The shadows coming from the HDRI rotate following HDRI lat/long rotation. Also there are shadow weight parameters on the light source settings - they can be increased/decreased to change the intensity of shadow on shadow catcher object.

I forgot, there are 2 vray lights. Shadow disappear after I delete them.
Is there a way to make the background white or transparent when using HDRI environment?

Edit: I found by override the shadow catcher can not change the background, how about alpha channel?

Hi Kirgman,
The shadow stay the same on shadow catcher material when I rotate the envHDRI map.Could this be the shadow of default lights in max. or the shadow of envHDRI un-rotated?

Only 2 wishes: round corner and denoiser
