hi guys,
Im busting my head for 2 days now, surfing the net to find a solution to my problem but no luck.
Im using Vray. I have a problem with the vray wrapper. As you can see in the screenshot, i get the reflection of the car on to the vase and also the ground shadow of the car BUT i can also see the reflection of the groundplane where i applied a shadow catcher and thats not what i want. How can i fix this? i hope its clear. i just want the car and the shadow reflecting on the vase without seeing the shadow catcher with an alpha so that i can comp it in nuke on to the plate.
thank you guys, plz some help

I think you’ll have to render a separate mask to separate the car+shadow from the ground.
Make the ground completely white and the car completely black and use the resulting reflection as a luma-key. I’m not sure what you’re compositing with. Remember that a reflection is always additive, ie. ‘screen’ or ‘add’, never ‘multiply’.
I hope this helps.
