View Full Version : Strange C4d Rendering Engine
Dear friends,
I am surprised by my very basic scene...
Cinema 4d is liting the object (sphere) whish is behind the other object and not visible direclty from the light...
Have a look at the image and the scene which i have attached...

AutoLight is off.. still the sphere behind the box is litted.. and the light is very simple without any falloff...
Regards
JEet.

True, but then again Maxwell works with entirely different algorithms by default than 99% of the render engines out there.
In any raytracer or scanline renderer, light will travel straight through objects unless you activate shadowcasting.
If you use luminous geometry instead of a light, and render with GI in Cinema, you'll get closer to what you expect. But that will cost some rendertime instead.

Very true...
Actually i was trying to create a sub surface scatering object for a studio.. in which the main spot lights are getting diffused by a cloth (SSS material).... like a professional jewelry photographer does...

I see. Try a very big arealight, activate inverse square falloff, check the option 'show in reflection' - and if you need the soft diffused shadowing, enable areashadows as well. With some tweaking, that might get the look you're after.
.
For your help...
I will try for sure...
