Unfortunately, there is no 'enough' to prevent bleed-through. It totally
depends on the scale any model is rendered at. At typical scale, 2LDU is
really needed to prevent bleed-through from most angles. Which is a bit
thick for most stickers. :)
But I think 1LDU (approx. .4mm) is a good/realistic value to use for
paper-thin objects like stickers.
One thing that *will* help bleed-through (at least, bleed-through of the
backside of the sticker) is to use BFC coding on sticker parts.

| I don't know if this has been brought up before or not, but if the stickers are separate parts, they will "float" above the piece if you use L3P, L3Lab, or LDView and have seams turned on. Since I would expect most L3P renderings to be done with (...) (23 years ago, 16-Jan-02, to lugnet.cad.dev)
