Took me about 400 hours to create this model, and spend a lot of time searching in NASA's public archives to get diagrams and info i could rely on.
I tried to be as much accurate as i could be. Placing each individual thermal tile, pad and pieces where they need to be placed.
Thanks to Substance painter i was about to create detailed PBR textures to work with in Blender Udim feature.
