Lightning reflections

Hello everyone. I would appreciate some help in a subject of light reflections. I am new to UE4 and I do not know what I should do to make the light of one material fall on another. I leave a capture so you can understand me better. This scene is simply that chrome spider with two lights on it. The problem is that the underside of the spider does not reflect the pink hue of the ground. Instead, it seems to interpret the ground as white (which is the color it has) without interpreting that it is illuminated and reflecting it in turn the pink-purple color. Would it be something complicated to achieve for a newbie? I come from other programs such as 3dmax where all this does a render automatically and I’m a bit frustrated.
