I am having problems projecting textures. I am using Zbrush 3.5. When I select a texture, it will not display on the 3D mesh or tool, the only way I can use textures is if I brush. It on. It works fine in ZB3.2. Is there something in preference or someplace that needs to be turned on or off for it to work correctly? 
The new multiple texture support has changed some things about the way texture application works.
To apply a texture now, go to the “Texture Map” section of the tool menu, click on the preview window, and apply the texture from there.
Outstanding! thanks Scott 
Thank you so much!!
