Hey guys! I'm trying to get STEP installed for a more stable playthrough but I've had some issues and questions - first of all, does STEP require every single mod? The two I'm worried about are ELFX and the Skyrim Rebirth HD textures. I know I want to use and enb, but elfx will compete with it, and I'm worried the HD textures will be a little too hard on my machine. Also, I've noticed Step has no female body mods - is it safe to install UNP with it? Thanks guys!
