Shadow catcher plane transparency problem in compositing I'm new to blender and need some help with compositing. I tracked a video footage to camera solve and placed a 3d car in compositing. Shadow catcher plane showing world background on my footage floor under the car instead of showing shadow on floor. Shadow catcher plane is casting shadows but cropping my footage floor where shadow catcher plane is placed.
To alpha over your rendered car and shadow above your footage, the background needs to be transparent. Go to Render Settings &gt; Film &gt; Transparent and enable it.
