Any ideas how I can create an X-Ray car body similar to the one in the attached image (rendered with Vray)?
X-Ray Material with Arnold
There is a tutorial in the Arnold Help:
Scroll down to Stylized Shading.
To get an effect like in your image:
in the Facing Ratio map, check Invert, set Bias to 0.95 and Gain to maybe 0.2.
In the Color Correct map, the important parameters are Gamma and Exposure, maybe 2.0 and 1.0 resp. Change the Multiply Color to your liking (you will get the opposite color!).
Very important: In the Render Settings, increase Transparency Depth to 20 or more.
