Unable to pack files/can't find missing files I'm using Blender 2.78 to mesh clothing (obj file imports) created using CLO3D software.
For several months, I'm been making clothes, exporting them as objs, importing them into Blender, and meshing them for a game. However, this week, I'm having an unusual problem.
Some of the clothing that I've made and exported use mesh fabric properties.
The properties render properly in Blender.

I noticed 2 changes:

The mesh portion shows up in the 3D view port as a purple patch on the obj when before it showed up as whatever color I had the mesh fabric set to (usually black).



When I have my obj imported and I try to save my blend file I get the following error message:


Unable to pack file, file source (CLO fabric title.jpg) not found.

Which is strange because I have been able to properly mesh items containing mesh fabric from CLO's program in the past. I always use Blender 2.78 and I haven't changed my settings. CLO3D is installed on my computer including the folding containing the fabric .zfab files (which is typically what Blender uses to recognize the fabric properties).
I don't know what prompted this change. I have tried resetting my computer and reinstalling Blender and CLO3D, but the error still remains. I have no idea how to remedy this and when I try to find missing files in the external data menu, it keeps saying files not found.
It is happening because Clo no longer supports JPEG files for fabrics.
You now have to spend $5K for their fabric kit to render your own textiles.
