Think you can add an option to export a "MeshLab"-esque .obj with the vertex colours? See : https://gamedev.stackexchange.com/questions/21303/how-can-i-include-vertex-color-information-in-obj-files but perhaps export it as a .objv or something? Mesh Edit would then be invaluable.
Hi Dyarosla, thanks for the input!
I've been looking into a way to export the vertex colours but all the methods involving .obj files are a bit too specific to work with MeshEdit. I'd really like to add a .fbx export so that colours can be included, but it'll take a long time before I start on that feature.
