I try to use the UNC path but i don't get it. How does it work? Can i simply create a shared folder in "My Documents" called "itoo3" and then in the 3dsmax.ini file write : Dir27=\\itoo3\maps\
The itoo3 folder has the same name for sharing (itoo3)
No, "itoo3" is the remote computer name (here it's only an example), and "maps" is the shared resource. As instance, if you share the folder "maps" in the computer "server1" the UNC must be \\server1\maps. If the textures are located in a folder below the "maps" sharing, it must be appended to the path: \\server1\maps\stones
Isn't it strange that network rendering problems come from missing textures? Because in the viewport of 3dsmax2010, i can see all my trees with textures...
We have succesfully rendered your max file in our network, so there do not seem to be any problem with the scene.
Since the workstation renders the scene locally, but fails with Backburner, all point to some problem with the configuration used when Max is launched from Backburner. Most of these problems are related with missing plugins or textures.
Are you running Backburner Server as service or as application ? Running as service, it would be using a different user account... and therefore not using the same 3dsmax.ini file that when Max is used interactively.
We really need the Backburner logs to know what is the problem. Could be possible to get a screenshot of Backburner Server showing the error ?
