Ok, kinda big update. I've improved the CoronaCameraMod to include all the basic photographic settings:


The same controls are in render settings, CameraMod overrides them on per-camera basis. You can instance the mod to multiple cameras, even use it with other render plugins cameras.

Next I've added physical units to CoronaLight: candela, lux, lumen, and default ones, which are now interpreted as watts per steradian per square meter. CoronaSun/Sky will remain the way it is, giving physically correct intensity (achieved when its intensity multiplier is set to 1).

All radiance units (standard lights, emission mtl) are assumed to be in watts per steradian per square meter.


PS: clipping values are now taken from the camera

Btw, camera type overrides are not yet supposed to work? Getting Exceptiontime here.

Ondra, can you add please in CoronaCameraMod support for setting white balance?
It's not very comfortable to make it globally in settings, sometimes different settings of WB needs for the same scene , so it's more comfortable to change it via camera :)

You very simply just add camera correction modifier on top of corona camera modifier

Shift would be of use to me. I often have to make renders compatible with renders from other engines, and having functional lens shift is crucial.

The camera correction modifier is not lens shift, though. And it's shit. There's that too. :)

V-Ray's camera has two different methods. They've got the "guess from rotation" method, which is bad and you shouldn't use, and they've got an actual shift as well. The built-in camera corrector only has rotation correction I believe.

If you need it now (no matter if it's going to be implemented or not) you can use a skew or ffd modifier for that specific effect.
Any sufficiently advanced bug is indistinguishable from a feature.

Oh, that's not shift, that is offset. I have honestly never ever used that. On the other hand, i use shift in VrayCamera and Camera Correction modifier on non-Vray cameras quite often. And i bet i am not the only one. Workflows of Modo and 3ds Max community probably differ a bit, and i believe if Modo guys had an one-click solution to make their vertical lines aligned, many of them would not resist the temptation. Even if it may not be technically right solution ;)

Camera correction modifier is not exactly a shift (it change the perspective), and it run just vertically.

Edit: we often need to offset the camera view when we create images for catalogs. In photography, a lot of studios work with this kind of technique and often our client ask us to work in this way. Now, the only way to do it is to have a larger view and render a region, but it means a lot of lost boring time...

I sometimes need to make things compatible with other render engines. The method for "correcting" verticals in 3ds Max actually zooms out! and I haven't been able to accurately reproduce the effect in other software. So if I need to composite my render with something rendered in, say, Maxwell or modo, then I have to have correct film offset.

Also, the lenses I usually work with are real shift lenses, which work like the "offset" setting in V-Ray, not like the "correction" modifier.

Capitain, fully agree.
DeadClown, thanks for your suggest, but as Capitain said, these are corrections that change the perspective, they doesn't work as a real shifted camera.

This test is based on the v.5 June

As this is my first post here...and I have only started using corona today, dare I ask the Noob question of "where do I locate the corona camera mod?" I'm using V5 (latest i believe) Ive tried creating a new camera but I still only have the standard/vray options. In saying this, i'm really happy with the results after such a little time using the software. Converted a mental ray scene lighting only with a hdri and the env slot.

To the developers of this......AMAZING WORK!!!!

Thanks for the replies...II should probably clarify a bit better. I have the CoronaCameraMod in my modifiers but it only shows clipping plane adjustability, not photographic exposure control. I have the latest build of Corona installed.

Thanks

meaning Alpha v5? You will have to wait for alpha v6, or get the daily builds to see it, this is recent feature.

I know it can be added in post, but I'd really like to see vignetting added.

Also, I use some degree of horizontal and/or vertical shift on almost every shot, so adding shift would be great (I know you can use the skew modifier but I'd prefer it in the coronacamera

re: exposure, I quite like right now that the DOF is not linked to exposure.. in vray its a PITA when you want to re:expose but keep the f stop the same (or if you want the exposure the same but alter DOF effect)

I am not sure if you have access to daily builds, but there, f/stop is decoupled from exposure as long as you use Exposure value, and if you use physical camera with ISO, then all the values are linked, so you can simply decide if you want to work with real camera, or work with DoF independent of exposure ;)

I am a licensed user of Arion and Octane. I thought, at that moment, Gpu rendering would be the future of archviz. But when i tested corona, i saw that there was still hope for Cpu rendering. I also feel cheated by gpu rendering solutions cause they are saying that they are very very fast against  cpu solutions. For example arion seems to not release a major upgrade for its maxlive plugin 14 months after its initial release.( I guess they are waiting for  christmas holiday) Both arion and octanes 3dsmax interactivity and integration level are nothing compared to Corona. Your software is the major opponent of V-ray and i think will be when it will become commercial. And it is hard to believe that it is coded by one single man. When i think of this i feel more cheated by gpu solutions cause when they  integrate features to their software ,they act like it is a blessing from heavens. Thanks to the programmer of this succesful software. You have made us open our eyes.
