Plugins needed for this tutorial:
Shape 3D by MKT visit plupin page http://paintdotnet.f...php?f=16&t=5271
1-Start with new image 800x800.
2-Fill it with Black.
3-Add new layer name it interior fill it with transparent white 40.
4-Duplicate Interior layer and name the new layer exterior.
You will have something like this:

5-Add new layer, name it liquid and fill about 3/4 of this layer, or any level you want with the color you like, this will be the level of the liquid in the glass ( I used orange color to fill about 3/4 of the liquid layer)
To get something like this:

6-Add new layer on top off all layers, name it highlight, and draw random vertical white rectangles from top edge to the bottom using Rectangle tool from Tools window, like this:

7-Fade up the top and bottom edges of the white rectangles created in the highlight layer, to do that use Linear Gradient :LinearGradient: with with Transparency Mode :AlphaChannel: :AlphaChannel: , as shown with details in the image below

8-Turn off liquid layer temporary and select interior layer and apply the Shape 3D plugin on it with values and effects shown with 11 red arrows(you can change the values as your desire but keep the Cylinder mode and un-check the Top box and check the Bottom box in All Faces)

Hint:
-Keep the values you made unchanged in Shape 3D plugin cause we will use them same almost in all other layers.
-For better clean edges use higher Anti Alias value but that will slower the rendering, so make last checked box the Anti Alias box when you are satisfied with your shape and wait for the final render.
you should get something like this:

9-Apply Shape 3D plugin on liquid layer using exactly same values and effects.
Hint: If you want transparent juice effect then put liquid layer under interior layer, if no then put it on top of interior layer.( I chose transparent)

10-Select exterior layer, apply the Shape 3D and change only the values shown below:

Move exterior layer down(behind all but not the black background layer)
11-Duplicate highlight layer and name the new layer back highlight and move it behind liquid layer.
12-Select highlight layer (this layer is already on top of all layers, if not then move it on top )and apply Shape 3D with same values as exterior layer changing only the Textural Map from Half Cylinder Map(Repeat) to Half Cylinder Map and better to un-check the Light box, as shown below:

13-Select back highlight layer and apply the Shape 3D again with values of highlight layer changing only the Axis-1=345 and Axis-2=180 in the Object Rotation as shown below:

14-Add new layer on top of liquid layer and draw an orange ellipse using Ellipse
Hint: select the ellipse shape with Rectangle Select tool and move or re-shape it with Move Selected

15-Add new layer on top of all layers and draw a white ellipse on the top edge of the glass using this time Shape Outline mode for Ellipse tool, use the last hint to fit the ellipse:

16-Add some gradient to the last ellipse using Gradient tool with Linear(Reflected)

17-Select interior layer and add Linear Transparency Mode gradient effect on it starting from the bottom of the glass up to the edge of the liquid:

18-Merge interior layer with liquid layer, open Rotate / Zoom effect (find it in Layers > Rotate/Zoom) and add some more 3D effect to the liquid layer (the last resulted layer from merging) put these values or use your own ones but make sure to align the shape using Pan and Zoom options, something like this:

19-Merge all layers down except the black background and repeat Rotate / Zoom effect with same values.
20-Use the Bulge :Bulge: effect find it in Effect > Distort > Bulge to add some curvature to the right and left sides of the glass as shown below:
-For the right side:

-And for the left side just slide the "x" value from 1 to -1:

It looks like the glass is wide so lets change the width of the image from 800 to 750 or less, yes looks much better, and lets add a good background, some reflection and a frame to get the final result as this:

I hope that you enjoyed the tutorial
