I'm trying to find out if there's any more "tricks" or settings I can use to get crisp diagonal lines.  I do a lot of kitchen renderings for clients, and constantly struggle with their feedback that edges are fuzzy.

Here's a great example:  This kitchen was rendered on interior fine, all the cabinet materials and surrounding materials have edge-smoothing set to "ultra" and this image has rendered at a huge 6700 X 3500.  

Despite all that, most of the diagonal edges still aren't crisp.  I'm attaching an image with the most egregious lines circled.  

What else can I do to sharpen these up?

Thanks...as always appreciate the feedback!

I think the problem is actually with the Ultra edge smoothing setting.

The forum is having issues with viewing linked files that we haven't resolved yet. It's always better to use the insert image option because it automatically loads without clicking.

Podium diagonal line issue.jpg Here's the image.  Can you explain about the edge smoothing setting...I thought it was developed exactly for this reason.

You're right, it was.... Jim will correct me if I'm wrong, but I think it's just tricky to provide a one-size-fits-all solution for anti-aliasing in a preset-based rendering workflow. 

Edge smoothing is affected by several parameters, and on top of that it's a resolution-dependent operation.  Rendering very large was a good first step, sometimes that helps. This does feel like a pretty clean render to me, though I definitely see where you have issues.

Something that might be worth trying is a subtle "line overlay" to help define the edges.  Nat Ellis does this, and it can be very effective.

1. Use a white style and do a 2D export from SketchUp.
2. Overlay that on your render in Photoshop or PIE

(I can go into more detail if needed)

And... you may want to exhaust other options first, but if nothing else is working for you, you could try altering the anti-aliasing parameters in the preset editor.... just know that this could easily turn into a time consuming trial-and-error (though once you find settings you like, you'd be able to re-use them in future projects).

This is the preset editor section you'd be concerned with:

And this document describes what each of those values means. Just ctrl+f search for "antialiasing" - http://www.suplugins.com/preset/Podium_V2_preset_parameters_21-02-10.pdf

Justin is right in that the one-size-fits-all approach is sometimes challenging for both us and for customers. The easy answer with scenes like yours is to use the fine preset, but it's slow, and it's not a good solution if you want a higher quality base render.

You could of course create a customised preset which is based on the high preset, but with the fine AA settings. That ought to work perfectly, but you will get a double hit on render time!

I need to look at the per-material AA settings. I've been meaning to do this for a while actually.

The bad news is that it's going to be too late for your current scene.

Best solution for now is to reset all material AA to default (Podium Tools - Reset Materials) and use a line overlay as Justin has suggested.

Wondering if you had made any adjustments to the material AA settings that might be helpful.  Just about to work on another rendering which will have similar issues.

While I agree that the overlay problem solves some of the issues, some clients don't like it...they want the photo-real look for marketing.

Thanks again!

You can use line overlay perfectly successfully in realistic renders. Nat has been doing this for a while now. You just need to make it subtle.
Do a search for natstar in the gallery.
