In Canvas Studio, a Rect Area Light acts like a softbox in a photo studio: a flat, rectangular emitter that spreads light evenly across its surface. Because every pixel on the panel contributes to the illumination, the light produces broad, natural-looking highlights and velvety soft shadows, perfect for product renders, interior scenes, or any shot that needs flattering, diffuse lighting.
color – sets the hue of the panel; use daylight whites for realism, warm tones for cozy interiors, or bold colors for stylized rim lights.
intensity – overall brightness of the emitter; higher values punch stronger highlights, while lower values give subtle fill.
width – horizontal size of the light in scene units; larger panels create wider, softer illumination.
height – vertical size of the panel; pair with width to match softbox or window proportions.
showHelper – toggles a viewport gizmo that outlines the panel, making it easy to position and aim.
position – XYZ coordinates where the panel sits in 3-D space.
rotation – orientation of the panel; tilt and swivel it to aim light just like adjusting a studio softbox.
Rect Area Lights give you studio-quality softness without complex light rigs: just size the panel, set its intensity and color, and watch surfaces pick up gentle, wraparound highlights that bring out form without harsh edges. Furthermore, with showHelper turned on, you also get a sharp, light-emitting plane that can double as a design element or prop in the scene itself.
