3dsmax adapter error - problems when using Autodesk Backburner

This article contains a possible solution for:

  • 3ds Max crashing when using Backburner and a high amount (200 or more) of passes is reached
  • 3ds Max freezes when zooming in and out in Corona VFB
  • Other symptoms include: "3dsmax adapter error", "timed out executing command", "Adapter returned unexpected code", "3dsmax.exe process no response", "Unknown error"

Possible solution: disable or uninstall your current antivirus / firewall software. We have received a report where the problem disappeared only after uninstalling the antivirus software, even though all applications required for rendering seemed to be allowed to communicate.
