UPDATE: Unable to persist changes when Node 0 is launched in nDisplay and connected via multi user session

[Olav_Verhoeven]

Hi,

When our project (node 0) is Launched in Ndisplay onto our Ledwall, we can connect to the multi user server, also the connection with revision control is fine.

But, the moment we would like to persist the changes we get following error: Failed to copy file. from the temp multi user server folder to our local project folder.

When we disconnect the Node 0 persisting to local project or revision control is fine.

Clearly the node 0 is conflicting with the editor or multi user server.

Any thought on how to fix?

Did you check file permission? Most revision controls set everything to readonly.

Did you start from the same version of the project into multi user? Or did you open the project on that node?

Try to delete the saved folder on the node then…

Hi,

Yes file permission is ok.
I did started with same version.

Worth mentioning: I only have it when I try to persist on the same computer as the node, when running on another PC, all works.

So you have one instance of nDisplay and one instance of the Editor running on the same machine from the same project folder?

I would imagine those files are locked so they can’t be overwritten since it is probably considered “open” in the other instance of UE. If you close the nDisplay node does it work?

[Olav_Verhoeven]

Hi, Yes than it works.

[comlys (Shaun Comly)]

Then this is a Windows file management issue, which we unfortunately do not have control over.

Both instances of Unreal (nDisplay render and Editor) try to write to the same files if you try to persist the MU session.

Try to copy the project to another folder and run you nDisplay node from there. Per5sisting via the editor should work now.
