vray lens flares problem

[leo.surrealismo]

hi, I'm having trouble with the lens effects.
If you look on the attached images, you will see that the flare on the kitchen light is cut out. What would be the reason? in small tests, the flare was fine.

thank you

Hi,

Would it be possible to attach part of the scene that reproduces the lens effect issue? Or you can send us the file complete scene to support@chaosgroup.com
Do you use DR ?

If you are using DR, then I suspect its the same issue I flagged up a while ago with DR and lens effects.

I found a workaround for the time being, until it is fixed.
If you activate the Lens Effects in the old "effects" section (in the env & effects dialog)
Set the weight to 0 for both, but turn on the intensity mask to match whatever you have in the VFB lens effects settings. This will then ensure the mask works properly with DR.

No idea why, but it works

Yes, I'm using distributed rendering. uploading right now.

Hi Alex,

I can't find this report in our system, can you point me to the thread or give me the ticket number (if it was reported via our support mail)?

Thanks Alex, now I found it and looks very similar to the problem reported here. Unfortunately we don't have this fixed yet.

Please let us know if the workaround provided by Alex works for you. We can also check the file in order to be sure that we don't miss something here.

file sent, I hope that would help you on finding the solution.

Thank you very much.
It is the same issue, so we will updated the thread as soon as the fix came out.

I'm running into this issue, not with DR but with backburner. - Will try that work around now.

You can actually go the the nodes and open up the lens effects dialogue and see that they are still turned on, but they do not get saved into the image.

I activated the lens effects in the '8' hot key menu effects menu.
But then got stuck ... what or where is the 'weight' that you set to 0? and where is the intensity mask?

I can see the intensity mask option in the vray fb lens effects but not under the 3dsmax one.
Do you mean you set the weight in the vray buffer to zero?

This makes me think your work around is just turning on 3dsmax's lens effects instead of vrays.

Do you have to apply a glow or a ring or some other option to the 3dsmax's options?

Oh, VRAY lens effects I didn't get that far down the list. Cheers!

Interesting it seems that bloom is working over backburner without the work around but not glare.

and it seems that the intensity variable does not work, on this local render i am testing.

"Intensity - when this option is enabled, the glare effect will be applied only around pixels that have a value larger than the number specified in the field to the right."

If I turn intensity on the glare is gone, no matter what number i insert in there... 5000, 500, 50, 1, 5 , 3, .5, .1, .01, 0.00

but unchecking the box and glare is all over the place. perhaps this information will help track down the bug. Does anyone know what the intesity value is supposed to correspond to? I assume it would be the float value of the pixels, I do have some pixels over 1.0,1.0,1.0 brightness.
