Scene units for Pool Balls with Scratches Blog Post

[HaroldL]

Can someone tell me what the scene units are for the pool ball scenes in latest blog post "How To Create Subtle Hairline Scratches in KeyShot"? I downloaded the bip file don't see any indication of the scene units. I tried the indicated settings on a model I created in inches and got some very different results. Usually when I import a CAD model into Keyshot the units show in the Scene Units menu, that's not so with this model

Hi Harold,

The bool ball scenes are indeed unitless. I made them in a pretty "quick and dirty" fashion, importing spheres (Edit > Add Geometry > Sphere) into a new scene, thus rendering them unitless.
Adjusting the Scale of the Scratches texture should allow you to easily fit the texture to any object though.

Hey Dries

Can you explain how the direction field -> normal works.
Why does the scratches in the realtime view look different to the scratches when i hit preview color on the note?
