I only want the bottom half of my cape to simulate cloth.

If your cape is a skinned cloth (most probably, and if it is not it really should), simply set the skin radius and skin compliance of the particles you want to ignore simulation to zero, as described here:
http://obi.virtualmethodstudio.com/tutorials/skinconstraints.html

Also, this video should help you understand skin constraints:

If you're using a regular cloth (not recommended for characters), create a particle group containing the particles you want to attach, and then use a ObiParticleAttachment:

kind regards

Now I have reimported Obi cloth and also deleted everything for my character including scripts, mesh, and whatnot and also reimported that and then readded all the scripts recreated blueprint I get this error now.
how do I fix this?

so after removing the doubled sided mesh it started working again -_-

http://obi.virtualmethodstudio.com/tutorials/clothsetup.html

Two-sided cloth is generally easier, better and much more efficiently done using a shader.
