any solution to this? Is there a way to mix the 2 in a way where they occupy the same space?

I’m not sure what you mean except that:
– all layers in AE are flat planes. Like movie screens.
– in 3D space, all those flat movie screens are floating around, separated in the X, Y and Z direction, as seen by the camera.
– 2D layers appear flat to the camera at all times and do not change size or orientation relative to the camera. No change. Nor do they interact with any layers that have had the 3D switch turned on, except to screw up some things when placed between them in the layer stack. 🙂
– any 3D effect in AE, such as Shatter, FF or Invigorator, creates a “movie” of a 3D object on one of those movie screens. In order for that illusion to be maintained, the layer needs to be a 2D layer, flat to camera. Otherwise the layer will look like a movie playing on a movie screen seen from a corner of the room — distorted.
– the perspective changes seen on one of those “3D movie” layers due to camera movement are a trick, where the look of the “3D movie” is mathematically altered due to the position/rotation values of the AE camera.
– so the other layers in AE’s 3D space have no idea what’s going on with this FF “3D movie” layer. They don’t know anything about any depth variation as portrayed on that flat movie screen. They don’t even know the screen exists, for the most part, since it’s on a layer without the 3D switch turned on.
– even if you turned on the 3D switch for the FF layer, the effect would still appear as if displayed on a flat screen, only now it would look like a movie on a flat screen.
– the only way other objects could be affected by the 3D undulations of an FF object would be if the FF plug could accept multiple objects within its own space (like Invig), but unless Chris B. has rewritten the plug, it ain’t gonna happen.Does that make sense?
