Updated shot, of all the assets I've been working on with my mansion. The mansion is so large in scope, I'm really trying to do it one section at a time. Here I've added in a lot of ceiling molding, extruded walls, arched windows, etc.
This is a model and wireframe close shot of the arched windows and molding on supporting columns. Window frames are in place and beveled.
Here we have the crown molding running across the top of the ceiling and also across the extruded walls/columns.
And here we have the magic lol, but once again thank god for curves. I did a lot of research on molding/wood trimming/ and other designs that I really didn't have that much knowledge about before. I grabbed 2D shots of the profile of these designs and made curves out of them in Maya, after that it was just a matter of placing these curves in place, and lofting them to each other to get what I needed.
