hi. . . I have a question, where should I put my hdri? or how can i get hdri + corona sun combination?
thank you very much..
simplest solution is to put it in 3dsmax environment (8 key). You can freely combine it with CoronaSun just by creating coronasun object
But if you don’t align them correctly, you will probably get two suns.
ohh ok ok thank you very much , i will try … corona render is so amazing and so real congrats !!! 
I am using a vrayHDRI map it gives you more options and it works fine with corona. I would prefer a coronaHDRI though…
Drag and drop your hdri from env to mat editor, and set it to spherical environment btw.
ok ok thank you very much guys i will tri
While I always used just single HDRi, I recently had job that just looked shitty no matter what with single “sun” (directional shadows from HDRi). So I added CoronSun at 90’ angle difference. Then I had two suns, front and side lightning at the same time :- ) I had to say it looked great and definitely wasn’t noticeable by eye because of varying intensity and blurriness of shadows. It made for cool interior “studio” like setup. Sometimes, reality just sucks.
“Hey guys, let’s photograph this chair in a dual solar system!”
This is why you have rendering software. 
Pretty interesting idea for a photo: photograph something in the morning and next in the evening when sun is facing opposite direction, then blend images together. What a wonderful offtop!
