Hi Ian, I see that you have a shadow Viewport and Scissor attribute structure. I was trying to avoid managing two copies of the data so I just updated all the drivers to use index 0 of the array directly. You'd probably want to do the same thing with the scissor enable flag that becomes a bitfield of enables. Changing from Viewport to Viewports (I used ViewportArray) in the drivers touches about 20 files. Have to touch those same files when removing the x,y,w,h arguments from Viewport and Scissor anyway so I figured it was no harder to change the references to Scissor and Viewport to be array references to index 0.
Shall I just post my changes for folks to poke at? Or is a fdo personal repository easier to work with?
