Yes indeed, it was a lot of work. It took a whole school semester of 10 weeks. The details in the 4th and 5th picture are sketches made by hand. And I gave them a color in Photoshop. The 3d details below these sketches are rendered in Vray. The materials are named in indesign. Here is a simple interior render I made this morning for a presentation tomorrow. I ain't 100% satisfied with it, but the purpose of this render is to show how the steelwork was formed and to understand the details better. [image: interiorpsd.png]

Hmm, the problem you have circled is probably you just need to smooth the geometry. But I think you ought to start with the disco lights issue first. Are you using emmissive material for lighting? Try using a spotlight instead for your light sources and that may help.
