light test and texture

hi all
i try to rendering with UE4

i have a problem with reflection meshes
like this

the reflection curvig in the middle and this is obviusly wrong. have to be vertical like scene axes

i don’t use any reflection thread
i don’t use specular in the material (just roughness)

why UE4 create this wrong?

thx all

Reflection is angled only when the floor is angled , that’s when the problem appeared to me when using decals on non flat terrain .

Normally this should not happen, but check if the compression setting of the normal map is TC_Normal! I had this bending of reflections as well when my normal maps had the wrong compression assigned for some strange reason.
