Apparently maybe because I'm a new forum member I don't have access to post this problem to the "Interface, general usability and other problems" section so I'm posting my issue here.
I have a large library I created that has many 8K textures and creates a output size of 5.96 GB -the out put file only was created to export my smart materials only. I've exported smaller smart material extensions (2GB) and restored them fine but with the 5.96 GB extension size it wont install, the message just flashes the on my screen "it is recommended to exit 3D coat restart it to apply all changes".
Would anyone know what the problem might be? Each of the materials work just fine at this time locating the textures as it needs them located out side of 3D coat when I created the materials.
