With this tutorial you will learn how to unfold a model that has thickness applied. Also covered in this tutorial are opening and saving the texture map with UV Mapper, brief editing in an art program such as Paint Shop Pro or Photoshop and finally testing the texture map on the model in Poser.


Step 1: Setting Up

Open zip file of the wine bottle model. You may keep the wine bottle model as a gift for taking this tutorial. It is free for both commercial and noncommercial use.

In order to be able to texture our wine bottle we need to cut it up using the Select Edges tool in Hexagon.


Set your select tool on Select Edges(F3). Click on the Universal Manipulator(U).


My object view is set to smoothed solid.


These are your panning, rotation and zoom tools.


Step 2: Selecting Edges

When you apply a thickness to an object the inside of the object will need to be cut as well as the outside. We will be cutting our bottle in half basically.

Let's begin at the bottom of the bottle. Hold the Shift key down so that you can make multiple selections. If you make a mistake and select the wrong edge just click again on the mistaken edge to deselect it using the Ctrl key.


Zoom in close as you near the top of the bottle so you can see all of the edges.


When you get to the top of the bottle rotate as needed and do the same thing on the opposite side as shown;


Step 3: Select Top and Bottom Edges

Keep the Shift key down and select the uppermost edge around the top of the bottle.


When that is done rotate your view so you can see the bottom of the bottle and repeat.


Step 4: Selecting the Inside Edges Top and Bottom

Now comes the tricky part and it may take a bit of practice only because it is easy to select the wrong edges at the top of the bottle. The best way to avoid this is to zoom in close. We will begin with the bottom of the bottle's inner circle. Rotate and zoom in as needed.



Repeat for the top inner edges of the bottle's cork.


Step 5: Selecting Inside Edges

Zoom in close to the bottom of the bottle and select the inside edge of the first seam. Begin from the inner selected edge of the circle and move up along the seams to the top of the bottle as shown in the images. Zoom and rotate as needed to get a better view.



Here is a close-up of how the top and bottom selected edges should look.



Entire Edge Selection;


Step 6: Unfold

Now comes the fun part.

  1. 1.Click on the UV and Paint tab and then click on the Unfold tool which is in the shape of a head.

2.Click on the plus sign to add your edge selections to seams.

3.Click on the little head and your map should appear! See image;


Do not hit the Validate button just yet. We want to make sure our map isn't tangled. This will happen if there was a mistake made when selecting the edges of our bottle.

Step 7: Validating our Map

Click on the area with your unfolded map and then click on the single view pane.


You can see our map is off the grid.


We need to size it down so it fits on the grid. Before we do that though we need to make sure our map isn't angled. Just use your pan tools and zoom in and pan to the right to check your pieces. If there are no overlapping areas and no tangles you may validate your map. Once that is done it can be resized.


Step 8: Resize and Position

Here is what my map looks like zoomed out. Now that it is validated I can use the selection tool to select the entire map and size it down. You can either use rectangle mode or lasso to select your map.


Right click and drag to select the entire map and then resize using the Universal Manipulator's center yellow square. Click to deselect.


Now you need to zoom into your map and select each of the pieces individually and place them onto the grid. I think it's easier to use the lasso tool for this step. Do not be afraid to resize or rotate the pieces as needed.


You have mapped your bottle!

Step 9: Export and Save

Go to file export wavefront object and give it a name. I used these settings;


Step 10: Using UV Mapper

For this step you will need to use a UV Mapper. You can pick it up for free at

Open up UV Mapper. Click on File/Load Model and navigate to your folder where you saved your mapped bottle and open it. Your map should appear without a problem. To save it as a texture map go to File/Save Texture Map and select the size you want. I chose 1200 x 1200 bmp and left the boxes unchecked.


Don't worry if the map looks a little distorted it will look fine in your art program.


Step 11: Checking Our Work

We need to check to see if our map will work so open up your map in Paint Shop Pro or Photoshop or other art program. Save your map with a new name for editing.

Use the magic wand selection tool to select the white area of the map and then click on select/inverse. Create a new layer and leave the selection activated.

We are not going for anything really fancy here as this is just to test the map to see if it works. Just use the flood-fill tool to fill in all of the pieces with color. Merge/flatten layers.


Save the texture map and exit your art program.

Open up Poser 4 or above and then import the wavefront obj of your bottle. Leave settings at default. Drop object to floor if needed.



Click on Render/Materials and then click on load texture map and navigate to your model/map. Click on OK.


Render your image to see if your map worked. If all went well then your bottle of wine will look similar to mine!


Congratulations! You have finished the Unfold tutorial.:o)
