x61 record 3 is definitely coded as a window. This will include 061, 161, 361, 461. I'll need to look into why some of these don't gain emission, but most likely the windows byte index isn't what the converter is expecting.
But you are absolutely correct about the Mages Guild in that older bug report.
I missed x36 record 3, which is why the Mages Guild in earlier bug report doesn't gain emission. I've just
fixed that one now. And also had to create a special case for TEXTURE.036 as window is at index 2 instead of 3 like everywhere else. Bloody Daggerfall...
Edit: Had a quick look at Woodborne. x51 isn't a general window, it's a special case at 151. Have another case at 351 for Wayrest, but no 051 or 451 window. But even when coded as a window, converter doesn't find any matching emission pixels (usually 0xff) for 151.
Edit2: Confirmed Woodborne 151 doesn't use index 0xff like it should. The window area is painted with index 0x7e... and so are other parts of the texture. Trying to use 0x7e to set emission will also result in some glowing brickwork. This one is a data issue. With that said, it's still possible for DFU to recognise this as a window and use a modded emission map, even if the classic art doesn't contain the correct index. I've added those items now. They won't show up in unmodded DFU, but DREAM should be able to mod them in 0.11.0+. Based on your comments above though, I'm not sure how well this is going to work. It sounds like the emission colour still isn't being set right for x61, and this one falls into the same category. I think we'll need to revisit this one later.
As usual, we're fighting different problems all over the place in those old assets.
