Is it possible to create a dynamic material instance from bsp?

I would like to change the opacity of a material on bsp when my player character moves behind it. I know this is possible with static meshes but I have not been able to create/alter a dynamic material instance derived from bsp. Is this possible at all?

Thanks in advance.

BSP doesn’t allow me to use any material related functions in blueprints so I’d say it’s not possible with blueprints.

You can convert bsp to static mesh in the advanced tab of brush settings though.
