Anti aliassing trick forgotten

Hi all,

I know it is possible to deselect an object (or a e.g. terrain) from anti-aliassing. However, I forgot how to do that and cannot find it again. I guess Horo can help me, but others may provide the answer as well.

Thanks in advance!

    Hansmar - On my website under Raytracing > Bryce Tips > Rendering you find the answer right on top of the page: Disable Anti-Aliasing for Selected Objects. Here is the link https://horo.ch/raytracing/tips/render_en.html  ; Note that there is still AA-rendering running over all objects, even the one disabled from AAing but there will be no AAing on that object.

    Horo, thanks for your reply. Does this trick also work for terrains? I tried it, but cannot see a difference with AA disabled. Maybe I should try it with a new file, because maybe I already changed too much for the trick to work?

    All, I remade the military vehicle and soldier render without retexturing or deleting unseen elements, after making Bryce large address aware again (which I should have done many months ago!). I only retextured the glass textures and added some lights.

    I had a nice 'gravel-like' look on the foreground terrain without AA, which largely disappeared due to AA. I now faked it somehow by adding a displacement map with a high frequency (>3000) and a low strength (3) in the fourth column of the texture. It is not as 'gravely' as I would have liked it, but it looks more like very grey sand and that is not bad either. You can see the more regular look at the foot of the mountains, that have the same texture without displacement. I tried different settings, but the one in the picture I liked best. As you can see, the terrain and positioning of the vehicle and the soldier are not the same is in the earlier version (neither is the sky). Also, the clothing and gun in this version are different. I wonder which version you prefer.

    Hansmar - I used no-AA for grass I made with a terrain using Spikes for the blades. The difference can be seen in the render with and without AAing. Bump is usually smoothed with AAing but not without AAing. It is not always obvious, and the render time does not change much, or at all, because there are usually also other objects in the scene.
    And yes, I like this result, I find it better.
