Find Two Material instance : "MI_MagicOrb_2D_UI_HP" and "MI_MagicOrb_2D_UI_MP"
This two can be putted into Brush of image in the widget as UI VFX and Tweak Parameter "_Height" to do Liquid animation
"NS_Orb_2D_BillboardPotion" is also a 2D VFX but allow you put it in 3D Scene as a BillBoard VFX(Maybe put it above head of NPC)
For 9 True 3D VFX :
Tweak Parameter "_NormalizedHeight" in Niagara System to do Liquid animation.
If U do not this Liquid-fill Feature and just want to use it as a Ball.Try to uncheck parameter:"Lid_Enable" to get desirable result.and is optimal to turn on "NoWaveAnimation" in the material instance of Cap.see Video at 4:50 and 5:40
One of them has special feature is "NS_Orb_3D_FlaskPoison".It can apply custom mesh-shape instead of Sphere-Shape.When U do this please uncheck parameter:"Lid_Enable" to ger desirable result.
the Seamless feature of "NS_Orb_3D_FlaskPoison" make itself being suit to afford this specific task .others (rest of 8) just cant do this well enough.. they are designed for Sphere-Shape.
Tryto find a material collection called "MPC_OrbGlobalHeight".U can Tweak these parameter to do Liquid animation as well.but more smoothly in runtime.just burry in mind.These are Global Parameter and Effect any instance of VFX.
Finally.Its Worth to mention that its possible to use True 3D VFX in the UI.Pls Search "Niagara UI Renderer" in the Marketplace.Its free plugin.If U find Cap Material is Gone in UI.Pls Turn on the "CapUseOldMode" in the Cap Material .THX~
