Moving Spines

Here's a nice little piece of eye candy that
you can add to a map to give it that H.R. Giger
look .  A  nice  touch  from  id.

Start   out   with  a  basic  brush  as  pictured below.  Go up to
the  curves  option  on the toolbar and select cylinder.  Now
manipulate  the  brush/patch  so  that it twists and turns so
that an organic effect takes place.  For help with doing this
go  to  my  'bending columns'  tutorial  to change the object
so  that  it  looks  appropriate   here.


   

Once  the cylinder is shaped to your liking simply go to the
'gothic_block'     folder  in  the  textures  menu  and  use  the
'gkcspinemove' shader to cover your new patch. There  are
two  shaders  in  this  folder  that  use  the  same  texture  so
make sure your using the right one.  Now hit 'ctrl+n' so that
the texture is lined up properly with the patch.

    

Rotate  the  texture  on  the  patch  so  that  the  spines run
the length of the object.  Do this by hitting 'shift+page up'.
That's it!  Save, compile, and launch the game.
