problem reflection

[zacrout]

hi guys , i have a problém with rendering in corona, the relection is not blurred when i use depth of field ,

I think you're wrong - they are blurry.

I also think they are.

You have to take into account the distance through the reflection, and not only the distance to the reflective surface.

Reflections aren't sticked on objects, but at the distance from camera to the reflective surface + surface to the reflected object.

Change the focus of camera several times (far/closer) and check another time.

imho it's edge reflection and it's blurred

thank you guys for your answers, I think you did not detect the problem exactly, I made a comparison between corona and vray and the result is clear, both reflections of lights should be circled in red blur as the focal the camera is fixed on the second sphere, the first sphere is totally blurred because of the depth of field, reflections that exist on the first sphere should be blurred when there 'is one that is not.

Even with scanline render reflections are blurred :-)

The reflections are just super bright, adjust the brightness of the light, render again (or simply change the exposure) and it will look a bit more "round". What you see here is perfectly fine. It's just too bright, that's why it looks like there is no falloff in intensity (thus sharp).

the brithness and multiplier of other lights are the same , i don't understand why the others lights ares reflected correctly ?????

[zacrout]

i adjust the brightness, it's the same result :-(

1, your V-Ray render seems far more blurry.
2, it's too noisy, increasing the blurry feeling

I think that if you correctly match the blurriness and you wait enough time to get rid of noise in V-Ray (maybe 3 weeks...),
you will be better able to make the comparison.

Zacrout, I think you will find the answer to your "problem" here:

It's a common mistake. :)
