Hello guys ,

am learning renderman shading language, am trying to make a ghost
shader , but am having problem with opacity, basically I want my
shader to have transparency but only with other objects ( not with
itself), the problem is that a shader can't have two opacities it can
only be controlled by Oi what am trying to achieve here is that I want
my object only to blend with other objects ( like a ghost ) but I dont
see the faces inside itself.
can anybody help me ?
I can send images for my shader

Yes, it's always helpful if you post images, so we can see, what you
are trying to accomplish!

Hello again,

here is what am getting.

the point is I want my surface shader to have opacity, and blends with
other objects not with itself ( I want it to have opacity but doesnt
show its teeth for example, like a phantom), what am getting is that
it also blends with itself, how I can control opacity so it doesn't
show its inner/back faces like the image in the first link ?
