Black Frames in Animation

[worldmode]

Hi, we have a big problem with an animation. Randomly the frames are black with the light, very strange. Camera clipping is on...

,



Randomly the rendering is correct, can you help us please. Thanks a lot!

right click on the black pixel, what does it say? NAN/IND, or 0?

[worldmode]

here is a screenshot with right click. Hope i understand correct?

[Ondra]

yes. So this never happens on single machine? Only when using BB?

[worldmode]

Single machine and backburner. Thats the main problem, because so is local rendering unfortunately not an option.

[Ondra]

ok, can you share the scene? http://corona-renderer.com/upload

[worldmode]

Thanks a lot for watching it. It can take some minutes, sorry. 480 MB, zipped. ;-)

[worldmode]

now the file is in the Debugging Drop box. Thank you!

[worldmode]

any ideas? my workflow at the moment is... restart the server and hope it is rendering right.

"Mittelweg_cam23.zip" - is this the file?

[worldmode]

yes. ;-)

ok, newest daily build has some additional safety checks that eliminate one problem I found in the scene. Can you test it to see if it no longer happens?

[Ondra]

Inactive topic, I assume it does not happen in latest daily as there were several new safety measures against similar situations

Wouldn't be too quick to close it, watching the said finished animation I see a lot of stuttering, which happens when frames are missing. So perhaps his solution could have simply been to delete the black frames in meantime.
