Change material flow direction Niagara ?

Hi there.

I have made a material to use with the ribbon renderer in Niagara and that works great. Now I have added another particle block ( not sure what to call the main niagara unit with all the settings ) and I set that to Mesh Renderer.
The material is flowing in the wrong direction.

I have seen many people suggest using a custom rotate node, but all my textures have stuff plugged into the UVs like panners and masks and when i try to put that setup anywhere it just breaks everything.
Short of having to go back to my source materials in photoshop and then recreate all my flipbooks at a different angle, is there any easy way to just change the flow direction of an entire material in Niagara ? So that, for example, it’s flowing down the mesh instead of accross ?
It seems like it should be such a simple thing but I am banging my head against a wall now.

Any help would be much appreciated ! Thanks :slight_smile:
