lens effect problem

V-Ray V-Ray for 3ds Max Issues

Try the lens effects and here is a problem:

When I click on Update effect, vray render picture (for the first time), but results in vray frame buffer is terrible, its some kind of a bug. Render is overexposed and effect is not there.
If I first click on render (F9) and after that click on update effect, it render picture again. Render looks ok then, but it render it twice. Grrrrr. Why is that? Vlado please…

I find out that if I first open Effects tab and then hit F9, its ok and I can check interactive and change values. But if I first hit F9 and then open effects tab and check interactive or change values, vray render picture again and show effect after that. Really annoying. At least it works if effect tab is opened first.

I have a similar problem.
If I want to update the effect then it only updates in MaxFrameBuffer and VrayFrameBuffer is linear like (LensEffectsElement) I work with LWF.

yes i have the same problem, normally i switch to max frame buffer for lens effects setup, then switch back to vfb for rest of work.

Happened to me too. I leave lens effects box open and hit f9 if i dont want to have any problems. Sometimes when i click on interactive, lens effects goes and renders it all again but if i quickly cancel that 2nd render, the lens effects works perfectly. Very strange but its working nonetheless.
