Great add-on! I tested with some Houdini PLY -> MeshLab -> Blender. No idea why Houdini PLY color does not work right away.
I am wondering if once the data is loaded and displayed, perhaps we can change the point size like in Meshlab?
Just wondering if I could turn this add-on into a node? For Sverchok or Animation Nodes? So that maybe the point data can be used further to generate instances?
