Hello Community,

i ran into a little issue regarding the shadowmatte shader.
I want to render something out that has reflections from an hdri and is placed on a background plate from the same shooting. (Car on a road)

I can use the shadowmatte to get a shadow in comp but the reflections in the object dont show the shadow the object is casting. So if i have a chrome sphere sitting on a ground it shoud reflect its own shadow being cast on the asphalt.

Is there a way to get this working, so basically the ground plane picking up the background image as a texture , with shadows on it (ideally colored shadows of course) ?

Thank you for your help

Hi,
Your confusing what a shadow matte does. Make sure your faux ground is visible to reflections , if you have no reference material to re create the road , just project the plate through the camera. Then you can get better contact between the plate and car model.
