hi,
when I apply a shadow catcher to a surface and reference it in environment mode to a sky with HDRI material, everything is fine until I change something to the HDRI material.
This can be changing the intensity of the light material or inside a filter shader.
Only solution to continue is restarting IR
so for the included test file:
1) start IR
2) change the intensity of the sky, and surface becomes yellow
when using the hdri directly in the sky, I can change the sky intensity or change color in a filter shader without it turning yellow, but if I
1) duplicate the sky
2) put the second sky in a null
3) make the null invisible (with second sky inside)
the floor surface with the SC turns yellow again
I don't know how this responds in v7, but it is equal on R18-R19 and R23 with v6.1
