Can we have envelope options for anamorphic distortion for lens flares?

What for? I know that lens flares may be abused in a million of ways to achieve certain effects, but I think untying them from the underlying physical calculations by adding envelopes for every parameter somewhat defeats their purpose. I think such things are really better done in an compositing app and your request implies exactly such a use. Anyway, unless LW's lens flares get some more quality (they look washed out most of the time and the secondaries give in no way the impression of "real" flares), it's pointless to have envelopes for parameters.

Agree with Mylenium ;)

To add my 2 cents :

We need lens flares that refract behind transparent surfaces
:(

Don't know that you REALLY want a flare to refract. Usually the effect people DO want to reflect would normally be a volumetric-like effect. How about rendering that refracting?

Lens frares are phenomena due to the lens assembly and they dont exist in any form either 2d, 3d or volumetric.

If you have a mirror in your camera shot, lens flare will never be visible in the mirror. (Sun flare is due to over-brightness)

If you have a translucent flag and the sun behind it, with lens flares to simulate the Sun Brightness, and you want the flag to refract the flare, it doesnt work cause LW cant refract the lens flare.

doesnt work with lens flare cause they cannot displaced according to the FishEye lens, simply because LW lens flare dont refract.
