How do I install Extensions/Plugins?
Fortunately discreet has made it very easy to install plugins in 3DS. All you need to do is unzip the plugin into the 3DSMAX/plugin folder and you are done…The plugin will show up in the part of the interface it belongs – material plugins will show up i nthe material editor, geometry plugins will show up as geometry, etc. Remember, 3DS is actually a platform where all of it’s functionality comes from plugins – whether they are shipped with 3DS or you download them, plugins are all accessed the same.
