DR and Displacement

[CliveG]

I am getting repeated failures in a distributed rendering.

 

It only occurs when Displacement is enabled in the Vray Global switches.

 

If Displacement is enabled but all mat's with displacement have the displacement switched off, it still occurs.

 

It's an interior scene (with Vray sun sky and a couple of windows contributing to the IES and plane lighting) and generally I'm just trying to displace carpet.

 

It affects the entire scene, somewhat like I'd imagine would occur with the reduction in light bounced by the roughened surface of the carpet. So my walls and furniture and everything renders darker (in some buckets significantly darker) on the DR node than on the main DR host.

 

And can I just be clear... the DR node definitely - DEFINITELY - has access to all of the displacement files.

 

I know the obvious answer is it can't locate a file.... but then why does it do it if the displacement is switched off in the material but displacement still enabled in Global Switches.

 

I'll grant you that there's an outside chance that the DR node is failing to locate some other file, but why does it render perfectly with Displacement switched off in Global Settings then?

 

I've tried some empirical testing, but would love a silver bullet from one of you Vray Guns out there, as I think it'll take forever otherwise!

 

I should add that this occurs in all of my scenes nowadays, it isn't one rogue file.

 

I don't get it....

instead of using DR, have you tried submittiing the scene to the node as a backburner job to only the problem system just as a troubleshooting measure?

2nd step would be submitting as a backburner job to the render node with DR enabled and your main system selected as a DR node to see what happens
