I had tried this method yesterday, but didn't achieve result I was looked.
Differents between two .xcrysden scripts are in line:

array set mode3D   {space Off sticks On pipe Off balls On}

And there is my script:

#####################################

   scripting::open --xsf $env(HOME)/work/wf/NiO/afm8/animation/in.xsf
   scripting::lighting On
   scripting::display on coordinate-system

   scripting::displayMode3D Stick
   array set mode3D   {space Off sticks Off pipe Off balls Off}

   scripting::zoom +0.02 5

   scripting::scalarField3D::load

   scripting::makeMovie::init \
    -movieformat mpeg \
    -dir         tmp \
    -frameformat PPM \
    -firstframe  10 \
    -lastframe   10 \
    -delay       0 \
    -save_to_file out.mpeg

    scripting::makeMovie::begin

    wm withdraw .iso

    scripting::zoom +1 1

    set il 9.5
    repeat {50} {
	scripting::scalarField3D::configure \
        -isosurface           1 \
        -interpolation_degree 2 \
        -isolevel             $il \
	-plusminus 0

     scripting::scalarField3D::render
     scripting::rotate x +3 1
     scripting::rotate y +3 1
     set il [expr $il-0.02]
     scripting::makeMovie::makeFrame
    }

   scripting::makeMovie::end

########################

But, sticks are still on!

Could you help me?
