Corona Compositing

[Mischa Portmann]

Hi Everyone

In Cinema4D in the Corona Compositing Tag I have the option to uncheck "Cast Shadows" but I was wondering if there's a possibility to do the same for "Receive Shadows" as in the Cinema 4D Compositing Tag?
Anyone knows a solution for this one?

Many thanks in advance.

With Corona's emphasis on being physically realistic, there is no option to turn off receiving shadows. The only way I can think of doing it would be in post, by rendering a Shadows and an ID multipass. The Shadows pass in Corona actually removes shadows if you add it over the beauty in post, so you could use the ID pass as a mask when overlaying the Shadows pass, which should then give you the object with no shadows (never tried it, but as far as I can think of, that would work).

I thought of that too... my problem is that I have a shadow on an object which is also seen in the reflection on the windows which can't be removed in post production... I used a plane with the texture of a frame out of a sequence to produce the actual reflection of the environment but the shadow that is cast by the building is now on that plane too because it needs to be quite close to the windows so I would only have to remove the shadow from the "background" object that is used to creat the reflection...

You could try putting your image for the plane into the self illumination channel instead of diffuse and keep the intensity low. That might cancel out the shadow (though it might be too bright then).

Also, look to loading the image in Corona render settings into the background override instead of a plane, but honestly. I haven't played with those functions yet.
