Hello, as title suggest I m new to 3d modelling and I downloaded Corona render trial after hearing positive stuff about it. So far I have setup simple studio scene with corona lights used following tutorial  and everything turned great. Problems arise when I started using Corona Sun and Sky. I always get almost pure white screen in interactive screen and changing values hardly does anything to fix it. Tested on most basic scene with simple plane and teapot. I add corona sun and boom, there goes white bomb. Adding corona sky in enivornment map only makes scene even more white.

EDIT:I fixed it, go to render setup and then under scene tab, change scene environment from 3ds max settings to single map

Even though I fixed it, it would be cool if someone can explain why didn t corona play well with default settings from max and needed change to single map  or lightmix

Because by default, Corona's exposure is set for an interior scene (and if the sun and sky is not seen through a window, limiting the light coming into the scene, it will be overexposed as without walls etc. you have an exterior scene, which needs a different exposure). Simply adjust the Exposure in the VFB.

Hi. The white render with Corona Syn & Sky is overexposed. So turn down the EV value to something around -4,5 and all should work fine.

Hope it helps

Edit: Just as Tom explained :)
