Just recently I found a post where KILLSU2 explained how to make your custom textures
visible in D3Edit's texture palette.  So what does this have to do with Objects?
The same method has objects (clutter, powerups, robots, etc.,) visible in D3Edit.

Not only do they show up in the object palette, making finding them easier, but they will also be visible
in the 3D window and Level window when textures is on.  This makes it easier to position and orientate
your custom objects.

When you are done making the .oofs you'll be using and the you have set up a custom .gam file you  need to make a .hog file.  Do by making a .mn3 file.  An .mn3 file IS a hog file.   Just start the MN3 Packager and add all the custom .oofs, ogfs, .oafs and the custom .gam file using the Add File(s) button.  You do NOT need to add a level or set up any mission information.   Save it as anything you like.  I'm using my .mn3 from vortext2 as an example but you could name it Custom.mn3, Temp.mn3..... whatever.  Remember that this isn't your FINAL .mn3, it's just a temporary .mn3.

Start up D3Edit.  Before starting or opening anything you have tell D3Edit to load your .mn3 (hog)  along with the d3.hog for making objects and textures available. Go to Data-Configure A Mission Hog as shown to the right.

This will bring up the Mission Hog Configuration box.  The textbox should be blank to began with. Click CHANGE and browse to your .mn3 file.  Select the .mn3, click OPEN and you'll see the path entered into the textbox.  Pick OK. Your hog file (the .mn3) is now loaded and available for D3Edit.  Now you need to select the .gam file from you custom .mn3.

To do so, go to Data-Tablefile Manager.  On the Mission Tablefile line click HOG Browse, not File browse.
The HOG File Browser comes up listing .gam files available from loaded hog files.  Select yours from the list
and close the Tablefile Manager by picking OK.

That's it!  You're custom objects and textures are now not only available but VISIBLE in both your
selection palettes and your textured views.

Below you see the benefit of taking an extra five minutes creating your .mn3.  You can see you object which will help you position it and know which way it's facing.		You can use a custom .gam file without  setting up an .mn3 but you won't see your custom objects or textures.
