In my earlier post (see link) I showed the effects of using just a white tile, or a simple gray tile. I arrived at the mild gray with a softer gray center as being a good source of indoor lighting for Poser figures using IBL. It just depends on what you want to use IBL (Image Based Lighting) for- lighting houses, cars or people, etc. In my experiments- nothing beats HDR for realistic looking cars and houses- because HDR contains the closest effect to natural atmospheric sunlight- (HDR= HIGH Dynamic Range). But LDR (like grey-scales) are really good to simulate indoor lighting- and work especially well on Poser figures and prevents skintone "wash-out"- (a problem with HDR). So- in your Vue 5 IBL arsenal of lighting effects- you really need BOTH-- LDR and HDR to cover all your bases...
