I know from experience that if I change the plugin to suit one user, I get 10 angry emails from other users who do not like the change
If I change the material picking to the right mouse button, that will be inconsistent with all other picking functions and Octane Standalone. And I don't think the right mouse button is used for any other function in the Modo plugin. So I would prefer to implement a solution which is intuitive for users, and consistent with the rest of the plugin and Octane Standalone. I think the best solution in this case it for the plugin to match Octane Standalone, but I will need to do some reworking of the system which will need to wait until I have all the Octane 4 conversion work done.
