Hi, I am doing a fur test. The fur mesh/character has about 0.5 million polygon faces. The fur mesh is attached with VrayFur, 5 fur per face. I assume the fur number is about 2.5 million-ish. VrayMtlHair3 is assigned to the fur mesh. It takes about 8 minutes to rendered at 1k with BF+LC and NO Mob…

i will re-create the scene on another machine to see if the scene is corrupted.

Hello there, I manage to reproduce your issue - it appears if I have lower value for Dynamic Memory Limit(DML). Once Vray reaches the amount of RAM specified in Dynamic Memory Limit - and Maya freezes and the render stops. Here are two examples: Here I have set DML to 10GB - and render stops at …

Hey Svetlozar, Thanks for doing the test. I have 32GB of RAM. In the production scene, I set DML to 28GB. Maya actually takes less than 10GB of memory when rendering. Anyway, with LC and moblur, the LC phase took more than 15mins and crawling really slow after 90% (still going). If I switch to BF+B…

Still can’t reproduce this here. Btw what hardware are you rendering on (i.e. how many processors and what kind)? Best regards, Vlado

Render tests have been done on machines locally and on the farm with different specs. Sometimes the render hangs; sometimes it finished with much longer render time than using BF+BF. Maybe it has to do with hardware issues internally, but we can’t point our finger to something specifically at the mo…

Does it always hang with the Zumo drive message? Best regards, Vlado

[image] In late but here slight_smile Does it always hang with the Zumo drive message? On couple boxes I have tested locally, yes. It appears in Maya output window with VRay Log level set to “all messages”. I can’t say that for rendering on the farm though. I thought it has to do with accessi…

[image] VRay SDK (download link for kit and samples) On couple boxes I have tested locally, yes. It appears in Maya output window with VRay Log level set to “all messages”. I can’t say that for rendering on the farm though. I thought it has to do with accessing/saving LC files, but I got the sam…

AFAIK, there is nothing called Zumo in our infrastructure. BTW, I got this looping before Zumo is running thing with BF+BF too and the render finishes normally.

[image] Sound tip needed: shooting speech with DSLR right next to aircon condenser AFAIK, there is nothing called Zumo in our infrastructure. Then were does it come from? It’s not a part of V-Ray for sure… Best regards, Vlado

Ok, so what happens if you disable or uninstall that Zumo stuff?

Best regards,
Vlado
