Make grey background while using HDRI for renders 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 &quot;Environment Opacity slider&quot; 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
The best way is to use film-&gt;transparent.
Now go into compositing section and click on use node.
Add an alpha over node before output node and chose your desired color.
This way,the render will use the HDRI and then make background as chosen in the apha over node.
Also,if your entire render comes as single color,try switching the color inputs of alpha over node
