Part 2: After Effects: creating the glint pass
Import the two files we've created with Cinema 4D into After Effects and create a new project that includes both of them. If you're using different footage, be sure you've isolated the subject you want to apply the glint to by using some type of masking method.[an error occurred while processing this directive]Next, we'll add a solid that will represent our simple glint pass. With After Effects 5.x+, you can use lights in your composition to create a similar look. In addition, the lights allow you to cast shadows onto other layers (for another tutorial).

Draw a mask on your solid in the shape of your light pass. Drawing a mask, rather than resizing your layer, allows you to control the shape, feather, opacity and expansion of your light (another benefit over 3D lights).



Add a bit of feather to the mask and change the transfer mode to Add.



To animate the mask across the comp, set a keyframe for mask shape. Click on the stopwatch to add a keyframe at frame 0. Select the mask and move the points to the left. Goto the end of the comp (end) and move the points to the other side of the screen.
