Opening the PCD files in Open3D works perfectly, thanks!
In my tests however it seems that color information is preserved in Open3D when I export the point clouds in PCD binary format, but not when exporting in PCD "standard" format. This might be an error with exporting on my side though but I have removed 1.6 right now because I am rendering on 1.5.5
If you'd like me to check again please send me a PCD file with color info in non-binary format via DM and I will test it
Cheers,
Stephan
