V-Ray error: Fatal error clearing key frames.

[monsteradurm]

Hi,
We are getting this error frequently on scenes when using Phoenix to render some ocean scenes.

'Error in RenderTasks: V-Ray error: Fatal error clearing key frames.'

the std output is as follows:

If there could be any insight shed into this it would go a long way to helping with a very timely deadline shortly..

Hi,

which Phoenix version are you using? The V-Ray is 3.25.01 as I see. It's a quite old version. Is it possible to update V-Ray and try again or send us a scene to test it?

[monsteradurm]

Actually we are using Vray 3.404 - and it is definitely impossible to update towards the end of a project.

Hey,

Never seen such error so far - is it affected by Ocean Subdivs and memory usage in general? Is it random or happens always on certain frames with certain scenes? A scene would help the most with such kind of issues.

Cheers!
