Pointclouds have wrong colors in engine version 5.1

Point clouds imported into UE 5.1 have the wrong colors. They are both inverted and shifted, for example, the yellow in this cloud I imported is inverted and blown out but the white is displayed as white where it should be. Everything also has this blue shift on it. The cloud is a .e57 file that was imported both into 5.1 and 4.27. There is no problems in engine version 4.27.
I’ve submitted it as a bug but does anyone have any suggestions for a fix as I wait? This is a crucial part of my pipeline for a current project at the moment. I’ve made a material and tried to play around with the vertex colors but have had no luck.

I would be able to say how, but, could you do a fragment shader to substract a bleu value to the fragment ?

I am also having the same issue. In my case it’s not a problem, but it could come annoying to have a bleu shifting.

Hi Mumchina,

I believe this is only for .E57 point clouds. (According to this bug report) So I wonder if converting the point cloud to a different format before importing will fix it.

For shifting the colors in the context of point clouds. I think doing it with post-processing would be the best thing to try first. For the rest of this month (Mar 2023) this post-processing pack is free on the Marketplace.
