I got it all worked out from above but now im noticing when i play it in ue4 it pretends like my blender model is a huge block? i cannot walk on the flat seams?Have them set to blockall also tryed ground for collisions in ue4. I walk up to it and try to walk over road and it just acts like one solid block? Also building acts like a huge solid block? im not sure if this is blender or ue4 issue a bit new too both.
