What is the 'Luma Matte' track matte option based on?
Answer: The brightness (luminance) values of the matte layer
Luma Matte uses white areas of the matte layer as fully opaque and black areas as fully transparent for the layer below.
Which After Effects effect is best for simulating realistic depth of field blur?
Answer: Camera Lens Blur
Camera Lens Blur simulates optical lens bokeh with iris shape, blade count, and highlight boost controls.
What does the 'Stencil Alpha' blending mode do in After Effects?
Answer: Uses the layer's alpha to cut a hole through all layers below it down to the background
Stencil Alpha punches through all layers below using the layer's alpha channel, revealing the composition background.
Which compositing method in After Effects allows you to re-light CG renders using normal pass buffers?
Answer: EXtractoR with multi-pass EXR files and relighting expressions
Multi-pass EXR workflows bring in normal, diffuse, and specular passes, enabling re-lighting in compositing.
What is 'Render Order' important for when applying multiple effects to a layer?
Answer: Effects are processed sequentially from top to bottom in the Effect Controls panel
After Effects processes effects from top to bottom in the Effect Controls panel, so changing the order changes the visual result.
Which After Effects blending mode makes white pixels transparent and preserves dark pixels?
Answer: Multiply
Multiply blending multiplies layer and underlying pixel values, making white transparent and darkening the composite.
