I bought a really great office model from http://www.iw43d.com/ and I want to make the ceiling lights realistic lights. However rather than find each light and add a light from vue eg a point light (as there are many many lights in this scene), I went to the materials editor and found a general material for all ceiling lights in the office. Is it possible to somehow make lights throughout the whole office just by changing the material. I messed around in the effects section with luminosity and glowing etc, but it didn't really seem to cast shadows or work well. I did have the cast shadows button in the effects ticked. I turned up the intensity to 1000% but that didn't help either. Love esther
