I am working on a project that requires custom materials for simulation, which I keep on a *.sldmat file. I recently moved my project to a different computer. I opened the assembly, pulled up the "Edit Materials" menu, and noticed that the "Open..." button for .sldmat files is disabled. Is there another way to open such a file? Why is that button disabled in the first place?
I change computers very frequently (working in a university computer lab), and when I have in the past, I haven't had any problems like this.
