Using multiple obj files from context capture in Aecosim v8i ss6

Hello All, I have been using context capture recently and have been following the youtube tutorials for editing meshes in Descartes and then exporting as an obj. The idea is that I can composite several referenced obj files and some dgn architectural models and export to Unity for VR. The issue I am currently having, is that the obj file textures are getting mixed and muddled up when I bring them into the Aecosim. It seems like the textures are texture paths are getting confused when more than one obj reference is being used. I would be very grateful if someone could help with this . or maybe a workflow that might be more suitable.
Thanks,
Conor
