365 days of SL, day 92:


(Click for larger — 1920x1033 PNG, 2086 KiB)

I bought another pair of boots recently – on Wednesday, in fact –, and the above screenshot shows me wearing them. :)

I'll admit it does look a bit flat, and I'd love to have turned on lights/shadows to help with that, but unfortunately, something about the boots or SL's rendering causes parts of my legs and feet to stick to them when I do that. The effect is reproducable, and it goes away again once I turn off lights/shadows again; I have no idea what is going on there, although I suspect the boots are using invisiprims.

In fact, actually looking at that page now, it seems that these are indeed the culprit:

Invisiprims work by rendering to the depth buffer (but not the color buffer) before avatars but after prims. With deferred rendering, the depth information is used for lighting, so any invisiprim would change the position of prims behind it for lighting (it just looks broken).

And digging deeper and looking at this SL wiki page also makes it abundantly clear that a) lighting and shadows turns on deferred rendering, and that b) "invisaprims [sic] do not work with deferred rendering". Ah well, it's a pity, but at least the boots weren't expensive, and I learned something new.

The store offered a demo so you could try-before-you-buy, too, but it didn't occur to me that lighting/shadow could make a difference; next time, I'll know better. Of course, why people are still selling objects like this unchanged these days is beyond me — doubly so since it's not just me who'll see them broken but also others who may have light/shadows enabled, with me not even realizing that I'm looking "off" to them.

In any case, for "normal" screenshots, the boots are still nice, and perhaps I'll be able to find or make an alpha mask for my legs that'll make the invisiprims unnecessary; that, or I might be able to create a modified shape that'll actually fit me into the boots without the need for any trickeries. :P

Well, just re-enact the scene IRL. ^_^ No invisiprims to worry about there! Although the costs definitely do go up..

It's rather surprising such a design would still be on sale, really - invisis have never worked with deferred lighting, and were mostly obsoleted by alpha layers a year or two back. (Exceptions do exist, of course) Is there maybe an alpha version included as well?

Still, a lovely look regardless. ^_^

*s* I'd love to, but it'd be costly, yes, if it'd work at all. High-heeled boots tend to not come in my size; those that do have the usual "pervert's premium" tacked on to their price.

What's more, narrow heels can pose problems when you're heavy (and since I'm tall, I am). Good heels will have a steel core, but most shoe/boot manufacturers place limits on how much you should weigh, lest the heels may break off. (And those limits are usually below the 90-95 kg I have these days.)

So... yeah, I'd love to, but I don't see it happening, alas.

Anyhow, yeah, it is a bit surprising, isn't it? And no, there are no alpha layers included. The boots themselves appear to have been made in April 2010 (sheesh, I had to enlist a friend's help to find out; Firestorm appears to be entirely unwilling to share that information with you in any way!); definitely not THAT old. Ah well.

Thanks, too. ^^ I'm not sure the boots go so well with these tights and the swimsuit, but then I don't know anything about fashion and clothes and what looks good. x.x
