What we experience is entirely dependent on context. Our eyes are amazingly adaptive – we can see a broad range of amounts of light as “bright” and even a broad range of colors as “white”. 💡 So, what’s the deal with photometrics? Because Eevee can’t use nodes yet, the lumens, color temperature, & spot angle values can only be adjusted upon creation and IES textures will not be applied. They’re also automatically placed above the height of the camera for convenience.Īrea lights have a Spread Angle property to control how much light is directed forwards.Īll lights can be used in Eevee but are more convenient to use in Cycles. Sun presets can be created with a corresponding sky that’s automatically linked to the sun’s rotation. Spot lights produce the same amount of light regardless of their spot angle, so tightening the beam will actually focus the light, unlike Blender’s default. You can set the scene’s exposure to match the newly added preset with one click. The number of lumens will be the same regardless of the color selected, so a blue light and a red light will appear equally bright.Īdjusting a normal Blender light with constant watts makes some colors appear darker than others:Īdjusting a photometric light with constant lumens keeps the perceptual brightness about the same (explanation below):Ī lumens conversion node group is appended if Use Nodes is enabled, which can be used for any type of light in Cycles including mesh lights. You can set an RGB color instead of a Kelvin value if desired. There are also over 30 IES presets that cast believable patterns according to how each bulb is actually used, for a total of over 60 presets.Įach light’s strength can be adjusted in lumens instead of watts (explanation below.Įach light has a preset Kelvin color temperature based on its real world source, which can be easily adjusted. There are over 30 plain point, spot, area, and sun presets in total.
Here’s what you can expect:Īll lights are based on real world light fixtures and are organized by type and strength.
