Julia - Quaternion not converting

[vjanomolee]

Hiya! Thanks so much for making this tool.
So I'm trying to get this shader working: https://www.shadertoy.com/view/MsfGRr

and I get this error message after converting:
Shader error in 'ShaderMan/Juila': 'abs': no matching 3 parameter intrinsic function; Possible intrinsic functions are: abs(float|half|double|min10float|min16float|int|uint|min12int|min16int|min16uint) at line 101 (on d3d11)

Any help appreciated.

Also- Is there a way to have Unity lights affect the surface of the object in the shader? Or a way to expose change of color and or material properties like roughness/ metalness/ specularity?
