Forensic Case: How to generate a virtual X-ray with Photoshop?

Notice the image below:

It is a virtual cranium with injuries (done in Autodesk 3ds Max) and I would like to to use Photoshop in order to generate X-rays as similar as possible to the ones from the real patient's autopsy:

Import it to Photoshop.

Unless the density has been mapped you will not get a true X-Ray. All you will get is a simulated effect based on making the model translucent and assigning a density to it.

For the materials set Glow 0 , Metallic 0%, Roughness 0% Opacity 100% Refraction 1.0 , Density (You will need to play with this) , Translucence 100%

Set the infinite light to shine from behind the object (at very high intensity ) and the camera to orthographic.

Then put an invert adjustment layer above the 3D layer.

Let's elaborate. I am convinced that taking the screenshot from 3ds Max as seen above directly to Photoshop is a poor workflow. The problem is that the frontal osseous material completely obscures the posterior one.

 

I don't know about the internals of 3ds Max transparency implementation but I hope (Autodesk folks: consider this a feature request) that two layers of bone would be denser than a single layer.

 

The current virtual cranium has uniform bone thickness. Future versions will be more realistic, incorporating varying thickness:

(a) Provided by mother nature

(b) Provided by the projectile.

To be sure, are those Photoshop settings? The reason I ask is because I am somewhat familiar with 3ds Max (and related apps: Maya, Cinema 4D, Blender, etc.). They have parameters like those above: metallic, etc.

 

Thanks!
