I was in the mood to redo my Tabasco bottle. I did the v1 a few weeks ago, it was essentially a memory exercice : I wanted to know how much stuff and tricks I remembered from my last year's brief Blender donut-initiation.

This first version was... simplistic. This was essentially an exercice to get the shapes and proportions right, and so I tried to keep the geometry as close to the original as possible, did some very shy materials work, and this was pretty much it. My focus was elsewhere actually : importing that thing into SL, where I'd apply a texture to give it the labels and such.
I was satisfied.
But many things kept bugging me, and I reloaded my file a few times in order to see if I could fix them. This is when I realized that I made some conceptual errors in my design, and that in order to get the results I wanted, it would be easier to redo it from scratch.
The thing I really wanted was the thickness of the glass, so I could play with refraction. The first version was basically a cylinder, outer surface only. Here I needed the volume to be hollow to have inside & outside surfaces, thus - glass thickness.
The IOR works pretty well, except for the top glassy part where it might be a bit too strong and eat the thickness. The glass node didn't give me lots of playroom here, I suppose I missed something, again, but sooner or later I'll get it right. Maybe I should have used a second material just for this part.
I also did some UV work here, and getting that label right was a fun challenge. Definitely not perfect, I suppose there are some tools or tricks to get a 45° square on a convex surface done, but for inexperienced me, this was again good-enough. Let's just blame the label-printing factory.
Now I don't know how this would behave in SL, I did a very quick upload simulation, and I think the best I could do is 3 LI (whereas the first version was 2 LI). Which isn't bad, considering it has nearly 3x more triangles.
Hmmmmmmmmmmm...
And now that I'm thinking of this... I think I'm gonna do a quick test on that v2, I can probably improve it slightly.
heads to Blender
Eh, nope. No dramatic change. But I'll keep this in mind for the future.
