In the previous movie, we showed the core technique of how to make one 3D…layer in After Effects appear to be projected onto others. In the next two…movies, we're going to show you how to improve the final composite. In this one, …we're going to show you how to make that projection either softer or…sharper and then in the final movie we're going to show how to clean up that…light leak that was around the projected image. So let's dive in.…In the previous movie, we set the combination of a light and a layer so that we…could project that layer's image onto other 3D objects inside my world.…
The first thing you might notice is that I'm seeing just the wall where this light is…projecting on it and I'm not seeing any more of my wall or my floor.…Quite often when you're building a seam like this you will want to add at least…one more light to the seam to help fill out your illumination of your overall…world. In this case, I'm going to create an ambient light, which creates a…gentle overall illumination. I'm going to set a lower intensity of say 20%…
Projecting one 3D layer onto another is useful for creating film and video projections as well as stained glass effects. In After Effects: Light Transmission, instructor Chris Meyer demonstrates the required steps, including mastering shadows and the Light Transmission parameter. He teaches numerous tips and tricks for building 3D worlds (including using seamless tiles), grouping together layers and lights, softening or sharpening projections, and using "negative light" to remove unwanted light leaks from a scene.
