Acura NSX 2017 - Studio Front 3/4 - Utilising a Maya & VrayRT / GPU workflow combined with HDR Light Studio I was able to achieve the desired result in a much quicker time frame (although Maya's new render layer system is still giving me a few grey hairs!)  The renders were processed in Photoshop almost completely in 32bit only coming down to 16bit for the final post-processing and effects stage.  Hope you like it!

*UPDATED - Just updated the paint finish to add a bit more pop and some paint flakes
