Re: blackbody and daylight functions


Totally ! ;-)

Our studio is following the same path most studios are : we have an Hosek sky implementation since 2015 (if I recall correctly).
And we are indeed looking at Sebastien Hilaire's work for our next generation Skylight.

Sorry for repeating myself but my question was really about the temperature function for, let's say, an area light.
An artist may think : let's use a kelvin temperature of 20 000 to get a blue sky color on a rim. And because most render engines
rely on black body tables, the blue color will actually look quite purple (to me). Hence my question...

Of course, we would not want a "flat" color on a EnvLight but on an area or spot light to simulate a rim or a top light. A bit like this :

I guess my point is : in many renderer's documentation, you may read that black body temperatures above 15 000 would give you a sky blue color...
When actually it is not really a goof fit imo.

Sorry for the confusion, I don't mean to bother you guys. ;-)
Once again, your answers are much appreciated !
