Material using SphereMask not showing up in sequencer render

Hello,

I have a starter content material with the only change being this addition of a sphere mask to the opacity mask

Then I have a blueprint update the location of the texture so I can cut holes or “materialize” something

here is a gif of it working

I have a level sequence set up, when I go to render a video, the SphereMask is ignored and not applied at all, all the meshes are solid

I can’t get the “MaterializeVFX” free plugin to work, and I’m at a loss for other methods, any input would be greatly appreciated.

Cheers
