A plugin can create a 2D image/texture of a 3D OpenGL scene - I gather this will appear in Motion 3 as a textured 2D plane (rather than a true 3D object) when in 'perspective' view (not the camera view). Is it correct to say that the use of Fx3DAPI (getting camera matrix, layer matrix) will allow the plugin to correctly change the viewing orientation of its rendered 3D scene such that as far as a moving camera in Motion 3 is concerned it looks like a 3D object? Am I right in assuming layers can be set up to always face the camera?
Thanks for any comments.
It sounds like you're thinking about this problem in the way that After Effects plugins approach the problem. Motion works a little differently than that. With Motion, you would probably want to apply the effect to a 3D layer which follows the camera, rather than a 2D layer. Currently, with a 2D Layer, the camera transform returned by the Fx3DAPI is always a camera at <0,0,0> and facing the layer. (Maybe we should change that to be more like After Effects, where it gives you the 3D camera transform regardless? I haven't gotten much feedback on how this should work, so if you have an opinion, let me know quickly, please!)
