Please how can i render with prman directly in mplay?, i follow the tutorial at the odforce.net (prman setup) everything is ok, i hit render from the output node and its work property, but if i want to render directly on mplay, i have to install one of the plug ins that come with proto_install command, after that when i hit render again it display a c++ error and in the houdini console it shows

“D04001 {WARNING} DspyName couldn't find requested driver C/DOCUME~1/NECROB~1/RI_SHA~1/d_houdini.dll (No se puede encontrar el módulo especificado.)
R90011 {SEVERE} Can't open display image ip”

How can i do? please help me!!!!

Thanks.
