Enjoy Star Wars and Sci-Fi so decided to try my hand at creating a Star Destroyer as my first project in Blender after watching a YouTube tutorial by CG Geek. I thought how hard could it be to learn Blender and try a variation on the classic one by trying to model one from the prequels… Several weeks later, I now feel that I am in a position to look for feedback on lighting and materials and other thoughts. I used some stock metal texture and grunge textures from a texture website and a couple of spots used the displacement map created in the Star Destroyer texture, but all of the hull plate displacement maps, otherwise were created in Photoshop. Textures for the Moon, Earth and the galaxy are from NASA and the ESO.
In particular, I would appreciated and comments or recommendations on improving texturing of the displacement maps. I am having issues with creating displacement maps that was using 50% grey as a neutral height. I was using 8-bit RGB png files with Hex 808080 as the baseline but needed to subtract about .4 to .45 to get the displacement to map properly. There was still some wonkiness though as you can see in the engines that light is leaking through.
I think I am not looking at any major changes to the model, but would appreciate any comments that could improve the look without fundamentally altering it. I’m not particularly interested in how well it aligns to the actual Star Destroyer in Episode 3 as I became aware of some glaring differences once I moved from basing the model from a design that I found on Deviantart to watching the opening sequence of Episode 3 over and over again.
