.. code-block:: glsl
CUSTOM.x = rand_from_seed(alt_seed1);
vec3 position = vec3(rand_from_seed(alt_seed2)*2.0-1.0,
rand_from_seed(alt_seed3)*2.0-1.0,
rand_from_seed(alt_seed4)*2.0-1.0);
vec3 position = vec3(rand_from_seed(alt_seed2) * 2.0 - 1.0,
rand_from_seed(alt_seed3) * 2.0 - 1.0,
rand_from_seed(alt_seed4) * 2.0 - 1.0);
Finally, assign ``position`` to ``TRANSFORM[3].xyz``, which is the part of the transform that holds
the position information.
.. code-block:: glsl
TRANSFORM[3].xyz = CUSTOM.xyz*20.0;
TRANSFORM[3].xyz = position * 20.0;
Remember, all this code so far goes inside the ``RESTART`` block.
