Hello. I'm doing a simple walk-through animation and have a tiling texture applied to the floor. There is aliasing/noise on the floor texture the furthest from the camera (towards the horizon line).

How to prevent this aliasing?

Global render settings:
Minimum Anti-aliasing: 1
Maximum Anti-aliasing: 8
Threshold: 0.950
Jitter: On

Texture settings:
Quadratic filtering

I can't remember how close the old PA renderer was to the more "recent" scanline and raytracer renderers that came with Maya and Softimage like Mental Ray... but the threshold value is pretty "high" @ 0.950

What I mean by high is that the higher that number the LESS scrutiny it will have comparing against the Min vs Max anti-aliasing sampling. 

So usually for better aliasing you will need the threshold to be lower. 
Mental Ray had a base AA starting point for high quality at 0.100
and in more modern renderers you have Vray doing an easy .010 with Triangle filter for very clean renders without becoming too sharp like Lanzos does.

I'd try to run the renderer at like 0.500 and then 0.100 to see if the render times balloon much between the settings.
But I would imagine that somewhere between .5 and .1 you'll see some pretty clean aliasing. 

I have my Octane running again but I have yet to make new vids with it, this would be an interesting topic concerning PA.
