Is there a way to make my avatar's primary texture a complete invisible texture that others can see without using a special shader? As in, my avatar is fully just see through with nothing visible? 

The reason why I don't want to use a special shader is if my avatar is perf-blocked I still want the default look to be invisible, though my name tag will still be visible obviously. Going with an "invisible man" (girl) concept where all I have are a hat and clothes walking around while my entire body texture is invisible. However if I use a special shader to do this, and someone has shaders blocked, it will make me just a generic color walking around which ruins the effect
