Object turns black when applying a material

[znk (zеnk)]

For some reason when i add an object to the scene it becomes black, but in preview it looks completely fine. Any solutions?

Reflection capture?

Your normals are wrong. You are taking the cross product of DDY and DDY.
You need the cross product of DDX and DDY to determine world space normals.
