Hello,

i m new to Revit (and i have to use revit 2008 ),

i have a question: is there a possibility in light fixtures that i can turn off 'casting shadow' function of a particular light?

I am after a good ambient light source for internal scenes any sugestions??

if i place few internal lights, all of then cast shadows and it looks really artificially - and the shadows dont have soft edges...

(it is hard to get soft shadows in revit 2008 -  do you agree with me?) 

Otherwise an interior scene looks too dark ( and adjusting brightness dosent help).

Any suggestions from those expereinced ones?

Thx alot.

Getting good interior lighting renders in 2008 takes time and experimentation and you probably have to cheat a bit to get half realistic renders.  With respect to ambient light, I used to set some dim lights outside the view range of the camera (far away if possible so that the light has spread).  I don't have 2008 at the moment, but there is a soft shadows setting.  You also need to do a radiosity calculation.  Set the raytrace settings to best, increase the reflection bounces, set in soft shadows, blury reflections.  Of course this will substantially increase the render time, but reasonable results can be achieved.

Alternatively, get 2009 where the rendering resulas are subatantialy better.
