Refraction isn't affecting particle system in-game
My refraction emitter distorts the particle system when previewing in Cascade. However, when placed inside a level it seems to only distort everything that's not the particle system itself.

Try going in the material of the assets/particles you want to be affected by refraction (the material of those currently unaffected by refraction) look for the Separate translucency tab under translucency. If you uncheck this it should be affected by refraction of other effects. Keep in mind that no doubt this might/will cause other problems. But it does solve for me when my priority is the particles to be affected by refraction of other vfx.
Separate Translucency can be found left hand side in your material detail panel. (Click on empty space in your material) Under the translucency tab.

Try setting your refraction particle to Camera Facing? It works for me this way and it appears to be a bug that some particle Screen Alignments do not support refraction currently:

Depending on what version of the engine you are using you may be encountering an old bug. Try placing a static mesh in your level with the same VFX and put a refractive material on the mesh. If the particle renders with the mesh visible you are experiencing a bug that I thought was fixed in the most recent release of the engine.
