I want this text to integrate better with this scene.…And one way to do that would be to have it cast shadows on the face …of the building behind it.…To do that, I need to have a layer attracts the face of this building …that receives shadows from the text.…So I'm going to select the 3D Camera Tracker effect apply it to my underlying footage, …lasso together some more points here, average them together to…create myself a good Track Point, make some more up there, move my target …roughly where I need the Shadow Catcher to be centered -- the sun seems to be coming…down at this angle - I could hold down Opt on Mac, Alt on Windows and resize it a bit, …but I'm going to be doing a lot more precise sizing later on once…I've created the Shadow Catcher.…
Now that I have my target in place, I right-click and choose …Create Shadow Catcher and Light.…This means two layers will be created;…one is my light from my scene and the other is this layer called Shadow Catcher.…And indeed, you can now see a shadow appear in the scene.…
