I have gotten some questions about what the point is with this script, so I am just going to post a little explanation of it here.
One example of where it would be useful, is if you want to add particle effects inside AE instead of in LW. Say you want to add smoke effects to an animation but can’t afford the render time of using HyperVoxels. Just render out the animation without any particle effects or HyperVoxels, place a null in LW of where you want the particles to emit, and then export that to AE and use that as an emitter inside of that application instead.
So if you have a moving locomotive you parent the null to its chimney, export that and the camera. The rendered image sequence from LW would not be 3D but just a plain 2D backdrop of course, with a null and camera that moves correctly according to the rendered sequence.
It is also generally a good workflow to render out passes so you can tweak the end result in AE instead of having to re-render everything. Janus is supposed to be a very good plugin for rendering out passes in LW, but I have not tried it yet myself. http://janus.faulknermano.com/
Also, keep this in mind:
– 1 meter in LW == 100 pixels in AE
– Check that the x, y, z coordinates of the plane in AE is set to the same as the one in LW (with some potential reversal of some axis, but if something is placed at 0,0,0 in LW it should be the same in AE (which it rarely is by default when a layer is set to 3D)
– Make sure the zoom level on the camera matches. In AE it is specified as pixels and degrees in parenthesis ie. (45.2°). Set this zoom to match the horizontal FOV in LW and you should be good to go.
How does this compare to Al Street’s plug-in “POI CAM” which also exports camera data from LW to AE.
I’ve been using POI cam for a while now and it works pretty well. Is yous alot better?
I am getting the script to work successfully at the starting frame, but as the camera pulls back and banks, the bank and pitch seem to get messed up in AE. It looks as though it may be reversed. Am I doing something wrong?
Oh, I forgot to mention that all of my camera settings in AE are matched up to LW’s camera…I think, anyways!!
Nice work. Saved my bacon with this. The Vimeo tutorial is fantastic and makes it so easy.
I just want to say thank you for this brilliant plugin. It works like a charm and opens up a host of possibilities. You Rock! 🙂
