Hi There,

Im getting a problem when clicking the IPR button to innitiate RT rendering. The console errors I get are these. Do you know what may be causing this to happen?

Im running Linux 64bit,
Maya version: 2011 (same happens on 2013)
vray version: 2.25.01-20121120

// Warning: [SettingsEXR] No image writer specified. //
// Warning: [SettingsTGA] No image writer specified. //
// Warning: [SettingsTIFF] No image writer specified. //
// Warning: [SettingsSGI] No image writer specified. //
// Warning: [SettingsJPEG] No image writer specified. //
// Warning: [SettingsPNG] No image writer specified. //
// Warning: Could not use any of the selected (0) hosts for distributed rendering! // <------this is odd as distributed rendering is turned off in the globals.

This terminal output is perhaps more useful...
The vray framebuffer just returns a black image and doesnt appear to render anything

IPR always works in DR mode, using a render server running on the same macine. V-Ray will attempt to automatically launch the render server, but sometimes this fails. Can you tell me whic OS you are using?

Best regards,
Vlado

[vlado]

Sorry, just saw it's Linux. In that case you can just try to run the slave manually.

Best regards,
Vlado

Thanks Vlado,
I got the renderslave server up and running but still I cant get RT to work correctly. The error im getting from the server console is this:

It seems using a newer build has fixed this. Thanks for the help Vlado.
