Hy Juraj, Apreciate your works, very inspired.
But I have few questions about Corona.
I'm new to Corona as well to 3dsmax (went from a C4D enviroment). Tell me how u make the hdri to be seen from inside. I working on a scene where I use an PG hdri to light the scene, but when I look tru the windows it see burn out, I mean it's ok on the inside lighting, but I want to see the outside too. In vray, I often use a sphere with an hdri material aplied and use an compositing tag to uit to not use his gi and shadows, but that the vray works. tryng to see a tutorial on the web but didn't find anything usefull. And see in your last work that u managed to do what I want. Probably is an dumb question, but better asq before make mistake. and for exterior? it work hdri's to make lighting, or its better cun and sky?
Thanks in advice!
Claudiu
P.S. hdri aplied in the enviroment in the corona settings.
Apologies for my gramatical mistakes language.
It's partly because I tone-map the environment a slightly more than the inside in Photoshop using alpha mask ;- ) But I say, it;s only partly and not done for all pictures. It's something around 1EV more darker in the end, still subtle and containing the burn (which is correct and photorealistic) The reason also why burn is so minimal here because the windows are so large and many, and the interior has only bright materials, making very little difference in luminance levels between indoor and outdoor, it's not possible to have this in space with smaller windows.
It's very specific for this example of architecture, it won't apply globally to all situations.
Vray works the same way, the sphere is very wrong aproach there as well, you can just create two domelight or one domelight, and one override,etc.. but not create lightmaterial on sphere. It's not 1999 :- ) As keymaster would mention, it's much harder to sample.
The most correct way to go around this is in post-production, again, just like in photography.
I use HDRi if I can get the benefits of it, like reflections, environment,etc..so it makes sense to use it almost for all exteriors. There is almost no disandvantage to HDRi, in Corona it seems to sample equally fast compared to Sun. (this is definitely not true for IBL lighting in Vray if it also contributes to GI, domelight is just...weird concept)
