Invisible Dragon Glitch?

[Brushie]

So I just finally had the patience to re-start Skyrim from day 1 and remod it. It's been going great for about 30+ hours or so, but now I've been running into a problem I've yet to see. The dragons are invisible (Or at least very translucent. I can see odd minimal brownish textures from them, so they're not -invisible-, but they're damn hard to see.) and I haven't a clue on how to fix it. I've tried searching it up a few times, but there haven't been any solutions as of yet. I'm really not looking forward to having to reset completely again (Done it a few times already, due to either corrupted saves or dickish friends). Any idea what to do?

I am not sure how to fix the problem, but the problem could be that far away dragons use LOD textures instead of the higher quality textures and there may be a problem because of it.

You can try this mod and see if it helps, otherwise I have no clue.

I had the same thing happen to me. I was getting attacked but the dragon was nowhere to be seen. Are you using any dragon mods like Deadly Dragons?

I don't know why but that turned out to be my problem. I deactivated Deadly Dragons and the became visable again.
