Boolean and Opacity

 
I created a 2d outline using the sline tool of a window. I used smooth tool on the top edges to make it rounded like a window.
 

I use the UVW map modifier tool to make a solid shape and extruded it to make it 3d. I move copy the shape to make 2 of the same shape. I used the scale tool to make the shape smaller to make the hole for the window.
 

 
I copy the smaller shape and scale the second one thinner to make the glass for the window. I scaled the first smaller shape thicker so it can intercept the big shape.
 

When the shape was being intercepted I selected the big shape and went onto compound objects tab. On this I chose boolean and used operation subraction (A-B) to take out the thicker shape to make the hole.This hole is the same size as the thinner shape so i just move that into the hole to make the glass.
 To make the glass opace I go on the material editor and put opacity on 50 to make it half transparent. I then go on photoshop and make a tiff file which uses the alpha channel. I put this tiff file in diffuse map and opacity map. On both maps I choose Alpha source image alpha

Texturing Objects

Textures
 
Material Browser selecting bitmap

To make a 3d model look realistic and look like its meant to , you need to texture the object. I had to make a crate and make one look like a metal crate and a wooden one. I select diffuse colour and select bitmap on there.

The texture on the sphere
When i select the texture that I've chose it puts it onto this menu. Before I put it on a model I have to select show shaded material in viewpoint.I then repeat for the second texture.

This shows both of the textures. To apply them to the model I just drag which one I want onto the correct model. This is what it looks like below.
 
To make the texture mapped properly I had to modify it. On the modify list I need to select UVW Map and select the "Box" mapt  




 
When making my own texture for the sphere I had to use a different mapping style on the UVW Map modifier


Here is the comparison between my bitmap and what it looks like on the object.
