Nimesh,

For opaque surfaces the absorptivity is 1 - reflectivity.

For transparent objects, the incoming light is partially reflected, partially absorbed, and partially transmitted through. The total for each of those equals the whole...reflectivity + absorptivity + transmissivity = 1. For opaque objects transmissivity is zero, so you get absorptivity = 1 - reflectivity.

Dear Friends,

I want to change interior floor reflectivity of the building model in the eQuest. To do this I am opting to detailed edit model and going to " EL1IFLr Construction " but there shows ext. colour ( abs).

So my question is - How we can change interior floor reflectivity of the building model in the eQuest?

Can you please guide me?

Thanks,
