3d precomp and effects
i’ve created a 4 sided box out of solids (no top and bottom) and precomped it. i brought the box into my main comp and selected the collapse transformation toggle. i then built a wall out of the boxes – everything worked fine. however, i wanted to animate a tint effect on one of the boxes in the main comp but as soon as i applied the tint to the precomp layer, the box seemed to ‘pop’ out of the 3d wall so that it looked like it was in front of the other boxes. i can’t think of what i need to do to correct this. i’m sure this is a simple thing i’m overlooking but i’m drawing a blank. anyone?

Effects work on flattened (2D) buffers, not 3D layers/ objects. If you apply an effect to a collapsed layer, you force AE to ignore all folded 3D properties and thus it will pop out of place (it is mathematically correctly in the same place, but AE does no longer calculate perspective because it treats it like a flat plane). You only alternatives are to pre-comp again or apply your tint on an adjustment layer.

I’d add a expression control to your pre-comp in the main comp, then put the tint filter on the original layer in the pre-comp. Then tie the property you want to animate to the slider something like this:
comp(“Comp 1”).layer(“PreComp1”).effect(“Color Control”)(“Color”)
for map black for example
and then
comp(“Comp 1”).layer(“PreComp1”).effect(“Slider Control”)(“Slider”)
for Amount to tint.
now you can control the tint effect from the pre-comp and maintain 3D because your tint effect is applied to the layer in the pre-comp
i’m not very good at this but I hope you got it
