Faux Neon Sign is screwy when placed in a window :(
Note that you can't have a texture that's semitransparent with this method. You won't get any subtle antialiasing that goes from being 10% transparent to 25% to 45% and so on; the parts of the texture are either not transparent at all, or completely transparent.
You can look at my Leefish mobile if you want to see how it looks "in action".
Of course, if that doesn't help, then I'm at a loss without looking at the object.
After posting this thread I had the idea to make a non-transparent recolour of the window (it's supposed to be blacked out anyway since it's a vampire bar) - I may still try that to see if it works.
@Lee - No I didn't try any other windows since that's the window it needs to be in. Pretty sure there'd be no difference though.
@DutchXfan - I cloned a poster because its mesh is the right shape and size so I wouldn't have to make a new one - just had to edit it to remove the wall shadow and permanent tape from the poster's corners. The only difference between a curtain and poster is that you have to hold down ctrl-alt when placing the poster over a window (or use moveobjects if you don't have AL), so I thought using the poster would be easiest. It's not something I plan to upload anyway since I'm pretty sure I'm the only one who wants a faux-neon fangtasia sign so I just went for the simplest option.
I think the not-transparent window recol should work. It shouldn't be necessary when the texture isn't transparent, but just to be on the safe side I'd change the stdMatAlphaBlendMode to none anyway, so that it doesn't just look transparent to human eyes (undead or otherwise) but to the game's as well. Then the game shouldn't have anything to complain about.
I don't think you're the only one who wants this, though. It looks great. I'd love to have it as well, and I'm sure there are True Blood fans out there who'd be thrilled.
Just need to redo my non-transparent window recolour because someone apparently repositoried their awesome window to a door so I accidentally recoloured the wrong master.
