Working with Max 9 x64, rev3 and vray 1.50.00.
There’s a known Max-bug regarding the PArray Rate not working, but having some other trouble with it as well.
1. Sometimes when the PArray isn’t shown in the viewport due to complex scene or redraw-issues, then it won’t render either.
2. The Viewport display percentage affects the render, ie if set to display 10% it will only render 10% as well…
3. And finally, when using DR the PArray’s won’t be rendered by the nodes, only by the host.
Anyone know a solution or workaround?
EDIT: When tried to recreate this in a new scene, i only imported the PArray’s and the base geometry for particles and emitters, i had none of the above mentioned problems… so i guess it seems to have to do with no.1 - complex scenes
Same problem still: DR nodes not rendering the PArrays.
It seems only to happen with bigger scenes and PArrays with high numbers.
Using hedges with 55000-60000 instanced leafs as particles.
Rendering without DR works fine.
Workstation: Max 2008 x64, Vray 1.5 SP2, Win Server 2003 Standard x64 SP2
Node1: Max 2008 x64, Vray 1.5 SP2, Vista Ultimate x64
Node2: Max 2008 x64, Vray 1.5 SP2, XP Pro x64
It’s not network-path related, all maps work fine and enabled missing maps check.
I suspect it’s a Max bug, since in some cases the viewport stops displaying the PARRAY previews, when numbers are between 55000-64000(maximum). Ofcourse without any viewport degradation enabled.
Chopping up the hedges in smaller volumes and using less particles per volume seems a way to work around it, but a real solution would be very welcome.
If you take a look at the vraylog.txt file on the render slaves, what kind of info does it say about the PArray objects? Are the any warnings and such?
No errors in log, only these lines mentioning the PArray’s:

I am rendering frame 0003, single frame. The PArray’s are set at speed 0, life 100
Note that almost all other geometry has a validity , except (on quick glance) the PArray’s and RPC’s: [480, 480].
Still having trouble with PArray in Vray, nodes don’t render it.
Also, the settings for ‘Viewport Display: Percentage of particles’ determines the amount of particles rendered as well. When set to 10%, only 10% will be rendered, and still, only by the workstation, the nodes render blank.
