Override the material and set the material colour mode to
PFMTL_CMODE_OFF using pfMtlColorMode, it's probably safest to set
this mode before applying the material but it may not be required.
(I hope this mode exists in pf1.2). It sounds like you only want
a material with EMISSIVE properties.

Angus.
