Turn off Shadow for Trees

Corona Corona for Cinema 4D General

Hi,

I have some trees in my scene but I don’t want them to cast any shadows.

I tried to use the compositing tag and disable the “cast shadow” option - but nothing happens (bug?)
Then I turned off “Seen by GI”. In this case the shadows are gone BUT the Trees look like sh… Very wasehed out.

Any way to have Trees without casting shadows?

Thanks

I’m not familiar with C4D, but you are not supposed to use options outside the Corona engine to change what happens within in regards to lighting. The engine is physically based and expects physically correct properties.

The correct workflow is using the CoronaRayswitchMaterial.
You want to the ray switcher to connect the tree material to all channels, exept GI override. The tree will receive GI and lighting but not cast a shadow.
I hope c4d has the rayswitcher mtl.

AFAIK there is no shadowcatcher material in C4D yet. We will need to wait for this a bit.

@sht
Yup, found that “bug” also… am too, using disabled GI
“washed” are because there are no shadows, neither self-shadows… would be nice if these parameters would be implemented when it comes around

…oh, maru, hi
OK, understandable
so the things are intertwined, connected, tnx

Thanks mate,

the rayswitcher is not very well implemented in C4D atm.
If I do as described there still is no gi and shadow on the tree itself.

Maybe in the next alpha :slight_smile:

Not a C4D user, but in Corona “cast shadow” and “recieve shadow” are connected. You can’t disable one without disabling the other.
