hi guys, sorry for my bad English.
I have a problem to set correctly the CoronaShadowCatcherMtl.
The plane with this material is visible in render and alpha channel not work well.
The lighting is created by 4 planes (4 windows) ad a hdri (for reflect).
"test.jpg and test alpha.jpg" are the images (for a bed test)(set alpha mode "Always transparent"):
And "for compositing.jpg" is the image if set Alpha mode to "for compositing".
What's wrong? I have little experience in this...
