UVW randomizer not working

Not sure if it’s latest vray updated related but for some reason this is not working here. Mapping channel is correct, the wall does have its own UVW map, not sure if that is necesary. Tried randomizing U and V offset by 100, 500…but everything’s the same. Map is of course in vraybitmap. Everything else is default.

Sorry my bad, you have to check stohastic to get it randomized on a single object? It’s working now.
