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

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.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.
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!
Hey,
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

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.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.
