Big thanks for reporting it. Well, the "Fixed bug updating first frame rendered by a node on Backburner jobs (Mental Ray only)"
was exclusively mental ray related problem and up to now we don't have any similar V-Ray renderer issue reported.
Recently, we've added additional log options. To enable the log, please set General
- Log Level
in any of Forest objects in your scene, before sending it to renderer. The log fine is located at:
C:\Users\<user name>\AppData\Local\Autodesk\3dsmax\<max version>\ENU\Network\Max.log
Would you mind to send us the log file for the node which don't render correctly? Ideally, please try to reproduce the problem with a minimal scene and send us
such scene to check it here. Thanks a lot for your collaboration, your feedback is very important to us.
