Level Design in UE4 is slow and tedious.

  1. a beginner tutorial (just when you havent used blender before :)) e.g ?

  2. Rough steps:
    -create the mesh with the right scale 1cm=1uu
    -uv map it + create the textures ?v=f2-FfB9kRmE
    -create a collision, a lightmap and lod’s -> ?v=17pcyPVplEc ://
    -export the mesh (default settings) + the textures (you can save them from the UV editor)
    -import everything
    -do a right click onto the texture and create a material -> ?v=lngF4VVNER4&list=PLZlv_N0_O1gbQjgY0nDwZNYe_N8IcYWS-&index=1
    -assign the material to the mesh (double click onto the mesh in the content browser - add the material to the slots)
