Issues with joining 3D scanned OBJs We work with another program to first create a human head with particular facial features, then we try to join it with another scanned mesh (the human body) in Blender. Both are in obj format.

The problem is when we use Ctrl+J, it mixes all the colors and one of the meshes loses its colors by doing this. Is there another way to join the head and the body without losing the real color of both meshes?

This is the result of the joining in Blender software and the other is obj obtained from the 3d scanner directly, and I need to preserve the colors of the face and the body individually
Here is a procedure for baking the color from a 3D scan to a UV map in Blender: https://software.intel.com/en-us/blogs/2015/03/24/RealSense-3D-scan-Vertex-Color-to-UV-Map-Blender

Follow this process for both meshes (the head then the body). Then try to join them. If the textures are baked and applied via a UV map, both colors should remain when you join the meshes.
