PLANCK is a very recent mod, so not got around to trying that yet! Trouble is with a 200+ modlist is that new mods can cause extreme breakage.
I installed all the mods myself in Skyrim VR using the Vortex mod manager. What a painstaking process that was!! I went back this week after 6 months, and updated all the mods etc. Game still plays but crashes to desktop every couple of minutes. So something has messed up, probably me, because I couldn't be bothered going through the description of every mod to figure out which one should be loaded before which other mod. I couldn't remember.
So, I have decided to restart. Have removed all the mods from Vortex and returned the game to vanilla. Now I am in the process of downloading Wabbajack and have picked the Ultimate VR essentials modlist. Hope this makes it easier to update and remove and add mods than doing it manually in Vortex.
