That's from the CBBE mod description/FAQ. Any 'guide' that tells you to use XPMS is wrong and should be ignored. So. 1. Install CBBE. 2. Install HDT PE + whatever else you want related to that. 3. Install XPMSE and all its requirements. 4. Install BodySlide. 5. Open BodySlide, select 'CBBE Body HDT' as the Outfit/Body. Pick or create a preset, then click 'Build'. I can't see the option to "CBBE Body HDT" in bodyslide I have tried everything :(
