No Geometry content at warehouse (Solved)

Hi, I was following a tutorial and trying to make a transparent skirt but when I've arrive to the part that I had to put "simglass" at Geometry on warehouse, Ive realized that doesn't appear any Geometry or anything else than texture.

I'm using "create 3D mesh" option and not a recolor.


Anybody knows why is that happened? And how can I fix it?

Thanks a lot.
