VFB Load images bugs

[Morne]

Hi all

1)
When loading a VRIMG file that was saved with lens effects, the VFB goes nuts and the RGB channel results in some nuclear image. All other channels are fine, just the RGB beauty is a mess

2)
Trying with a multichannel EXR doesnt work as it loads only the RGB and Alpha channel and ignores the rest.

The reason I'm loading the images in the VFB, is because I want to adjust the lens effects after the fact, but this seems an impossible task with the VFB

Will fix both of those, but #2 should still work if you want to apply lens effects - load the EXR and enable the lens effects and adjust as needed - you can then save the RGB separately. Obviously it will be one more file to drag along with the original image, but it should be fine.

Best regards,

That doesn't work. As soon as enable lens effects, red labels are added in the lens effects saying "No channel, please re-render"
no matter what mode it is on

Strange, just tried on another vrimg file, and it seems to be working, even with the denoiser. But it's very fussy...

[Morne]

But I kinda need it to work with and EXR, not a VRIMG...

[Morne]

Is there a way to convert a multichannel EXR to a VRIMG file?

That doesn't work. As soon as enable lens effects, red labels are added in the lens effects saying "No channel, please re-render"

This will happen if color mapping is different from default in the current renderer settings (i.e. burn is different from 1.0 etc).

Yep, I'm aware of that... we will need to change some things in the lens effects implementation to make it work seamlessly with the denoiser.

How far from the top on the priority list is this? Lens Effects has been in VRay for years, but half its features aren't working. Will this be removed at some point or will it work one day? Things like this as well as the intensity masks etc...

VRay is great, but there's things like these that hang for years and seem to never get fixed.

As you have guessed, not terribly far up.

Most of them are actually working. There are only a few options that don't.

Will this be removed at some point

No.

or will it work one day? Things like this as well as the intensity masks etc...

Yes.

VRay is great, but there's things like these that hang for years and seem to never get fixed.

It happens, unfortunately, as much as we try to be on top of everything.

OK thanks for the update Vlado. You guys do great work in general. For now I'll see what I can do with it as is

Hi V-Ray team

Has the loading of multichannel EXR into the VFB been fixed yet? If not, is there an internal build or something where it works that I could get my hands on?

[yolov]

No, not yet, I'm afraid.

OK thanks Alex. Please keep us posted
