Reflection problem

Hello everyone,

I’m working with reflection and raytrace but i’ve got an issue folowing the tutorial from Unreal webinar.

I can see two reflections on surface. 1 is from the HDRI and the other from the 3d wall, ground rocks etc…which i can see just from a certain angle of the camera, when i turn the camera straight on surface i can only see the HDRI reflection in medium quality. Anyone can please tell me what i’m doing wrong?

Thanks

Lucio
