It is not CAD but I was only going to cover it in dirt anyway. The only thing I added were the grill meshes.
- The cloth simulation simply does not stand up well enough for the type of material I wanted to produce, I relied a lot on adding texture in post.
- Car model is not CAD and there are a few inaccuracies, for this purpose it was great but for high resolution I would want to do more work.
- Dust as mentioned above
- Some render issues the more experienced of you will be able to point out.
Overall I am quite happy with the final outcome, I have learnt a couple of new techniques applicable to future professional and personal work.
Hope you like it!
