Exporting the model is not the problem. It was easily export and import to Pepakura in .obj format. My hurdle was exporting the mesh alone with textures to Pepakura.
But, I got it now. Seeing my wife enjoying her friend’s baking video on Facebook, it drawn on me that I can bake the textures to the model and export it in all it glory. I recall I done it once, but it was centuries since I practice this dark sorcery. Such knowledge was lost and I only hope to regained that valuable knowledge one day. But with that knowledge lost, it tiger something else in my deep dark memory bank . There is more then one way to cast a spell. So I saved the .dds textures on it own and then save again as .jpg. Place .jpg textures files in Pepakura, done! Mission accomplished! Well… not really. There is much work need to do to make the model unfold friendly. But I jumped that hurdle, I’m happy.
