This might be a noob question, but I could use some advice. Basically I've been having a really difficult time figuring out how to get DynDOLOD to generate the 3D LODS for the Happy Little Trees Add-On. I've upgraded to DynDOLOD 3 and I've made sure I've downloaded the corresponding DynDOLOD 3 Resources, PapyrusUtil AE, and the base Happy Little Trees mod. I've made sure both HLT and HLT 3D LODS are enabled and I run TexGen and DynDOLOD and enable both outputs and with each attempt, I keep getting 2D billboards for HLT, not the 3D ones that I've installed. I've made sure to sort my load order with LOOT also. Maybe I'm missing a step, idk. Any info would be super appreciated. Thanks!
