[Closed] Why don't user properties save when rendering over a network?

This is exhibited in VRay when changing the vrayproperties of an xref and then rendering over a network:

To replicate:

1. create a new scene and xref a box in
2. Script traversing the xrefs in the file and modifying the userproperties of

execute this script

fn setXRefScenesToMatte = (
    if (local xrefCount = xrefs.getXRefFileCount()) != 0 then (
        for i = 1 to xrefCount do (     -- get each xref scene in the file
            local xrscene = xrefs.getXRefFile i    -- xrscene equals the xref scene in which is loaded
            
            for x in (xrscene.tree.children) do (    -- for each object in the xref scene
                try (
                    setUserProp x "VRay_Matte_Enable" true    -- sets the object to a matte object
                    setUserProp x "VRay_Matte_Alpha" -1    -- sets the alpha contribution to -1, consider using 0 as well
                ) catch ()
            )    -- end each object in scene
        )    -- end all xrefs done
        true
    ) else false
)

fn resetXRefScenes = (
    if (local xrefCount = xrefs.getXRefFileCount()) != 0 then (
        for i = 1 to xrefCount do (     -- get each xref scene in the file
            local xrscene = xrefs.getXRefFile i    -- xrscene equals the xref scene in which is loaded
            
            for x in (xrscene.tree.children) do (    -- for each object in the xref scene
                try (
                    setUserProp x "VRay_Matte_Enable" false    -- sets the object NOT to a matte object
                    setUserProp x "VRay_Matte_Alpha" 1    -- sets the alpha contribution to 1
                ) catch ()
            )    -- end each object in scene
        )    -- end all xrefs done    
        true
    ) else false
)

3. execute this in the listener

setXRefScenesToMatte()

4. Do a test render, the object is correctly matted !!!
   (I am setting all xref objects to matte by traversing the xref files and navigating xrefScene.tree.children and setting the vrayproperty “VRay_Matte_Enable” to “on”)

5. Network submit this render and your render will be completely unmatted.

I am going to try registering a callback to matte them at #preRenderFrame but I haven’t tested it thoroughly. Any ideas why this information isn’t saved over the network?

Thank you,
