Searched for some time to find a no sun damage mod, and came up dry, so I decided to make my own.
For the OpenMW version, I just adjusted the vampire sun damage value from 5 to 0. This removes any damage for being a vampire, but equipment that adds sun damage (I believe a tribunal item adds sun damage) will still do sun damage
For the original version, all I did was change the value of sun damage to telekinesis for 5 points (as simply removing the slot altogether glitched it out for some reason). I am not aware of any compatibility issues, this is something I spent 30 minutes setting up. If there is any issues, let me know, but from what I've tested this should be fine. I do not know if this will effect NPC vampires you get from the 'vampire embrace' mod.
