Hi. I tried to use in the corona I liked it. ![Vertuta.jpg](https://europe1.discourse-cdn.com/chaosprd/original/3X/b/a/ba91d94dae3c628d489eeb2a963ca7ed21a73997.jpeg) ![Vertuta1.jpg](https://europe1.discourse-cdn.com/chaosprd/original/3X/a/4/a4c9d5f3ea10792d97f4a9cfdb477ae106b9d82d.jpeg) ![Vertuta2.jpg](https://europe1.discourse-cdn.com/chaosprd/original/3X/d/d/dd92301d820bc542666c94a54153b2897e1c3c15.jpeg) ---

Hi guys, I have done one more task with using Corona and this is really a miracle! %) After 40 minutes an image was almost clean with only one problem. I am unable to find the solution for pointed ies corona litght. I have tried to render the invalid areas separately (by dividing into some parts) but event after 1500 passes the noise is still there. I know that in daily builds this problem has been fixed, so I am looking forward to check it in a new alpha release. Thank you guys! This render makes me happy %) ![MAX_c3.jpg](https://europe1.discourse-cdn.com/chaosprd/original/3X/a/7/a76c893fdb798d07e518ca126519a4829a352380.jpeg) ![MAX_c2.jpg](https://europe1.discourse-cdn.com/chaosprd/original/3X/c/e/ce6b67e49ec99bd0f206f1bdb7496e18ae2b6488.jpeg) ![MAX_c1.jpg](https://europe1.discourse-cdn.com/chaosprd/original/3X/0/8/082eee494ba4e3321fceeda49cbbb9dd13c5d756.jpeg) ---

Great light but bit too soft look overall. Might be because of post ? (like abberation, diffusion,etc…?) Would benefit slight sharpening or down-sampling or both ---

Hi guys! In this work, I decided to test hdri. Found her old job a little changed materials and F9 If it will be interesting i can show the old version. I was pleased with the result. Thanks cоronа %) ![absolut_test_.jpg](https://europe1.discourse-cdn.com/chaosprd/original/3X/a/8/a8ca64d6d6a105553af5f6c900d15fbecebc5f12.jpeg) ---

Did you tired the Topaz DeNoise 5 in PS? That’s great noise cleaner and don’t make to “blurry” results… ---

Hmm, if I understand right, HDRI map has it’s own Sun, and when you move HDRI map (mapping-\>\*rotation) the Sun moves too. Although, if you use a different corona Sun and HDRI map in one scene, I am not sure that you can connect them. And in this case you have two suns, one from HDRI map and one from corona. ---

It’s not unusual to use direct light source / sun in addition with hdri map, since most of hdri’s comes without fully captured sun’s intensity (i’m not talking about hdri’s where sun is rising/ setting or is occluded by thick layer of clouds). But i see no point to lock them together. ---

But i see no point to lock them together. I see, maybe I’m wrong. I’d meant you didn’t used the HDRI in environment slot. Just simple used for the background map, and then if you locked the Sun position for the background (HDRI) and rotating the Sun, than rotating the background too… I seen this technic in the Evermotion Arcviz 2, and this is a really good stuff to changeing together the Sun direction and the background map…And than it’s dosn’t matter do you have or not the Sun on the map or maybe cloudy. No chance to make 2 Sun (light) directions…But if you have a cloudy map, than you have fixing the Sun’s setup for the picture… Do you understand me what I tried to writing here? 😃 You know…my selfthought englissshhh… 😁 ---

Yes, i think i understood, but i still don’t see a point to have that funcionality inside corona. That could be easily made in script, though.
