Backburner Renders

This question has probably been asked a million times, but to get the computers to render on backburner, do I need to add an additional Vray license node??

Once I have the extra license, is it a case of logging into chaos group under the same account?

Error on backburner:
2022/02/09 15:33:13 ERR Error message: 3dsmax adapter error : Autodesk 24.0 reported error: [V-Ray] Could not obtain a license (-7): -7: The ChaosGroup License Server is denying access. Update the license server and check access filter (if any).

You need a VRay render node license for EACH computer that will render, no matter if its CPU or GPU
