Niagara System issue with sample texture velocity

Hihi, I’m trying to create a chladni plate effect and i have followed this tutorial here:
https://youtu.be/CrOWIqJcguM

However, I encountered an issue and unable to solve. The particles don’t seem to be converging towards the pattern lines or the sample texture lines but instead it just keeps moving towards a direction diagonally. Changing the velocity scale to negative just have it moves diagonally in the other direction as well.

Under particle update I’m using a module set parameters> velocity> float3(Particles.SampleTexture.SampledColor.xyUser.scale, 0.0) / Custom HLSL! */

any idea why it doesn’t convergence towards the lines of the pattern like in the video tutorial does? I’m still very much a beginner so any help would be much appreciated!

Hi abeautifulglitch

This is exactly the same issue I am facing too + where the black areas are, I’m also getting small amount of particles.

Did you ever solve the issue, if so could you please share.
Much appreciated, thanks
