scale mesh emitter in blueprint

Hello, I was attempting to scale a mesh particle in Cascade and blueprint. I think I might be missing something obvious. I attempted to use an instance parameter in init scale, but that didn’t work so I tried to use the size scale module and the set vector parameter in blueprint, but I couldn’t get the mesh particle to change. Thanks in advance.

Update:
I attempted adding into the construction script to see if I needed to set the vector parameter there, but it didn’t change the emitter. hmmm
