you can laugh about me now … but i cant even reproduce that ^^
what i did :
i opened blender.
under “metric” i changed “scale” to 0.01 (so that1meter in blender is 1 meter in UE4)
i rightclickted the default cube and changed the size to 10meter * 10meter * 10meter
then i pressed “a” for select all … then control+a to set the scale from 100 to 1
i changed to “composite” view … pressed “a” to select the whole cube … then “mesh”-> “uv unwrap” → “unwrap”
then i eported it and imported it into UE4 … works fine … cube has the correct size …
if i try to put a material on it and press “build” -> ERROR (uv overlapping somewhat and the material is scaled to much)
then i tried to do exactly what you said but :
i) the default cube is tiny in UR4
ii) 3.how do i export the texture ?
iii) when i have to drag and drop the texture/material in UE4 on the mesh - how does it work with more material ? lets say i build a house in blender and i have textures for a door,window,wall …when i export this mesh then import it into UE4 i have one object… and when i put a material on it it will cover the whole object
