Shadows on HDRI

[leo64]

I'm using texture environment with HDRI images. When I have an object without floor seems that it's floating. Is there any way to the shadows appear on the HDRI image like in the picture below?

Thanks in advance.

Make a plane that would act as the "ground" under your object.
Apply a diffuse material and check the "matte" option. This will turn it into a shadow catcher material
