Chaos Corona for Cinema 4D => [C4D] I need help! => Topic started by: AntonCromas on 2022-08-06, 02:17:13

Hello,
Is there a spot light for corona? The directionality option in the lights doesn't do the trick, shadows lack sharpness.
Regards,
Anton

You can use native C4D spotlight.

Thanks for the reply.
I mean can you really say its supported when its a basic point light with no way to control softness of the shadow.
Seems like there is no way to get a basic photography spotlight like we use at the studio irl during the shoots, which is a huge downside since thats how our photographers add visual detail using gobos.
Only engine that doesnt have a spot light from what I have gathered =( Was just hoping there is a work around because we really like the material look and how softbox lights look.
Regards,
Anton

Using native lights, edge softness is controlled by Inner & Outer angle. Falloff, Gradient Colored Edge, Rad. Decay, Clipping... all help in defining shadow sharpness like with AR/Physical...
Oh, I see now none of shadows really work.. ?
BTW
To get sharp shadow w/ Corona's Area light, make it really small (just like IRL)
and for realism sake, best is to model casing/housing & put IES profile inside. This way you can get "perfectly correct" results.
-
Like Burnin said, do a tube and put a small area or object light in it with an IES and you'll get a perfect result

Do you have a reference image you're going for?
