Golden Beer Caps - produced with Blender 2.71 in Cycles
by Fekete Eduard
They are rounded a bit at top (but maybe not enough), but it is not so visible from that angle and because of the lighting at the edges.
I also counted 21 pongs, but i thought that no one would care about the amount. I have to admit that i created it by hand without array modifier so its not that perfect, maybe i shouldn't upload it. Thx for you Feedback UP3D :)
thx, but im sorry to say that the green bottle of beer and the background is not included in the scene, but maybe i upload the whole scene if all is perfect.
Usually bottle caps have 21 prongs and they are a little bit rounded on the top. The edges of the segments also do not look nice.. But I know, it`s not easy to do make them correctly.
