I have Maya 2011 on a 32 bit computer and have set up Mental Ray Satellite 3.8.1 slaves on three other 32 bit XP computers and that works fine.
I have installed the Mental Ray Satellite 3.8.1 for 64 bit on one of my 64 bit Windows 7 machines. When I add that computer to the maya.rayhosts file at the end it is extremely slow to connect. It seems like it is a network packet distrubution trouble of some sort? When MR finaly starts the distributed rendering the 64 bit machine does not contribute to the render at all. When the render is finished the master machine dies.
Is there a problem with DR from a 32 bits master to a 64 bits slave even though the MR satellite is of the same version?
