I noticed in the Lights topic of the User Guide, in the 'Samples' section it states this:
"If the issue is noise in a specular highlight, you will need to confirm that the source is the direct light and not a secondary ray type (such as glossy). This is easy to achieve by turning off global illumination; set the GI_diffuse_depth, GI_glossy_depth and GI_reflection_depth to zero (this essentially turns off all global illumination). "

After searching around I can't find anywhere else mentioning how to turn off GI in Arnold. Where do I set 'GI_diffuse_depth' etc?
