My first step was to look at our concept art made by Izzy, so that I’d know what shape we wanted the jar to look like.
I started the jar by creating cube. I used the extrude tool twice to create the lip/rim. I beveled the edges as the glass would have sharp edges back then. Next, I hollowed out the model by deleting the top faces then, I duplicated the model and attached the two together to make the thick glass.
I thought that I was done with the jar itself however when I moved onto the cork, I realised that I’d made the lip square shaped instead of a circle. So I started again, making the cube and making a cylinder and scaled it so that it would fit within the top poly with room so I can bevel the edges.
I used a Boolean difference tool which cut a circular hole at the top.
I used the extrude tool to start creating the lip. I duplicated the shape and scaled it down slightly to serve as a way to show thickness in the glass. I added an edge loop to the new cylinder on the outer shape and I extruded the top half. Finally, I combined the 2 shapes together and bridged the top borders together.
To create the liquid inside, I made a cube that’s the same size as the inside jar shape and I bevelled the edges so that it matched the shape. I also added a quite flat cylinder and put it on top and made sure that it fit inside the lip. Then I just combined the two shapes together.
The cork was easy to make as I just got a cylinder, flattened it, rescaled the bottom inwards and bevelled the edges.
I placed the cork on top of the jar and with that, the model was finished.
My next and final step is to texture the jar. I made a plain, red lambert for the liquid and for the glass, I created a blinn and changed the settings to:
This gave the effect of glass and I applied it to glass part of the jar. Lastly, I had to texture the cork. I did this by UVing the model and saving the UV as a PNG.
Then I took the UV into Photoshop and covered the cork parts with an image of cork material that I found on textures.com.
I made the texture map into a normal map and specular map using a normal map generator online so that the model had the cork-like roughness and was shiny in the right places.
With the textures done, I applied them all to the model with this end result:
