since 5.8.0 Ribbon Emitters appear broken when set to GPU compute instead of CPU. Ribbons exhibit wrong link order and/or UVs and produce heavy visual artifacts.
Please note that these issues do not appear in 5.7 and below.
Steps to reproduce:
Create a default “Ribbon Link Order” Niagara system.
Change emitter from CPU to GPU Compute.
Expected: No changes
Actual Result:
UVs appear broken, can’t work with ribbon link order reliably anymore.
Platform:
Desktop, Windows 11, rtx 5090,
only since UE 5.8.0 and still in UE 5.8.1.
