Subject: Disappointing AA in Vue 7

I tried one of my old Vue 6 scenes in Vue 7 (PLE) to find some pretty bad AA artefacts. It's a GR render (+1.0).

The top render is using the following

Sharp
Min = 8
Max = 16
Quality = 90;

The lower render uses

Sharp
32
64
100%

Which is better, but those settings are way above my usual ranges. I had similar issues in Vue 6 - could anyone shed some light on this? I remember there being discussion about AA + GR.

Thanks
Richard

Lately almost all my images (outdoor or indoor) are rendered in GR and I never noticed any decrease in AA from Vue6. My usual settings when I have plants or clouds are around 10/25/100% and when I don't (like in your image), it's around 8/16/100%. I don't use Sharp, I prefer Crisp.

Could you show us your render settings? Maybe this would help to understand.

 Richard,

Is it possible the line is a function of a texture map (bump or trans channel)? If so, try setting texture filtering to something like 30-50 and see what you get.

best,
Chipp

 Artur,

You probably already know this, but typically serious AA problems show up with straight or geometrically precise lines. Nature scenes can be rendered with much lower AA as they don't such geometries in them. I know you use figures as well, but even they don't have the AA problems which a straight line can create. Richard has a particularly difficult example.

Thanks ... Chipp is right it's an edge issue - classic AA problem!

The edges in question have a pretty plain white-ish material, no textures. Those edges are the skirting boards along the base of the wall, which under low-frequency photon condtions, reveals the weaknesses in the lightingAA interaction.

Yep - it's definitely a "straight edge + lighting" issue. Some of the other edges in the image are beautifully smooth, even those very slightly off the horizontal or vertical are silky smooth, but they are the ones in high-lit areas, whcih suggests it isn't just an AA issue.

I might need to remodel the skirting boards to project further from the wall and to have a larger chamfer and see if that helps.

Thanks
Richard

 Richard,

Try rendering w/out GI/Radiosity using just Global Ambience and see what happens to the edge. My guess it will render fine with the lower settings. Of course it won't look right, but it's a quick test to see if the AA issues have to do with the Radiosity settings. If so, then there are a few settings you can use which might help for small surfaces like that. Let me know and I'll dig around and see what I can find.

I know about the problem with geometric lines. True I don't have many but I do have some. Look at this example: http://www.renderosity.com/mod/gallery/index.php?image_id=1829203

There's several geometric lines, and other very fine and precise ones in the characters and stand. This was rendered in GR. There's a bit of aliasing here and there but not much (and I even sharpened the image a bit in PS, which strengthens some of the alias even further). AA settings are Crisp/10/24/100%.


chippwalters ( ) posted Thu, 19 February 2009 at 8:44 PM

 Artur,
Yes, that's an excellent example! And your settings are not too far off of Richard's either. I believe I use pretty much the same settings as you for this type of scene. I've heard there's a huge render time difference between 95% and 100%, but haven't checked it myself.

Not a lot of difference in GA mode - it must be something to do with the model + the HDRI lighting + AA settings combined.

I tried a different HDRI and the problem is greatly reduced.

I use as high a resolution as I can find for HDR images.

People have been complaining about the grain, noise, and flicker of vue for e-ons!

There is no hope.

People at e-on say vue 7 renders faster than vue 6 (they even use it as a selling point) but the truth is the render settings are lower thus render speed increase.  Truth be told vue 7 renders slower at the same settings than vue 6 at the same quality.

Compositing in AE is the best way around the known vue short-comings.

Hi, I was thinking of getting Vue 7 mainly for the faster render times but I just read this and now I'm not so sure. So What is the truth regarding faster render times in Vue 7? Is it not significantly faster or was that a lot of hype?

Also what id Kronos FX? I can't find any information on it but I heard it makes editing of animation splines a lot easier and other things too. Please shed some light on this if you can?

Thanks

You can ignore everything CobraEye says. He never has a clue of what he's talking about. In a recent post in another thread it became obvious to everyone that he's probably still using Vue 4, as he didn't even know about a feature that was introduced in Vue 5. That tells a lot about the value of his posts.

Vue 7 is faster than Vue 6 for comparable render quality, for most of the environments or situations. Of course, if you compare Vue 7 render time in spectral2 clouds with Vue 6 render time in spectral1 clouds, then Vue 6 is faster because spectral2 clouds are slow to render. For example, one thing where Vue7 is much, much better is in handling displacement. With Vue 7.5, all the CPU cores are used to handle procedural terrains, dynamically populating ecosystems, etc, unlike previous versions. That's a huge step up.

There were a lot of posts by chippwalters and others about render time comparison when Vue7 first came out, do a search and you'll see.

That seems a little harsh IMO but I'll reserve comment as I don't know enough about the situation.

Thanks for that Rutra, I am using Vue mostly for animation so I need the clouds to render "FAST". So are you saying the clouds will render at the same speed in 7 as 6 but they will look a lot better by comparison.

I was under the impression from the Eon/Vue7 website that Vue 7 Spectral clouds rendered a LOT faster but it doesn't seem that is the case.

I have an airplane animation that I am rendering in Vue 6 Infinite but the render times for a 360 x 480 render with spectral clouds is about 20 minutes per frame with "User" render settings so I gave up on it.

I was hoping if I bought Vue 7 it might cut the render times of the same scene in half but it sounds like I might be disappointed if I am expecting something of a 50% improvement in render times in Vue 7.

Does anyone know if the Terragen 2 render times are any better? I really don't think I 'll go to Terragen unless it was significantly faster though as I have a fair amount of change into Vue with all of the plant/models etc.

It would be great if someone could do a comparison test of a spectral cloud scene (where the camera is up in the clouds) in Vue 6 and Vue 7 at 360 x 640 and post the images and the render times.

I am downloading the demo to try it out for myself but if anyone has any further advice or comments on rendering times in Vue 6 vs. Vue 7 please chime in.

Thanks :)

Yes, truth can be harsh.

Quote - "So are you saying the clouds will render at the same speed in 7 as 6 but they will look a lot better by comparison."

I didn't say that. I said that Vue7 has a new type of clouds (spectral2) that look really good but are slower to render than the normal spectral clouds. The render time of Vue7 and Vue6 regarding normal clouds is aproximately the same, there were no big improvements that I could detect in this specific area.

You should not expect improvements in this range, that's too much to hope for in general but especially in clouds. But there's one thing that is new in Vue7 and that is important for animations: the calculation of indirect lighting can be made once and then reutilized in the following frames. As I read (because I never do animations), that saves a lot of time but, of course, it'll also depend on the subject being rendered (I don't know if that's very relevant for your specific scene). No doubt, the best is for you to try it out for yourself.

 Thanks Rutra. I am downloading the demo to give it a try and I will check out that indirect lighting.
