I am trying to create a basic shadow catcher material.
First Scene:
When I use a Dome Light with an HDRI it works great with vrayproprieties into a "shadow catcher" plane as you can see in the first image.
The second image is just the gi contribution of the matte that gives a "strange result".
But in this exemple: Sucess!


Second Scene:
Here I created a basic geometry to represent the HDRI and then I projected the HDRI with a spherical projection node into a vraylightMtl. I have GI lighting the scene from that Geometry with an hdri.
This way I get more correct lighting and reflections (I guess)
But in this exemple: NO Sucess!
The first image shows that when I remove the GI contribution from the matte surface proprieties, I get no shadows/occlusion.
In the second image I leave GI contribution on but get that "strange result". BUT I get some shadowing/occlusions.


How can I get the second scene to catch shadows/occlusion but not that strange result?
NOTES
-I am using Irradiance Map + LC in both scenes with basic settings.
-There is some basic info attached to the images like the alpha and the environment that may help to solve the problem.
Thanks in advance
