DR some slaves buggy...

[Komposer]

Hy,

ive installed my abs new vray for max sp4 and RT!
One Master and 6 slaves.
On every machine i did the same procedure with servises (DR and RT).

All slaves works perfect with RT!

But 3 of 6 slaves makes probs with DR!
When I start the machines completely new, the first render works perfect with all!

When I change positions of objects - it works fine.

When I change light positions or the diffuse color, 3 off 6 slaves dont render the new color and the new light pos.
They renders, but with the old color - no update on any chanchings in scene.
(Looks like, that they didnt update their framebuffer or so.)

The mastermachine renders everytime perfect!

No materials and I did one backburner job first!

What could be the prob - any idea?

Thanks for help,
Jörg

additional infos...

in this moment, I saw the hint to log files on C:/

one Alert is in every logfile...

RT...

*** ALERT! Could not open INI file: "C:\Program Files\Chaos Group\V-Ray\RT for 3ds Max 2009 for x64\bin\VRayRTSpawner.ini". Using defaults.

DR..

*** ALERT! Could not open INI file: "C:\Program Files\Autodesk\3ds Max 2009\VRaySpawner.ini". Using defaults.

And right, I cant find any of both...

Are there any bitmaps in this scene?

(The missing .ini files are not a problem.)

thanks for answer Vlado,

no, there are no bitmaps - nothing special - a plane, a sphere, a rect vraylight.

But ive new results on testing it.

At first, ive done a new Backburnerjob again with all machines.
Then i tried first DR again.
And it works absolut perfect with all machines and every editing!
Then I checked RT again and it works absolut perfect with alll machines too!

Then I checked DR again....AND...
Buggy buckets comes back again..and nothing helps to repair it!

It seems so, that when I worked with RT - only then DR is defect!

And I think, that when prob is running, its more like "master didnt send scene correct" then slaves didnt work correct!
I mean that, because I increased AA massive and it renders so fast as before - but buggy (most of tiles werend updatet right).

On all slaves,I did "Register DR" and "Register RT"
Perhaps this was the wrong way to setup them?

it runs - but low CPU power on slaves..

after checking again installation guide and doing what there is written...
it runns perfect!
DR and RT parallel on all machines...

but what I see is, that RT cpu power is only 70% max on all slaves!

is there something to do, to optimise cpu power of slaves?

Best regards,
Jörg

You can try to use more samples per pixel (to 8, 16 or even 32), and/or to increase the ray bundle size to 128 or 256.
