I'm sure as things progress there would be more. They're the main problems I struck in my little VR hackathon. This is an area you might get some traction with modders in general, as nice 3D versions of hands and weapons could be used in base game as a mod also. All need models to replace the 2D overlay animations. You'll need to rewire the UI back-end to render to an offscreen surface then present that on a diagetic quad the user can point to with the controller.

GUI - The non-diagetic UIs in DFU are hard to port into VR.No perfect solution yet, although when I bump to Unity 2018.1 next month it might offer some more options. You can use deferred with FXAA and Temporal AA in VR with varying tradeoffs. This means you either end up with flickery lights with AA on forward or great lighting with no AA on deferred. Lighting - VR looks best with forward rendering and lots of AA, but DFU is deferred for all those point lights.I've had a bit of a play with this on my end as well (have a Vive not a Pro, so jelly) and there are a few really sticky areas. While the modding system is plenty powerful, the needs of VR are so integrated across the whole game you're probably better off going for a fork and building in the changes you need. You might have a hard time working in VR as a mod. By the time I'm done with 0.5, we'll basically race through 0.6, 0.7, 0.8 milestones in one fell swoop. All these other game systems (guilds, commoner quests, background alliances, banking, renting tavern rooms, buying houses, guild services, etc.) have all come online while I've been in the 0.4-0.5 tracks. The project has attracted some wonderful contributors in the last couple of years and is building out at a fast rate. Things are going great with Daggerfall Unity! Quest system almost completely operational and magic effects are being written now.
