Dynamic Parameter Expression doesn't seem to work with Beam Particles
I'm trying to make use of a Dynamic Parameter Expression in a particle system, in order to pass data to its material. I have set it up in pretty much the same way as the example here:
Everything seems to work fine while using standard particle sprites, but if I try to use a Beam type, the data just doesn't seem to get sent to the particle system.
I have tried various things but have drawn a blank. Does anyone know if this is a bug or if there is a way around it? I am running from source so I can make changes to the code if necessary, but I just need to get this working.

Just found a workaround for this. You have to do this: https://answers.unrealengine.com/questions/356404/parameter-material-module-in-cascade.html and then you can change material parameters of the particle material like you would do with any dynamic material.
