Having issues with purple tree trunks on pine tree's, purple crystal like things on the ground in snowy regions and purple rain. I've checked that my SFO is installed correctly. I made sure I didn't accidently rename the treepineforestsnowl03.nif and treepineforestsnowl04.nif which seemed to be an issue for some people. I also double checked that I only installed the needed files for SFO. I went through and made sure the original mod files dealing with tree's and flora was still checked in the left pane, (i.e. Vanilla Enhanced Trees is still checked). At this point I'm not sure what to do. Help would be greatly appreciated.
Figured out the fix for my situation. Will leave this here in case someone did what I did; I downloaded and installed Skyrim Flora Overhaul SE v2.72a and the Trees Only Version v2.72a and that was the issue. Deactivating and unistalling the normal SFO and leaving trees only version fixed my issues. Cheers to Lexy and all the others for the awesome guide and help given to people!
