Urgent diag on error, log included

[MartinB]

We're rendering some hair with Yeti, its a 400 frame animation and we have 20 random frames that consistently crash on rendering, tried them on different machines on the farm and it doesn't seem to make a difference.

Can anyone make sense of the log error. It does the light cache pre-pass then crashes when it starts the actual render. The Warning: Invalid Geo is in the logs for the frames that render fine so don't think its that...

Thanks for any help!

Get a newer nightly/stable version of V-Ray and it will be fine.

Best regards,

Giving that a go with a nightly from 04/26, and just installing the one from last night.

The crash log above was with a build from March 17th

[MartinB]

The 04/26 version worked.

Cheers vlado

Actually I think I spoke to soon, most of the problem frames rendered, but still have 4 or 5 that refuse the complete with the same error.

[vlado]

In that case I will need a way (scene?) to reproduce this here.

Best regards,
Vlado

Hi Vlado,

Is it ok to send a scene that uses yeti?

Cheers,

Nathan

[vlado]

Yes...

Best regards,
Vlado
