Grid Anti-aliasing Issues
Greetings demiurgic bovines,
I’m using a combination of the Grid and Motion Tile effects to create a 3D mesh floor. I’m finding some nasty aliasing occuring as the grid stretches out towards the horizons. I’ve tried a few things to avoid it, including feathering the grid, using the depth of field option on the 3D Camera and trying a sort of psuedo over-sampling thing by precomping everything at twice the resolution. No dice, still getting yucky blocks and steps.
Is there a better way to achieve this effect, other than the obvious “use a 3D program”?
Cheers,
Tristan -

When I want to make a big grid, I use a shape layer with a rectangle and two instances of the Repeater operation.

what resolution are you working at and are you field rendering the output. Both have an impact on whether something “jitters” It also has a lot to do with what type of monitor and compression you may be viewing your output at. Way to many variables to say for sure which to try first.

I’m working at PAL 16:9 Square pixels, but I rebuilt it at HD 1080 to see if it made a difference. It didn’t.
The final output is progressive, so no field issues, but regardless, the issue appears in the project prior to rendering. I’m looking at an Apple iMac LCD monitor but I doubt it’s a screen issue – it seems to be specific to this AE project.
Technically speaking, I wouldn’t say it’s “jittery” – the motion is smooth, it’s just creating those weird curved bands you get when fine patterns aren’t aliasing properly.
