If you are an Arnold user and a Windows 64 bit user then you might be pleased to hear that the newest emTools (v.1.910) is shipped with an Arnold shader called "OSO". Here the brief description taken from the online doc:
It has two different shader modes that were developed during projects with Framestore and Polynoid respectively:
- OSO (Outer Shell Only)
This mode can be used to render crystals. It bypasses the internal ray depth counter so that one does not have any trouble with the ray depth when rendering things like for example tons of transparent intersecting cubes. - PLND (Additive)
An additive rendering mode that is well suited to render strands or particles with a "glowy" look. The picture below shows strands that were rendered with this mode.
That's it for now.
Take care!
