[Niagara] Sample texture more precisely or alternative for point cloud data

Hello,

I’m trying to render a point cloud using Niagara. I’ve gotten very close except that there seems to be some straight line gaps between the particles. I’m using an EXR 32 bit texture with each point’s XYZ coordinate encoded as RGB (one particle per pixel). Using a UV index to address the map seems a bit imprecise. Is there a way of getting the RGB data using pixel coordinates instead? Or is there an alternative to texture maps that could work to get point cloud data into Niagara?

Thanks!

Guess you should uncheck sRGB,use NoMipmaps and set Filter to Nearest

Thank you profhua! I was already doing no sRGB and NoMipmaps but it was setting the filter to Nearest what I was missing and what fixed it.

Cheers!

Hello,

How did you manage to bring pointcloud data to niagara. Would be amazing if you can share some knowledge.

Thanks!
