HELP! black dots or pixels in render?!?

[DPGrafik]

Hi,

I have a rather urgent problem, i'm working on an animation that i need to start rendering this week. I've decided to use a online farm which run on windows and or linux.
my own setup is OSX 10.9.5. both me and the farm are running Maya 2015 SP6 and VRay 3.0 the official build on the website released oct 20 - 2014.

Now when i render a still on my own machine, both with or without distributed rendering it renders without any problems at all.
As soon as i send the frame/scene to the renderfarm it sends back pictures with black dots or pixels in various places. Has anyone else experienced this?

I've tried clamping both in max ray intensity and color mapping. Adjusting the shader highlights and changeing bitdepth in the final image, but nothing helps.

The VRay GI setup is BF/LC i use a dome light and a rect light for key light. Everything in the scene besides the geo is rather simple.
Only the beauty layer is affected. If i have a zdepth, multimatte, ao or something that isn't affected by the black dots/pixels

Embree is on as well.

I've attached some examples

The black pixels do look weird. I would check on the shader weather fix dark edges is on?

Obviously if the normals are ok on the mesh? it could be something else, is there subdivision on the geo? could be that if you try turning it off.

Lastly, if you dont have a solution post this piece of geo here and some one will help you out!

This looks like a bug. It's probably already fixed, but it would be best to send that part of the scene to support@chaosgroup.com to confirm. If it's fixed, we'll get you a newer build.

Best regards,

sorry for the late reply - but the dots for whatever reason dissapeared, and havent' bothered me since. Weird to say the least... but i'll email the scene with all my specs if it turns up again
