7-Band EQ - FilterDisplay not updating visually from script (SVF EQ + scriptnode)

the red_1

Hi everyone,
I'm building a 7-band EQ plugin in HISE 4.1.0 and I can't figure out how to get the FilterDisplay to update visually when controlling it from script.
My setup:

7 SVF EQ nodes inside a Script FX1 (DSP Network/scriptnode)
7 Parametric EQ effects in the FX chain (ParamEQ_LC, ParamEQ_L, ParamEQ_LM, ParamEQ_M, ParamEQ_HM, ParamEQ_H, ParamEQ_HC)
7 FloatingTiles with ContentType = FilterDisplay, each pointing to one ParamEQ effect
Knobs connected to Script FX1 parameters via property editor (processorId = Script FX1, parameterId = LCF/LF/LG etc.)

The problem:
When I call eq_LC.setAttribute(1, 500) from script, the value changes correctly (confirmed with getAttribute), but the FilterDisplay FloatingTile does NOT update visually at all.
What I tried:

Synth.getEffect("ParamEQ_LC").setAttribute(1, freq) → value changes but display doesn't refresh
Connecting FloatingTile directly to svf_eq_1 via ProcessorId → curve disappears completely
Engine.repaintFront() → no effect

My questions:

Is there a way to force FilterDisplay to repaint from script?
Can FilterDisplay work directly with scriptnode (svf_eq)?
Should I use ScriptPanel with setDraggableFilterData()? If yes, how to connect it to scriptnode parameters?
Would it be better to replace SVF EQ nodes with regular Parametric EQ effects and control everything directly from the property editor?

Thank you so much!

Thank you so much!

@the-red_1 You actually need to use the ScriptFX as filter display source

Add new external filter display by clicking the bottom right icon
Set all the filters in your graph to the same external filter in order to get an additive curve
Connect the floating tile to it and set the Index to the first external filter (#1 => 0)
