What are your material settings? They should be: Transparency 1.0000 Transparency_Edge 1.0000 Transparency_Falloff 0.0000 All other setting are irrelevant. Also check your transmap itself to make sure that the parts that are supposed to be tranparent are 100% black, ie red = 0, green = 0, blue = 0 Finally, is this the preview mode you are showing us, or is this the actual render? In preview mode you will see a faint image of the transparent item, but it won't be there when you render it.
