Topic: How can I have both 1.09.03* and 1.46.** installed at the same time?

VRay requires several files to be at the max root, so managing which version of VRay is active through plugin.ini does not work. The way to install multiple copies, for instance installing the 1.46.** beta without losing the 1.09.03 version of VRay, is the following:

  1. Make a copy of your 3ds max installation directory, call it something like 3dsmax6_VRay1.46. The copy will run fine without needing extra authorization as long as it is on the same computer.
  2. Delete the old vray files from the new max root and plugins dir. These files typically start with Vr or VRay. Like VRay60.dll (50 if you use max5), VRender60.dll.
  3. Edit the plugin.ini file in the new max dir so that the path to the 3ds max copy is correct.
  4. Install VRay 1.46.** in the new max dir.
  5. Start the new max copy to use the new VRay, use the old max copy to use the old VRay
