VRay DBR won't start

The issue here is that as you are using the “3dsCmd” plugin in Deadline and NOT the “3dsmax” plugin, then you need to make sure that you have enabled: “Dynamic Start” in the “3dsCmd” plugin configuration. Your Slave logs show this line, showing it is currently disabled (by default):

Go to here: docs.thinkboxsoftware.com/produ … figuration

and scroll down until you get to this setting:

V-Ray DBR Off-Load Rendering
Dynamic Start: If enabled, a V-Ray DBR off-load job will start rendering immediately after TaskId=0 (master machine) has started rendering. With V-Ray v3.2 (min SP2) onwards, slaves dequeuing tasks of this job will start participating in the ongoing render when V-Ray re-scans it’s *.cfg file on the master machine. Default: False.

and set it to TRUE.

Additionally, as you only have 2 x Deadline Slaves, there is little point in sending a DBR job with more than 2 x tasks in total, as the first task will be the MASTER and the 2nd task will be your spare slave machine. Any other additional tasks will not be used.
