Blood everywhere would look pretty cheesy if you ask me. We'll leave that sort of shtick to the vanilla DA campaign. The whole grimdark thing is so overplayed that it's comical more than anything else.
So here is the tomb of Kaza (at least that's who I assume it is, seeing as he was holding the Book of Kaza). The sarcophagus lid has been ripped off and tossed aside, and the book forcibly removed from the corpse, snapping off the fingers in the process (as per the original description in BG2):
Here is the tomb for the Nether Scroll lich, reworked from the style of the original in BG2:
There's no sarcophagus as it will need to be an animated placeable, not a static prop. I'll probably post some in-game video of that if I can get it working. If not, I'll dump it in Cuv's lap and let him deal with it.
Decided to add some more basic/plain sarcophagi props. I figured these guys would be buried with relatives and servants, etc., but they wouldn't warrant fancy gold and silver coated sarcophagi, just plain stone ones. Took the existing Dwarf props (which strangely aren't lightmapped) and slapped on a new texture to tone down the Dwarfish-ness a bit.
There are a couple of broken lid variations to represent looting. I also made a pretty serviceable mummy by taking the one buried inside the webbed corpse prop and throwing on a desaturated Fade terrain texture after a UV tweak:
Pretty much done now. Starting to do the game model prep/export.
