Hi. Im looking at render a very simple scene, where I need the transparency where there is no shadow or object. it should be transparent.
Now I use a Shadow catcher as compositing, and it looks good until you put it on a website or background. even without an environment and only a light from above the shadow bleeds out far out and it creates a suddle edge.
And I don't want to use a render element and render the shadows separately because Im gonna render a couple of thousands of renders.
How would you guys go about it?
PS, changing the shadow amount doesn't do anything for me.

Why don't you just expand shadowcatcher plane, so its edge would go beyond camera's field of view?

This depends on lighting. If there is some shadow cast at that area, it will show in the shadowcatcher. Maybe you could try to make some adjustments to the alpha mask of that image? For example add more contrast to it.

the plane go past the camera, but I don't want the shadow to bleed out so far towards the edges.
What I ended up doing is to setup a light that just affect the shadow catcher, and then a DOME light that only affected the couch and didn't cast shadow, since you cant tell a HDRI to not cast shadow on a object.
That did it.
