I just want to ask if anyone knows how to make background grey while using HDRI so it would be the same as in Substanse painter "Environment Opacity slider" or basically the same as in Material Preview Mode in Blender?
Is it possible to make it without options that listed below?:
Not a transparent background and then add grey background picture in photoshop;
Not a heavily blurred background (I found this option here but it still has colors);
Without adding a grey plane at the back while rendering
Just pure grey
