Thread Subject: light & transparency problem

Hi, I have a problem to get some surfaces transparent, but
not shine with light, combined with objects that gets light
but have no transparency. Below is my code:

figure(1), clf reset;
[XX,YY,ZZ]=sphere(15);
surf(3+1*XX,4.5+1*YY,1*ZZ);shading interp;hold on;
surf(6+1*XX,4.5+1*YY,1*ZZ-1);shading interp
lighting phong;light;

[X,Y]=meshgrid([0 9],[0 9]);Z=0*X;
hnd=surf(X,Y,Z);shading interp
alpha(hnd,0.7)
axis equal;axis tight;

This looks awful, everything turns white more or less. Is
there some kind of handle to light, or how should I do?

I want the spheres with light & non transparent. The plane
should be transparent and have no light on it. Any idea? Any
help appreciated.

I don't see every thing turn to white.

hLight = light; % returns handle to light object

This turns off lighting on the surface:
set(hnd, 'Facelighting', 'none')
