Annoying Reoccurring After Effects Issue
I have frequently encounted the following problem and never really found a solution.
A have a large [10,000 pixels wide, grayscale] ground layer in AE 3d space. The end closer to the horizon has some alias type flickering whenever the camera moves that I can’t seem to get rid of. I have a camera with a shallow depth of field so the horizon is softened, the comp is 1024×576 and set to Advanced 3d.
It seems AE doesn’t like large images like this in 3D space and gets into trouble with shallow perspectives. I’ve also had it with AI files in AE. Anyone encountered this before?
Any suggestions would be greatly appreciated.

If planes sit in the EXACT same space in 3d in AE, we get a flickering problem. Shift it a few pixels.
Try to reduce the size also…maybe reduce it to 25% of its size then up the scale in AE….it depends on how much detail you need though… -
There’s nothing actually intersecting or on the same 3d space. Just a massive floor plate which I have some blue screen actors walking about on in 3D space. It looks a bit like heat haze, which could work in with the theme but it only flickers when the camera moves. I do actually need the detail in the foreground as the ground plate has a texture on it.
Any other ideas? Seems like it’s just a limit of AE6.5. I wonder if this happens in 7.

I’ve run into this once before. I think I just added a small blur to the floor plate and it helped some. You can probably just blur out the far portion of the image, where it meets the horizon, so you do lose detail in the foreground. I’d do the blur in Photoshop, so AE doesn’t have to render it. Don’t know if it’ll work for sure, but worth a shot.

Thanks joefeng. Makes sense. Will give it a go.
