After multiple searches and video tutorials watched, I'm still not quite grasping how the 'Opacity Mask' function works in Community Theme Creator. I did watch the 'Applying color tint and opacity mask to an image.' video from the JaysArcade tips post. I'm also very familiar with photoshop mask functions, although it 'seems' like the CTC version works a bit differently. My initial intent is to use an Opacity Mask to grey out (e.g. reduce opacity) of non-selected wheel elements while keeping the selection at 100%. (Some older posts seemed to suggest this was feasible, but didn't get into how.)
Is there a more comprehensive explanation or tutorial the delves deeper into the function or one that potentially shows how to do what I've described above?
Thanks
