I am rendering an interior. I appear to have a sampling problem as you can see from the image. The min sampling on this was 64 and the max was 256. But I still have jagged edges.

I don’t want to go any higher, actually I would like to go lower because I need this to be part of an animation and the render time are extremely long as it is.

Is there something I can do about this?

Other info
Rendered size = 30507 x 2480 (A4 Size)
FG Preset - High

Thanks

My question is maybe stupid but when I see your output rendering size (30507 x 2480) .. is edge aliasing not only due to image down-scaling when you are displaying it in your image viewer or in max VBE ? Is it still the case when you display it at 100% scale ?

To reduce your rendering time, you could also try to decrease FG settings, sometimes high FG settings does not really give better results but additional rendering time for sure. Just do some tries.

Sorry not to help you more.

I agree that this may be due to downsampling by your viewer.  If you open the full sized image and zoom in, does it still look badly aliased?

If so, what are your Spatial Contrast settings?  These values work along with the Image Precision to reduce jagged edges, and if they are not set correctly even really high Antialiasing settings won’t work.  Default for Spatial Contrast is 0.05, and I’ve seen recommendations for 0.2, 0.4, 0.6 for the RGB values respectively.

Also, I will reiterate that using the High preset for Final Gather is generally more than you’ll need.  We actually get by with the Low preset for most of our renders.  And we also never go over 1 - 16 for the Image Precision.  If you are creating an animation of this space, use 1 - 16 and set your filter to Gauss.  It gives a little softer edge and makes for a smooth movement in animations.

I agree with the above, view at 100%. you can adjust Spatial Contrast and play with different filter settings.
With regard to render times for the animation. Does the resolution need to be so high for that? What medium is it to be broadcast/distributed on?

Thanks again for your feedback. The Spatial Contrast at .4 solved the problem.

I am doing it at that resolution because the client wants to print it A4. The animation I’ll do at 720 x 576. The animation will be delivered on CD.

Normally I never set my sampling more then 1/16. In this case I kept rising it to see if it would solve the problem. I also never normally set FG higher then medium but this time I used the high preset to compensate for not using Sky Portals. Because the Sky Portals were adding to much time to the rendering.
