Strange reflection (plane outside + hdri in envi)

[jacekszy0]

Hi,
I have problem with very simple scene  when using hdri map in environment and plane with texture outside. Guys, look at preview:



Scene preview from top (nothing special):



And glass material in window (pretty simple):



Of course i disabled "cast shadows" and "receive shadows" in plane. I test plane material using default corona material and corona light material. Both makes reflection like this. Plane material is of course simple corona material with diffuse map.

And now question is: why floor has reflection from hdri in environment slot (clouds) not from plane which is just behind window!?

Enable cast/receive shadows for background plane and plug its material into CoronaRaySwitchMtl's reflect/refract/direct override slots and assign that RaySwitch material to background plane.
