Title: DR fails to download scene (randomly, on/off)
Post by: Juraj on 2016-07-06, 20:41:29

Well, here's DR issue that I keep getting for long time, but finally decided to look into logs what is behind.

The DR fails to download the scene:

Code: [Select]

2016-07-06 20:28:18   Downloading 3ds max 2016 scene to render with 3ds max 2016
2016-07-06 20:29:03   Downloaded scene: 0 bytes in 44 s
It download some half-scene. Instead. Happens randomly, during same scene. The other node will download it sucessfully and start running.
What happens after is simple:

Code: [Select]

06.07.2016 20:29:32;  File Open Failed: C:\Users\juraj\AppData\Local\CoronaRenderer\DrData\received_scene_3332386331.max
06.07.2016 20:29:32;  Error loading file C:\Users\juraj\AppData\Local\CoronaRenderer\DrData\received_scene_3332386331.max
06.07.2016 20:29:32;  Error rendering frame 0: Unknown error while loading application
06.07.2016 20:29:32;  Send End of Job command to Max
I pondered upon this for long time, tried various stuff from help-desk, but nothing.

Seems like it might do something with network ? But what ? And why it happens on random basis when my network setup is always the same, unchanging.

Simple restart solves this usually btw. But then after 3-4 DR renders, it will do again.


Other issue that happens at same time: "A unexpected exception on network renderer". What's that ? Again, random, previous DR (still same scene) it would open. Will check if I have SP3 on all nodes, would suck if this is Autodesk again...
Using DR is like playing russian roulette : /

Why do nodes take so much more time transforming vertices ? Often like hanging for 5 minutes before they start moving the progress bar. 5 seconds (WS) becomes 5 minutes on way more powerful PCs.
They just freeze there, at 1perc. cpu usage.

Sorry, it was  beyond my imagination that you have no bugtracker account. It´s a report like yours (sporadically no donwloaded scene) and Ondra mentioned that that atm DR code gets rewritten anyway. Don´t know when there will be some initial release though.

Good Luck

honestly it will be best to wait about 2 weeks until we roll out next DR prototype with improved network protocol, than trying to fix the old version ;)

Same here. Right now 10 to 15% of the slaves fail in every DR session.

Good Luck
