I pretty much got the model untouched from Sketchfab but I removed the landing legs. I’m still a novice to Blender so I don’t really know how to make textures, models and stuff.
At the end, anything that looks weird will always be hidden in motion. A good motion blur + match grain from the original Blu-ray would hide any “over-perfections”
I’m also trying not to make it look as real as possible, just trying to line it up with the visual aesthetic of the film. TROS isn’t too overly-photorealistic with its VFX (and they probably didn’t care nor have the time to finish it due to the rushed nature of production) and so anything floats under the sun.
