Hello,
I need to save file as DDS format, so i tried to install the NormalMap plugin, but it doesn’t work…
What am i doing wrong?
I use photoshop cs 5.1 64 bits, windows 7

any help is welcome, i need it quickly!!!

Hi bibo,

You should be installing the 64bit version of the plugin if you are using photoshop 64bit and 32bit version of the plugin if you are using photoshop 32bit.

There should be an option to load and save dds file once you are done.
