how do you make something clear like glass not as good though i just need to make one part see through can anyone help me?
set Spec, Hard, Sp Tr all to max, set alpha to 0 or maybe up to 50 unless you want it completely invisible. Push the ZTransp.
If you want to set a part of a mesh transparent, look at this simple tute that shows you how to have different textures on the same mesh:
In any case remember Blender’s not a raytraces, so you will never get the correct appearance of glass, and to come even slightly close you must be VERY good at tweaking materials.
