Shadows on invisible floor

Spoon

Hi guys,

Perhaps this is painfully simple, and I'm just missing something obvious.
If i have a plane under the asset,I cant make it receive shadows when its alpha is 0.

I would like to have my object to cast shadows unto an invisible floor, so when I save with alpha, I just get the asset and shadows, but without background.
Is that possible?

What you are looking for is the Shadow Catcher object.  Scene -> Add Object -> Shadow Catcher.  You just need to go to capture settings and enable Transparency.

That's exactly what I was looking for, yes. Thank you, @Speve-O
Never knew about this!
