The Self Illuminating material is used to create materials that emit light, such as computer monitors, TV screens and LED clock displays. Because Shaderlight uses exposure controls like a camera, you need to specify how bright your self illuminating surface will be. This brightness is usually measured in candela per metre squared (cd/m²). The presets have descriptions of typical objects and their self illuminating brightness. Remember though that just like in real life, if you try and use an LCD Monitor in full sunlight you may not see anything on the screen, you need to take into account just how bright the scene is around your self illuminating object.


Note: In the current version of Shaderlight, self illuminating surfaces don't emit any light into the scene to illuminate other objects



Luminous Paint 0.1 cd/m² – a very low level illumination that will only be seen in the lowest lighting conditions


LED 2 cd/m² – a typical low power LED used as indicators on electrical appliances



10 cd/m²  – a bright LED to provide a more visible indicator


CRT Monitor 150 cd/m² – the brightness of an old style CRT monitor



LCD Monitor 300 cd/m² – the brightness of an LCD computer monitor



Neon Sign 1500 cd/m² – the illumination level of a neon sign will vary


10,000 cd/m² – the high intensities can't necessarily be related to real world objects, but may be of use in a scene (for example, a sports stadium videoboard)


100,000 cd/m²


1,000,000 cd/m²


10,000,000 cd/m²
