Hi,
I find it a problem about the intensity of the lights. usually in vray it imposed a value in lumens, and that value remains fixed regardless of the size of the light, and rightly so. In corona it is not so, if you keep a multiplier 50 in a 5x5 cm light, that value distinctly different in a 100x100 cm light.
This is critical to have a proper scale and proportion of the light intensity and it is important to have a realistic result of the scene

In Corona, you must to use Lumen too, and not the default units.
-
It is right Cecofuli, but in cinema 4d is not yet possible because it is not the function lumens but only multiplier

Oh, sorry, didn't see it was Cinema ^__^
You cannot do nothing. You must to wait for lumen parameter =)

I hope that the team Corona add this parameter in cinema 4d

You can create an object and add it a Corona light shader, where you can adjust the intensity of a light. It's pretty like using mesh light in Arnold.

Hi, the intensity parameter specifies differential radiance per meter and steradian, so of course it scales with a larger light. Right now, Corona for C4D allows you to set the light intensity in photometric units like candela, lumen or lux and these should behave correcty with scaling.
