sorry but I dont understand your setup at all. You are using sampling PNG inside Niagara and spawn Particles based on values of pixel, or you are making RT inside Niagara and than you spawning particles that are drawing values into PNG?

you have to prepare material in different way. 1st of all you have to select different channels from that png, easiest way (couse theres like 10 different ways to do so) will be this one. You are selecting with channel you want to sample with DynamicMaterialParameter, so if it will have 1,0,0 value: you will get only red channel (remember that you have to put white in luminance factor in desaturation!). Than in Niagara you have to add SubUV Module, it should get values that you put in SubUV in RenderStack automaticlly, and DMP for selecting channels
