Camera Correction

[FlorianW.]

Why is it not possible to add a 3dsMax Camera Correction Modifier to a Corona CAM?

[TomG]

As far as I know (since the modifier doesn't show up for any camera for me any more in 2018), what it does (correct vertical lines converging) is done by the Tilt / Shift inbuilt to the Corona Camera (and the Max Physical Camera). The Automatic vertical tilt will keep vertical lines vertical. If the Max modifier did something else or something extra, let me know :)

I can apply it just fine (from the top modifiers menu > cameras > camera correction), but it does not seem to work fine (one a wrong axis?).
Anyway, like Tom said, I don't see any use for this combo.

Yeah it's super weird, here the Cameras section is entirely gone in my Modifier list, even for the Legacy cameras that the Camera Correction was intended for (as the newer Max cameras have the built in tilt / shift so didn't need it anyway). Not sure if that's my installation, or if it was actually removed, but I don't see it for any type of Camera :) Won't miss it though as I don't think it does anything any more!

@Tom, are you checking here?
This modifier was never visible on the list in command panel.
Only in the top menu and under right-click menu for cameras.

Shows how often I used it (that is, never lol). Does confirm for me that the perspective correction is all it does!

Still needed for SU imports, rather than creating new cameras in max2017.

For that use, it would still work - only time it doesn't seem to work is applying it to Corona Cams, but it's not needed there as the perspective correction can be done in the Corona Cam itself. Good to know when people might turn to it though :)
