Hi Guys,

Was wondering if you could give me some ideas on modelling the coffee jar above.
(I know the jars in other countries are different shapes)

Anyhow, I don’t know if you remember but I worked on a completely round jar a while back and I got lots of great advice but I’m really stuck on this one.

The problem is this jar is made up primarily of four sides, but I need the glass to have thickness and I will also be creating a similar shape for the coffee grains to fill it.

I’ve tried the lathe tool in C4d but selecting only four sides leaves me with corners too sharp. My only other option seems to be lofting cross-sections of the ‘glass-thickness’
Through the shape, this seems really teadious, and I know from the last coffee jar I made, that when I add a glass material to this there will be loads of ‘distortions’

Any ideas on where to start?

Thanks in advance,

Tony

u tried loft? also you could try the 4 sided lathe, but then extruding or weighting the edges and then hypernurbing it...

I would do it via hypernurbs

loft would likely be best, but HN shouldn't be too hard either, make it single thick, then make editable and use the make thicker plugin

i would go for a cube that you cut in order to get the rounded edges. maybe the attached pic will give you an idea. sorry for the poor quality...

Thanks Guys,

Looks like hyper nurbs would be the way to go.
I've attached an image of my previous 'coffee jar' that come out really well.

My only concern would be;

if I use hyper nurbs, ie; edit a basic cube to get the shape from the four sided base to a nice round neck (Like the JD / Milk tutorial) will I be able to replicate the glass thickness like in the image attached? I need this because I need to place another object within the glass to attach the coffee-grain material to.

What do you think?

Tony.

hmmm, not sure if i get your concern correctly.

when i builded the milkbottle, i modelled the outside of the bottle, then copied the object and scaled it a bit smaller to get the inside wall of the bottle and combined both of these objects. for the milk inside, i just dublicated the inside of the bottle again, scaled it 0,05 units smaller in the x and z direction and moved it 0,05 units up on the z-axis and cut the upper part a bit shorter and closed it with polygons. i think, you can do this the same way in order to place the coffee-grain-material. hope it helps... :rolleyes:

Thanks Cosmic Bear!

Will give it a try.
