animated vrscene make vray crash

[dddjef]

This is a very specific bug but very annoying to us, since it prevents us to use network rendering.

We are trying deadline which distribute render by launching vray.exe on exported vrscene file. Everything runs fine, except when rendering scene with particles. (we got some mountains, and trees are done with particles). When a computer finish to render a frame, vray.exe crashes, an deadline hangs because it doesn't receive the "OK message" it expects. So the rendering stops

I've simplify the scene, you can make it crash when you hit render.
it won't crash anymore, if :
- you reduce the number of particles
- or if you reduce the number of exported frames (but the number of actual rendered frames doesn"t change anything)
-or if you delete the second material (the pink one) on the sphere. It is very strange, if I keep the slot, it crashes, I have to delete it.

Works perfectly for me, could anyone confirm?

I've test it with another PC, same configuration, but with blender 2.67.1. When the render is finished, it crashes too.

It crashes if you render frames after the 68th, where there is also a suspicious marker in the timeline
I see that this bug is present if you press esc before the end of the animation render (only if in the animation there is the 68th frame).

Re: animated vrscene make vray crash

I tried to delete markers, it still crashes.
You can try to render with a end at 65, it crashes too. It's dependent from the time segment length, not its absolute position
I tried to render by command line. If you export the entire segment, and then only render one frame by command line, it crashes at the end.

I feel there's something wrong inside the vrscene, this "thing" is dependent from the second material slot (matID 2) and it makes vray crash when it unloads memory at render end.
