you have to connect mia_material in the shadow and photon shader slot of the
shading group node - have you done that?

no i havent!

so just in the main shader group?

im looking and i cant find those nodes, are they just in the SG tab in the hypershade?

i hope it isnt my maya bugging out

yes it is in the SG. when you graph the shader network and view its input and output connections you will see the SG node. Click on it and view it in the attribute editor. Click on the Mental Ray tab and vwoila! You will see the custom shaders tab that includes the "Shadow Shader and Photon Shader." Middle mouse click and drag & drop.

This is where to find what q vask was saying, I do not know if this will solve your problem. Goodluck :)
