lens effects like corona?

[kosso_olli]

I lost a lot of sleep before I realized that the Vray Lens effects were render size dependent. I had them looking perfectly on my test render settings, but they always looked minimized on my final render and I couldn't figure out why.

Yeah, at this point the lens effects pretty much become useless for me in resolutions above 8k. I can not wait 2 minutes for the lens effects calculation in full res to be called interactive, and obviously I can not trust the lens effects in the faster, but low res version because of the dependency
And high res is what I do all day long...

They often skip small areas, highlights that are just few pixels large. LensFX do not have any option to blur glare streaks. LensFX glare size does not scale with the intensity of the light source.

I have tried to make my lights from a building at night to highlight, but the highlights where so tiny...

I'm grateful that the lens effects are there, but I'm not very good at them. A bit of hand holding wouldn't damage my pride. Thanks for entertaining the idea, Vlado.

+1 on the subject. As im using octane a lot too, i can say that this is the expected behavior of "realtime" lens effects. I guess new VFB when out, will receive some more love on the subject as a lot of users have been asking this type of stuff.

despite my love for V-Ray I have to confess that V-Ray lens effect is almost useless for me too just because it is really hard, time-consuming to get a realistic result out of it (if you can which is not always possible). I am using ArionFX for glare and bloom quite some time now (from the day it born actually) and recently test corona image editor and it was quite good too but I will stick with ArionFX for the moment,

Really hope V-Ray 4 has a great surprise for us in VFB and LensEffects.

I've invested a lot of time getting to learn the ins and outs of vray's lens effects. They are not very intuitive, a pain in the arse really, but you can get good results.

[mgibeault]

I'm actually curious to do some tests with a real camera and perhaps try to configure the default values for bloom/glare to match that... perhaps it will be useful as a starting point. We'll look into it.

Best regards,

You may want to talk with a lens fanatic to see what kind of lens "defects" are more desirable or what are the main categories of lens types. A Tessar design will tend to show a certain type of defect compared to a Planar design, etc.
Maybe Roger Cicala (https://www.lensrentals.com/blog/author/roger/) or Mike Johnston (http://theonlinephotographer.typepad...log_index.html) would be willing to give some insights?

Like everyone here I too would welcome some refinements/improvements to the lens effects... everything mentioned here as well as a render element that can be easily composited in photoshop by changing blend modes would be ideal...
the inclusion of some sort of chromatic aberration would be brilliant as well, similar to what can be achieved in ArionFX...?

You can already simulate something similar by plugging an appropriate texture into the aperture map slot of the PhysCam. It is not as easy to control, though. And because it needs true depth of field, it will render slightly slower.

chromatic aberration without dof:

Nice, how did you manage that?

[piotrus3333]

hehe,
version with nice colored noise or few times faster one with just the fringing but fully controllable colors?

[tue_nguyen]

I can't use vray lens effects. It's not good result and similar rendering again for bloom or glare. But it's not good. I only see glare effect with same example from other videos: a lighting in dark enviroment. Can't see other good result len flare with other scene. Hope we can improve it.

I agree. I would like a simple solution for adding small glares on all hotspots.

like these?

can't be easier than that.
better ones can be produced with "filter generator tool" included with VRay and just pasted in.

but than again: nothing is wrong with what's already in VRay.
