octane textures & animated vertex maps

[armspan]

Hi! I'm having trouble getting octane textures to update when using a changing vertex map & wondered if there's something simple I'm missing.
I used the search function & found this: viewtopic.php?f=30&t=62669 but 'all objects movable' is already on & isn't solving the problem
Atm I'm just using it in the diffuse channel via the node editor for ease of monitoring but the intention is to use it (inverted) on roughness of a glossy material to simulate the trails raindrops leave on a window.

The vertex map is being driven from an x particles wetmap if that makes any difference.

and an example render that shows the mismatch between the current state of that vertex map & what octane is drawing from


Any help is very much appreciated, thank you!
