Here are the steps required for exporting a textured object from
Blender3D to Panda3D (NOTE: You have to use Blender versions BEFORE 2.5, because the Panda exporter doesn't yet work in 2.5 or later). If you have access to MySchool, you can view these steps in action in the video that has been uploaded into the course there under “Demos”.
Configure your Blender 3D environment by “dragging down” the top menu bar to reveal configuration options. You may want to change “Selection” to “Left Mouse Button” and rotation to “Turntable”
Select the cube (Left mouse button if you have changed the configuration, Right otherwise)
Name the selected object “Box” (press “n” for the “name” box)
Switch to Edit Mode (The mode selector currently shows “Object Mode”)
Switch to Edge Select Mode (Three buttons on the bottom bar of the window: vertex, edges and polys)
Multi-select the “seam” Edges of the Box (for a fold-out cube)
Mesh→Edges→Mark Seam
View→Front
View→Orthographic
Split main window (RMB on bottom line of window→Split)
Select “UV/Image” view for new window
Select your object again in the 3D view (press “a” to select the whole object)
3D Window: Mesh→UV Unwrap→Unwrap (you should now see the fold-out texture from the cube appear in the right UV/Image window)
UV Window: UVs→Scripts→Save UV Face Layout..
