no, just head over to the "lights" tab and select "no environment" from the topmost dropdown box where you currently switch between other environments.

you open the common tab, and somewhere in the middle there is a single line text box called "surfaces filter"; every word (comma separated) that is entered will be used to filter surfaces out (using wildcard style & case independent, so "cornea" filters out something like 5_Cornea). this is needed, since it is not possible to hide individual bones of a figure. click the "set" button, to immediately apply the filter (changes in the box are saved as soon as typed).

you are welcome

right click the cornea surface entry in the right tree (daz surfaces), and click "create as new" - it'll create a new auto material for that single daz surface and will unlink the current octane material. you can do this for 1-n selected daz surfaces. if you have more than one selected, and use "create as..." it will also apply mat grouping if needed...
