Another hint :D When you start the IR  Click on tools button to remove the tools in the right side of the IR and you get some more pixels :D

If you say. This control is the pure magic. Vray just now implemented it like Energy preservation. i hope well see it in corona 9

I mean this when somewhere is burning to remove it easier. Thanks in advance!

Reinhard operator. range 1-999 is matching VRay’s 0-1.
Thanks for all answers  but this i think is the most accurate i know every way to coorect the hilight burn but i thought that this parameter in Vray is somethin else if it is thrue that is matchin vray s 0-1 everything is ok.

Please implement burn value like in Vray Thanks!

Here i have made some examples what i mean. Whit Color preserve you acheave natural look with corona you just can desaturate the whole render....  i make the corona sample more desaturated to unerstand me i can achieve similar result but its not the same. Here with color preserve you need just one click.

Howdy! I'll try to explain things in a way that hopefully will make the most sense. I'll generalize a bit too because color spaces are complex :)

The ACES OT operator in Corona takes care of the tone mapping part according to the ACES specs. To put it in layman terms, it'll tone map the image in that filmic ACES style and so the highlights will look more "natural" and the darker parts will get a nice treatment as well. You'll also notice that depending on the intensity of the colors and the exposure you're using that the colors will behave much more like they would if you were taking a photo with your camera. That's what the ACES OT operator does.

The ACES tone mapping part is just one bit of what ACES does as a whole though. Primarily it is used to offer a color space (or a set of) that artists in a production can easily transition in and out of. Without it it's harder to keep everyone on the same page because converting between all the different color spaces that are out there is... Tough. This whole ordeal is not implemented in Corona at the moment. From my understanding that would be the OCIO part mainly.

The ACES color space can also be used for rendering calculations. Some renderers use the somewhat color limited sRGB color space to calculate things under the hood. Other renderers, like Corona, use wider ones. There's pros and cons to each but generally speaking the current trend is that more is better and since ACES offers a really wide gamut of colors it is typically what gets implemented as the color space in which renderers make it calculations these days. As mentioned though, Corona always used a wider color space so it's pretty much ACES like from the start. Are there wider color spaces than ACES? Yep. But ACES is just kind of becoming the one everyone is getting used to working with lately plus its wide enough as is. TLDR though, Corona is using a wider color space by default and while it isn't exactly like ACES it's more similar to ACES than to sRGB. And again, from my understanding there's pros and cons to sRGB and wider stuff.

So the above is again, a bit generalized but hopefully it helps understand things a bit better :)

Oh and dully noted on the tutorial part. We're giving this one a +1. Thank you!

Thank you man! I understand it Coronoa uses wider color range from the start thats why it was looking better than all other engines evrica. I understand that it is near ACES than sRGB wihch is cool but it is not the same right now i noticed that somethink like SDR than HDR . But in this case ACES TO  is just a tonemap not a real ACES  like in Vray with its real calculations unrer the bonet with OCIO. Thank you for the information!

Hello im happy that you you embedded ACES! I have some questions about how it is made and what are the principles of working. Is it just some filmic tonemaping function which handles better with over exposure. Please if it possible give us some tutorial just for ACES. I saw this tutorial for Vray and everything is explained there. First  ACES support more colors and when you turn it on you reach more deeper color both in VRay and Corona BUT after that to work propertly you have to convert basic colors and textures you are using for ACES  after that you reach not more vibrant and saturated colors but the opposite more natural and super realistic colors. In the Corona i dont see that natural look when turn on ACES just more somethin like more darker maby i am wrong i dont know but i think its not doing its thing propertly. Is it everythin automatic for corona for example converting  basic colors and all textures and does physcal materials  support it natively. Please give more information how it works or if it is possible whole video just for it.  Thanks in advance!


I wrote a script because we also had some issues with models from Archicad and Sketchup. Newer Max versions import those models with Physical materials.
The script itself is quite simple and converts materials of selected objects from Physical material to Corona Legacy Material.
This script may help you as well and is free for download on gumroad.

At the moment script supports:
Base color
Diffuse map
Multisub material

Link for download:

It dosent work for me. I am with corona 7 and when convert with your script it says 0 materials was converted why is that?

Excuse my ignorance, but how adding round edges in material would save any RAM, or time for that matter?
Test it with 100 boxes with round edges and 100 chamfer boxes and you will be amaized of the efficiency press 7 to see the stats ot fhe scene to watch tre results.

I meant round edges in material (your request) vs round edges as separate map (current implementation). I didn't know that you are not aware that Corona has round edges for ages.
Oh hahah i understand! :D yes i didnt know it for Corona  i use it in other engines there is emplemented right in the materials.

I found the way how to do it ;D i have 4k monitor and 8k capable gpu and just tweak the resolution. Just go to nvidia settings in Adjust desktop settings check the Override the scaling after that go to change resolution and then from custom set something more than your resolution in HD ratio and test if it will work for you. Have a nice IR rendering :D except  when you have direct ligt in front of the camera. Every other render you will achieve X several times less time for the same render in protudction.

Please put round edges in materials we waste so much ram. Projects will be much faster. Thanks in advance!
