Hi Bittles
Here's my cheat way to do it. The capsule shape is drawn in Amapi, but with quite a high wire count (based on a circle with 40 points, I think). The screw thread on a wine bottle is quite basic - only one or two turns. Then in Carrara I made a new shading domain in the flat bit of the barrel. The vertical crimps and the dents were drawn as a flat graphic in AI, blurred a bit and then made into a NEW basic layer as a bump map. The dents are OK, but I should have made the vertical crimps a bit less blurred, because they are too roundy and soft here.
The whole object was smoothed to level 1 in Carrara with UV smoothing turned on too. It's not fantastic, but it's fine as a presentation to a client. The graphic was put on in the same way as another shading domain on the lower part of the barrel.
Hope that helps a bit!
