Is it possible to check the alpha channel of a rendered image in the Solaris viewport? I can check all the AOVs with the side panel menu, but I don't know how to inspect individual channels, like R, G, B or most importantly alpha. The best I can do right now is to make a snapshot double click it and check the alpha channel in the Render Gallery window. Is there a better way to do this?
In the "persp" menu in the viewport, turn on the "Correction Toolbar" toggle. This gives you basic brightness, contrast, and other image-like controls for the viewport (including choosing which color/alpha channel to show).
