I just finished putting the final touches on the 3D tower model in Blender. I decided to document some of my backend work on the model with FRAPS and show of the tower with an turnaround render. This is what I got after merging the two videos in Camtasia:
From here on out, I need to figure out how to import this model into Unity 3D. From what I've looked at so far, I need to bake the textures onto the model, and then put the .blend file into the correct Unity project directory. Apparently, Unity reads .blend files natively, but I'm sure that I will uncover some interesting problems as I import the model.
