Am a new user of Vue Esprit 5 and I'm quite disappointed with the quality of the anti-aliasing - see below (worst bits circled in red)

e.g.

Although the above images was not created on highest settings, I've tried different settings - StandardSuperior, and have turned all available parameters to different settings to try to get a smooth edge, but I cannot seem to eliminate a roughness and graininess which seems to be possible even at low quality in other 3D packages.

I've also noticed that anti-aliasing seems rougher when a shadow edge is created by volumetric lighting,

Is this a known issue with Vue, or is there something I can try to improve the quality without having the settings up at max?

Any help appreciated!

Thanks
Richard

I'm having similar problems with Vue5i.

To those who have used Vue for a while, is it generally better for exteriors and lanscapes (where there is so much detail you wouldn't notice the odd rough edge) than for detailed indoorsinterior work where it's more visible?

Thanks

Ok, we need more details, because Vue's AA is alright. What is the size of the render? What kind of atmoshpere are you using? (volumetric/standard)

What lighting model? (standard/ga/gi/gr)

I see a volumetric spotlight, which may be the cause of the artifacts you are seeing. In my eyes, this is not an AA problem, but a volumetric light problem.

Volumetrics tend to be more grainy than non volumetrics ( lights & atmospheres), you need to boost the volumetrcis quality to at least 2. For atmospheres, it's in the fog & haze tab of the atmosphere editor. For lights, right clik the volumetric icon and choose edit volumetric settings, and boost the quality there.

One lore thing: are your walls boleans? If so, there isn't much to do about it, boolean operations always have artifacts, even in the best 3D apps, it's a geometry problem.

As for AA settings, you need around 12 subpixel samples, standard quality.

If you use a preset render quality, don't choose final, not enough, but don't choose ultra either, too long to render, and settings way too high.

Also some should be 'curable', at least as far a booleans if you convert them to polys...just a thought, and that comment from bruno about the Vol Light is right on, when I was playin with the DEMO I found his solution to be the one I came up with as well...also I found setting up using, IIRC, user defined or user setting, and the cranking the AA everywhere I could produced nice, if somewhat slow results.....

Just use Ultra settings.  It takes longer but it's clearly the best setting by far

If you choose to use your own settings though:

1. Make sure tile rendering is off

2. there is a section caleld anti aliasing where you can make sure that anti-aliasing is at a higher quality.  (i wouldn't make it the HIGHEST though because that takes TOO long to redner).

Indeed turn tile off...a handy feature I've yet to understand as I couldn't use it in the demo..but it sounds dangerous...LOL...and take AA up by percents till you have a good [acceptable to you] tradeoff tween Quality and Render Speed...

Thanks folks - that's really helpful. Have got some much better results already without having to use maximum values.

For some reason the "Standard" AA results seem just as good as the Superior ones, in the renders I've tried so far.

Many thanks!
Richard

I wrote a tutorial on setting the render and light options to help get the best render without wasting a lot of time.  Some of the settings apply to Vue 5 Infinite only.  Hope it helps.

Excellent thanks!

Do you know if the Lighttune module for Esprit includes these advanced settings?

Richard

AA: Min 12, Max 64; Quality 49%
Volumetric Quality Boost 4.00

It's on the shadow side of the sphere that it's worst ... any thoughts?

Thanks
Richard

im surprised ur getting results like this.  ive always liked the anti-aliasing engine in Vue.  if u could give me the scene file ill try rendering it on my machine and see what i can do.

I think the problem is related to volumetric lighting, even at highest AA and volumetric light quality settings. I've tried with sun lights and the problems are not nearly so pronounced.

I've found these jagged artefacts in a range of different settings where volumetric light has been used - the worst was the one shown here.

I hope this has improved in Vue 6!

Thanks
Richard

Hi Richard,

Peggy Walters mentioned her great tutorial, please check it out.

Try using a Min 4 Max 8 Quality 100% and see if that doesn't do the trick.

best, Chipp Walters -no relation to Peggy ;-)

I'm taking an educated guesst here based on stuff that happened with Vue 4.  It could be the problem is in the demo but has been fixed in an update to Vue 5.  I don't know if it's the case with Vue 5 but, if my memory serves me, Vue 4's demo was based on an early version of Vue and periodicly certain bugs were reported that had been fixed and each time the reporter was using the demo.  Several update to Vue 5 have improved the AA and lighting models. 

Thanks - I'll check out the bug fix lists to see if anything has been mentioned.

Thanks
Richard

This was a helpful thread and great tutorial!

Yes, this has been a very informative thread.  I'm glad you chose to post your difficulties here.  We can all learn something from this.  Well, as a beginniner, I know I can, lol.

The tip about turning up volumetric light quality is very timely.  I recently rendered an image with a volumetric atmo. but something about it just didn't look right. That must have been it!

Also I would like to add:  I enabled "optimize last render pass" which, and I'm paraphrasing, reduces render times by 3X while leaving out miniscule details.  To me the "miniscule details" it left out were a little too obvious and not really worh the time savings of approximately 3hrs.

One more thing I'd like to add is I never use any AA at all on my final render.  Instead I render at least 4 times larger and then downsample.  It seems to save a bit of time and a lot of guesswork.

I may be wrong about this!!!  Like I said.  I'm a beginner.  Maybe someone can verify this.

Thanks.  :)

Edit:  Sorry, I forgot to mention I'm using Vue5ProStudio.  At least until my Vue5Inf. download link arrives.  WooHoo!!  :D

Another thing to try :

Render in User Setting mode and make sure you increase the maximum nimber of sub rays by clicking on 'Edit'  next to Object Antialiasing. You will find more options to fine tune your AA there.

The problem is "Optimise Volumetric Lights". Turn it off and you get MUCH better results in a scene where there is a bright volumetric light. See attached image for comparison, esp the areas circled.

AA settings: Standard, Min 8, Max 64, Quality 85%
Advanced Effects Quality 75%

Would be interesting to see how this compares with other scenes with volumetric light.

Thanks
Richard
