Are you having trouble seeing MESH textures? There is a bug with the viewer! We have a quick fix for you!!
Take the item from your inventory list and rezz onto the ground.
*** MAKE SURE THAT YOU ARE EITHER IN EDIT OR BUILD MODE WHEN REZZING MESH AS THEY CAN BE TINY AND HARD TO FIND ONCE REZZED.
Rezz all the sizes out on the ground. Wear your size. The texture should rezz.
Delete the extra copies.
