Transparent stickers


Transparent stickers
#1
It has lately become more common with stickers printed on transparent plastic, to be placed on opaque bricks.
Is it correct, and even necessary, to always add a BFC NOCLIP in a transparent sticker, or is it incorrect to have a NOCLIP in a transparent sticker intended for a opaque brick?

We have a recent set of stickers containing a NOCLIP on the PartTracker and I don't know how to review them.

I was actually wondering about transparant stickers too. Exactly those stickers you mentioned as an example. Maybe a bit off-topic, but are they already transparant? I thought they weren't, but when I wanted to make the sticker transparant, I actually did not quite know how to. In the end, I just made them the color I was applying them on (in my case LBG).

Or maybe skip and remove the transparant piece of the sticker altogether and just keep the actual printed part of the sticker. For LDraw there isn't a whole lot of uses for the extra bit of transparent stickersheet right?

Btw, if you are reviewing those stickers; a, b, h and i need to be white inside the ovals instead of that lightgray; that looks much more like the real sticker. And a is missing a triangle it seems  Wink

Correct on the mentioned issues with a,b,h,i, will have a look at that. About transparency, most of the stickers are transparent with the set I have, but maybe there are different versions?
When rendering the parts I usually replace the transparent color with the actual color of the part on which the sticker is applied to.

I didn't mean the real stickers, I meant the LDraw versions. I though they weren't transparant, but Magnus' wording made me doubt that and I thought I maybe just used them wrong.

I wouldn't use noclip if these stickers are to be applied on opaque bricks.

I think there are two ways to think about this. The first way is to make it look like the real thing. To do that, peel the sticker off the sheet and look at the back. Whatever you see there (Pure white over the printed section? The printed pattern in mirror image? Something else?) is what the part should model to match reality. If it's the printed pattern in mirror image, then noclip for the pattern geometry is the way to achieve this. If it's pure white over the printed section, then backwards-facing BFC'd white geometry would be how to achieve this (with frontwards-facing BFC'd pattern geometry). If it's something else, then that would have to be thought about too.

The other way to look at things is to consider how the sticker is going to be used. If you assume the sticker will always be applied to opaque bricks, then frontwards-facing BFC'd pattern geometry is fine, because the user will never see the back of the sticker. The problem here, is, with stickers being present in LDraw, is it right have them only look right if they're applied to opaque bricks? Are the stickers then only considered valid if used in the same way they are used in the official model?

If I read the Sticker spec right the uncoloured transparent top surface on a sticker should use code 16. Not code 47, Trans_Clear.

And a "transparent" sticker intended to be placed on a opaque brick doesn't need to have a BFC NOCLIP.
But, is it incorrect to have a BFC NOCLIP in a sticker not intended for a transparent brick? Should I Hold-vote it?
