Can anyone show your picture ?

Thank you.

Check out this one of mine:

Or this one of mine, not as impressive as Bruno's though. :-)

DOF in Vue is Slow & Grainy.

Bruno, add noise to a vue render...?  Now that's funny, vue already has too much noise in render.

Much easier, faster, better to add DOF in post with almost any program capable.

I would advise googling "vue 7 rip off" before buying.

 For stills, I prefer adding DOF in Photoshop-- as it's much faster.

You may wish to check it this old tutorial I did awhile back...

CobraEye, 

I did Google "vue 7 rip off" and found only 3 references to it. Two comments, similar to yours, on forums of other 3D products. In fact one of the companies is in direct competition with Vue. No surprise.

Interestingly, just like yourself, there is no contact link, or any other sort of validating information for either of the posters. It's almost as if they don't want to be identified.

The other link was actually here on Renderosity where unbelievably someone was actually calling the FREE version of Pioneer a 'rip-off.' Had a good chuckle on that one! 

CobraEye, no one believes you by now, why don't you just quit? From your statement it becomes very clear you have no valid experience with Vue and you have no idea what you're talking about. If you want to talk about something, do yourself a favour and learn about it first or you just sound ridiculous.

DOF in Vue 7 is not grainy and, although is not as fast as adding it in post (obviously!) is not impossibly slow, especially the hybrid 2.5D. My image was rendered in about 8 hours but it also has Global Radiosity, soft shadows and lots and lots of polygons.

Regarding adding DOF in postwork, the results are not as good, IMO, because of the deficient AA in the z-depth image that Vue produces. This is not noticeable for large objects (buildings, etc) but it becomes noticeable with small blades of grass or tree leaves, for example.

So, CobraEye, if you want to talk bad about something, which seems to be the only thing that you're capable of, talk about z-depth image. Vue's z-depth image is still not as good as Bryce's, for example.

Well, the render speaks for itself. Is it grainy? It isn't, which is why I deceided to add some grain in the blurred areas.
Some here obviously never heard of the 2.5 blur that is available in Vue since version 5, and that creates noise free dof and motion blur.

I'm with Chipp on this, I save out the colour picture and the Z-depth image from Vue and then do the DOF in CS3 using Lens Blur, far quicker and good results.

Sometimes though it doesn't work because my distance between objects isn't enough for the effect to work in CS3.

Yes, as long as you don't have trees or grass too near the camera... Try for yourself and see.

This is very easy to fix. Vincebagna had a similar difficulty and I told him one way to do it. Just play with the levels in Photoshop. See this thread above.

Thanks for that Rutra, hadn't thought of playing with the levels [duhh!]

You could also see this on Cornucopia, which is very interesting regarding cameras and DOF.

The rendering of DOF in Vue is slow - but i only see it as something that is included, that it can be used. Sure a DOF effect can be added with just about any good Paint program, doesn't have to be Photoshop.

But if you want full control of the DOF areas and really want to have an exact distance or area to have a sharp or unsharp look, than you let it calculate in Vue - takes long, but the effect will be calculated more realistic - sure most of times, the exact realstic look isn't needed, as the human eye and brain can be tricked easily, to take pretty anything for real (or unreal), as long as it's following simple basic rules ...

If you want to, take a look at my blog site for a little tutorial, how to setup and use the DOF function - and if you want to have a 'non' grainy DOF render in Vue , you should use the Hybrid v.2.5 method (like Bruno and Rutra already mentioned) with about three render passes, instead of the raytracing method.

All that quickly described in my small tutorial ... the effect should be nice smooth and not grainy ...

Thank you for interesting discussions.

I agree with  Arraxxon

But if you want full control of the DOF areas and really want to have an exact distance or area to have a sharp or unsharp look, than you let it calculate in Vue - takes long, but the effect will be calculated more realistic

In some situations, the post work DOF effect may be sufficient. 
But, I am interested in more realistic DOF effect.
Unless it is super slow, I take quality rather than speed.
I used  Poser7 DOF.  It was not bad, and it was not super slow.

 I was expecting what bruno021, and Rutra had shown.
The DOF effect shown by Rutra.
It is sharply focused at an area and gradually blurred in the front and the back.

Rutra, how slow was the rendering with DOF compared to the rendering without DOF ?

I don't know, I never rendered without DOF. The DOF was part of the concept in my mind since the beginning and so it was not an option for me not to have it.
I will start the render without DOF now, just to see what's Vue's forecast. I'll post something soon.

Well I usually do my Depth of field in post, in Photoshop or Paint Shop Pro, using Depth of FIeld Pro plugin by Richard Rosenman, which is really good, and, it can do animations (when saved as indiviual frames, via a batch process) which makes it prefferable for animations and tweaking by hand, to get just what you want.

However, it DOES leave visible edge distortions that I can see. larger renders and thus, finer masks do a better job, but large depth blur still shows it.

I don't have the latets version however, which may do it better? (damn another thing I need ot buy *mutters darkly, sacrifices CobraEye to the dark gods of finance! :lol: )

This one of the pics I've done with Depth of FIeld, but I honestly can't recall if I di dit in post or inside Vue

PS, oh thanks for the link to the DOF tutorial in C3D, I'd missed that!! Relaly good.
But:
 DAMN YE TO THE HAIRY HELLS OF HEDGEHOG-EATING HAGGIS'S BOWELS!!!
Why? Cause it has a link to a cool but madly expensive Photoshop plugin!!

Must resist, Photoshop plugin junky overload!!  :tt2:  :lol:
Chocolate, and plugins...my big weakenesses, sigh, hehe

The prepass was done in about 2 minutes and, after the first 2 rows of render buckets were finished, the forecast was for about 2 hours more. We all know that Vue's render time forecast is not very reliable but assuming it is, seems that DOF (at least in the case of my image) increases the render time in about 4 times. Like I said, it's slow but not impossibly slow. I can perfectly live with an 8 hour render (I typically let Vue render while I'm sleeping or while I'm at work and both take about 8 hours :-)).

Sure - Vue render time forecast can trick you a lot ...

I allways like an estimation of render time for my scenes - just to see, how long my PC has to render in full speed with my 4 cores, just to see, if it still makes sense, to wait for the result or just do something else away from the computer ...

For example  - i want to render a 2000x1250 image, then i first render a really small sized image, with the exact ratio - like here a 320x200 image.
This small image most of times gets rendered really fast.

Then i multiply the rendertime by 36  (about 6x320 for y-size and 6x200 for x-size)  - it gives me a pretty good estimation for the highres render.

Most of times it's pretty close to the really needed time - many times Vue is even faster than my calculated estimation ...

Thank you Rutra,

I can also live with an 8 hour render.
I ordered Vue7 upgrade.

I like DOF (Bokeh) effect.
I did buy DSLR, and expensive lens for the beautiful Bokeh effect in the past.
Bokeh is expensive.
