VRayUVRandomizer - change in pattern when converting geo to VrayProxies

[Kelv]

I have a material which is using a VRayUVRandomizer in the bump channel, via a Vray Bitmap (in 'Mapping Source').
When I have converted all the geometry in the scene to Vrayproxies, I'm not getting the same pattern rendered before creating the proxies.

I'm not sure whether its due to the randomize settings (see below).



Is there a way I can get the VrayProxy and the non vray proxy pattern to match on render?
I have tried to merge the affected geos with the material back into the scene (no proxied), but still get the same issue.

Hope that makes sense.

The proxies most likely have a different naming (and the differences come from the By Name randomization). If you rename them to the name prior export the results should be identical. If you haven't done any manual renaming of the proxies (so their names are i.e VRayProxy_Sphere001), you can use this simple script to remove the first 10 characters:

select (for o in $* where classof o == VRayProxy collect o)
for each in selection do (
newName = replace each.name 1 10 ""
each.name = newName
)​
