I found a work-around. Basically I re-created all of my materials from scratch. I don't know what went wrong. I think it was partial user and partial buggy 2013.

I've come to realize the current mac version of SU13 is not up to par with '08.

Hello,

I am trying to update/edit my Materials by adding more wood textures.

Everything is working fine as far as adding the actual texture to Sketchup 2013. However, the texture names are not saving when I quit SU13. Even if I edit the actual .SKM file name, nothing sticks.

I don't know if it's a bug, or just user error on my part.

Thanks for your time!
Stew
