This is a furniture item (name =BronziQ8 Cloud Backgrund) that creates a transparent wall (full opacity layer for ultimate realism) to look like smoke, or fog. Created to give that "fog machine" look, this item is best used for still photo shoots and not intended for general chat. To use: Place item on a floor node (ideally - any furniture node will do). Resize and reposition as necessary. Ideally, this item will be placed fairly close to your avatar's standing/sitting node and the size/position adjusted until the smoke is in a good place for a picture. Please NOTE!!!!!!!!!!!!! IMVU currently has a bug where some clothing items - most notably some hair items and some necklaces - do NOT render at all when placed behind other transparent/translucent furniture items. If you've ever been in a room, rotating around and your avatar's hair suddenly disappeared, then you've seen the effect. There is NOTHING I can do about that. Hopefully IMVU will fix that bug one day. I've successfully used this product with many hairstyles, clothing items and such. So far, I've only come across some necklaces that "disappear" when viewed through this item. Your results may vary. Sample images: Standalone Cloud Background with a blue & Black background. Not that there are various levels of "blending" done - this item uses a highly detailed opacity map to achieve the wonderful Cloud Background .
