I have run into a snag I didn't see coming. I am able to import custom textures files in my project and still use CC3s skin editor under the modify panel and any other texture editor in the program, but if I need to hand over the project to someone else on a different computer any custom textures that were imported are either lost or don't work.

My question is: Is there a way of saving a project file and include any custom content that might be part of the project, so it can be used on a different device?
There might be a project folder where all texture or model files might be located to be able to package it with any project files used so that it can extract the custom content, but to my knowledge there is either not one, or I haven't been able to locate it.

The biggest reason I can't go back to use none custom content is that I would need to practically redo all my work and spend at least a month or more doing so. Any suggestions or answers are highly appreciated as I haven't found anything on this subject. Thank you for any advice you might have.
