When a render fails, it may exit with a code different than 0. This may be due to multiple reasons. The best thing to in such situation is to check the log produced by the chunk you just rendered. Alternatively, and more easy, right click on your node, and select Realtime Log->Enable and open. After opening the realtime log window for that machine, re-init and restart the render. The full log from Maya (are you talking about Maya-redshift right?) with be dumped in that window. feel free to copy and paste in response to this topic. Also I’m moving this topic to Muster 9 because you created it in Muster 5 forum.
