Has anyone succeed to access the specified cell of a Grid 2D Collection in a Scratch Pad in the Particle Update stage in Niagara System?
What I want to achieve;
-Niagara System contains two elements; Grid 2D Collection and grid-shaped layout particles, whose resolutions are the same
-Contain 2D simulation result in a Grid 2D Collection
-Assign the simulation result as an attribute of corresponding particles
What I’ve tried;
-Create a Scratch Pad in the Particle Update stage
-In the Scratch Pad, add a Get Previous Float Value node that takes the Grid 2D Collection input as a reference
Issue;
-Execution of the stages in the particle emitter stops at the Scratch Pad
-Even if I specified the index of the cell to read (like {0, 0}), the result was the same
-No error messages on the Niagara Logs
Any help is appreciated.
