scl wrote:What about the other parameters such as Importance?
scl wrote:Do similar consideration apply when we use HDR maps instead of SunSky?
scl wrote:What about when we combine HDR Maps and SunSky with other discrete area lights?
scl wrote:Also, for area lights, if IES data is used, do the Power and Efficacy parameters need to be adjusted independently from the IES?
scl wrote:Regarding HDR maps, is it correct to say that if I knew the latitude/longitude and time of day for when the HDR was created, I could leave the gain value at 1.0 and not model the SunSky at all? If so, is there any advantage in also modeling the SunSky in addition to such an HDR, where the position of the sun would also be properly placed (and hence, be the same as those for the HDR)?
