hi all just a small problem, will probably be able to be fixed quickly no doubt i'm being a noob :D

i am creating light shelves and trying to show how it will reflect the sun up onto the ceiling. 

to create the light shelf i created a roof and made a new type with just a finish material (thickness of 50mm) and offset it by 2500mm from the floor level leaving approx 800mm between the shelf and the underside of the floor slab.  the material i used was Aluminum\Polished,Plain with a shine value of 128 (maximum?).

 

but when i tested it out by enabling shadows there was no light reflected to the underside of the floor soffit!

so i tried accurender both internally and externally but still no luck!

 

the light shelf does cast a shadow inside the building, i just need the sun rays to bounce off the shelf onto the underside of the upper floor slab, any suggestions plz?!

 

i'm using revit to try and see the advantages of using light shelfs in my building

Read up on radiosity.  The help screen does give you this warning

 Radiosity is a powerful technique for calculating INDIRECT LIGHTING and performingLIGHTING ANALYSIS.  When used properly, in conjunction with ray tracing, this technique can produce images which contain more subtle illumination effects than those produced using traditional ray tracing only.Radiosity is generally most useful for SMALL ARCHITECTURAL INTERIORS.   Use of thisoption WILL require more memory and processing time.  These additional requirements willbe sensitive to the size and complexity of the model.  Radiosity is usually NOT appropriate for the following situations:  *  Non-architectural models  *  Large or complex models  *  Exterior renderings
