View Full Version : Cant figure this out

I want to make a scene to render a car. I dont want any suroundings Just a grey room. I cant get the shadow catcher to blend in seamlessly to the background.

Even when the background has the same RBG values as the shadow catcher, it still wont blend.

well, assuming there is nothing behind the grey plane, there should be an alpha for that and you could just take it into photoshop or after effects and put the correct grey background in

or you could replace the plane with a subdivided box.

Might use fog set to 'use backdrop color' with a min value just beyond your subject and a max value at the outer edge of your floor.

Or apply a 'distance to object/camera' gradient in the transparency or luminosity of the floor.

I decided to use a ground plane that gradually goes up into a bowl. Thanks for the sugestions.
