I don't have time to troubleshoot this for you but you might try using
the "strum" keyword in your blob statement. It might help solve this
problem for you though it will likely take longer to render.


This is a typical usage of the sturmian root solver which gives greater
mathematical accuracy when calculating the blob object -

blob {
    threshold .65
    sphere { <.5,0,0>, .8, 1 }
    sphere { <-.5,0,0>,.8, 1 }
    sturm
  }
