Render Transparency in edit mode I am doing some modeling with blue prints. I would like to see the blue prints through my mesh. However when I switch to edit mode the transparency is no longer rendered. How can I enable transparency in edit mode? Or is the another way I can see my blue prints through the mesh? 



I am using blender internal.
First make sure you choose GLSL shading mode in the properties panel of the 3D view (shortcut N):



Then, you can switch the viewport shading method to Texture in the bottom menu:



Then, your object will appear transparent (if you set up the material correctly ;) even in edit mode.
