-Short paragraph explaining the function of the Irradiance ​stuff here, along with nice picture for eye candy.+Irradiance ​is diffuse reflection and is in Lys calculated as Lambertian diffuse reflection. 
 + 
 +This target can either be exported as an image or alternatively as 9 spherical harmonic coefficients. This provides ​very efficient form of compression which works well with irradiance due to how blurred the appearance of irradiance is.

 Lys allows you to export the irradiance as a nine coefficient spherical harmonic expansion per channel. Lys allows you to export the irradiance as a nine coefficient spherical harmonic expansion per channel.
