Introduction |
|
The Decaller tool
is fun and easy to use. Here, we'll use a beer bottle as our
model, and use this great tool to add a label to the bottles
surface.
This tutorial
requires:
Pixels3D
| studio | v3.7 and above
Photoshop
2
bottles of the finest bottled ale you can buy!
|
The
Shaders |
|
Since this is mostly
about one tool I'll be skipping steps in creating our bottle
and focus on the decaller tool and how its used. First, pull
a bottle out of the refrigerator and sample it. Make sure its
the right beer we want to model. Then download the shaders and
launch Pixels3D while we drink our ale.
|
|
Modeling |
|
After downloading
the shader and finishing our first bottle, get another bottle
to sample while we model the ale we just finished. Select Shape>Spline
( B-Spline ) and in the Front Window Pane, start modeling the
side and shape of the empty bottle. Start with the inside and
work your way around to to the outside and back to the center
until you have something similar to the image on the right.
Next select Shape>Lathe,
click OK , and Reshape>Subdivide by 2u/2v.
Feel free to use more subdivisions for better control. Open
Object Info ( cmd-i ) and hide the original spline. We'll reuse
the spline later for liquids.
Open the Shader
Manager ( cmd-w ) and load our Beer_Bottle_Brown
or Green as the shader.

Bump
Map |
|
Now that we have
modeled our bottle, add some bump and then finaly our label
to the surface of the bottle.
Save the model and
Launch Photoshop. Create a B&W image (it doesn't have to
be large) with
a black background colour. Create some white text as shown on
the right. Save as an 8-bit grayscale PICT image.

The
Decaler Tool |
|
Reopen our Bottle
file in Pixels and select the Lathe object ( the bottle
). Choose Utilities>Decaller and, with the lathe still
selected, in
the Camera View Pane, click and drag on the object. You should
see a red box forming around the surface of the object. Once
the red guide is aligned to your liking, (picture top-right
) for our bump, release the mouse button. You will be prompted
with a dialog, pictured right.
Here we can set an
image's location on the surface, since this is for our bump
map, select bump from the pop-up menu and click OK. This will
add an Image Map node to our bump input automatically and scale
it. We may need to rescale the image to fit it nicely on the
lathe.
The nicest
thing about this tool is, it can be repeated as many times as
you like. You can literally stack images upon images.

Quick
Render |
|
If we were to render
it, we would see something like pictured right. I used plain
white shader for a better representation of the surface.
|
|
Repeating
Decaler for Label |
|
Repeat the steps
above, only this time, for the label, select the Diffuse Color
input instead of Bump. This will add the image to the existing
shader. The label image should be located right about here:

Render |
|
After a little tweaking
of the image map in the Diffuse node, the label should fit perfectly
around the bottles shape.
Here is the bottle
I chose, Liefmans Oud Bruin, enjoy and drink up!
