Hello Nephanor,

You mean the "Eye Axis R/L" and the two "Diopter" props which are attached to the eyeballs?

The purpose of those is to provide a guide to adjust the direction the eyes look, so they are not "control props", just a tool.
The geometry consists of one long thin cylinder (90 polys) per "Eye Axis", and one disc (30 polys) per "Diopter".

By default these are hidden *inside* the head, behind the eyes, and scaled down to almost 0%.

They are controlled by the -Toggle "THE LOOKS" parameter in either eye. Set the parameter to 1 and they appear, set to zero and they collapse.

All parts are set to:

castsShadow  0
visibleInReflections 0
visibleInRender 0
visibleInCamera 0
visibleInIDL 0
 

by default.

If you still think they could hamper your render you can delete them altogether with no problem: They are just parented props after all.

Also read SASHA manual: / Alphabetical List / Other Controls (right at the bottom of the list):
Toggle "The Looks" Off On [Eyes]
SASHA-16/MANUALS/html/pages/11.6. Morph List Alphabetical.html#0707

Would it suffice to make "The Looks" invisible with the "Visible" toggle *1) in the props' properties prior to exporting to Octane? (because all other visibility parameters are already at zero, as written in post #2 above)

Footnote *1:
technically the "visibility Visible" node in the actor.
Can also be set in the "Hierarchy" window by clicking the "eye" symbol.
