Datasmith livelink is a powerfull adition that is still work in progress, but i have recognized a big issue that makes it wortless to use at the moment, I use Rhino3D when i model and when i use livelink in unreal engine i texture the geometry, but the second i isolate or hide objects in my view in Rhino3D, livelink syncs but now the textures i added in unreal engine are reseted to default.
so i need to retexture but there is no point to do that because once i hide an object in view that i have textured it will reset. thats a big waste of energy and time,
i hope you can look into it as part of your development.
thanks
