Anyone know how to fix this? Everytime I render it, the invibile materials leave those streaks. I thought if I changed the reflective material from white to black that would help. It didn't. "A" and "B" are in their normal state with white reflective. "C" has a black reflective.

It's the ambient color that should be black. The reflective color can be any color. :)

Make sure the transmap you are using is full black ... If it isnt it will not work .. a lot of times if it is almost black it will loook black to the eye .. That could be the problem

heya; and remember to set the edge falloff transparency thing to.... whatever makes the edges fully transparent, instead of less transparent than head-on things.

check the highlight color also it needs to be black

The lower the falloff, the more "transparent" the object is (I found out the hard way...:-)). And the Reflection value DOES matter if there is a map in the reflection channel; I had an image with everything else set "right" but with "ghost images" where the reflections would have been!
