Find the material you want and open it in the material editor.
Highlight all the material functions and press CTRL+C to copy them.
Leave the material window open.(you'll soon need to copy the settings/properties)
Next create a new material in your map package and open the material.
Press CTRL+P to paste the material functions from the original. Re-attach the functions to the main material function panel as they are in the original material.
Next tick in the "grey space" so NO material functions are highlighted.
Set everything as the original is(mainly lighting stuff) except the doublesided option which you can now enable.

As this map will run within UT3 you can use the above method as your material will still have working access to any textures that the material functions require.  eg.. Look at the "Texture Sample" functions in the material.  You'll see paths in the Texture Sample properties that point to the stock packages!

However...if you were being a bad boy and were going to use UT3 assets then eventually import your map into UDK then you'd need to follow Steves method as the base textures for the material would need to be duplicated into your map file so the material functions can call to the textures within your map package rather than the UT3 stock packages which don't exist in UDK.

Hey cousin,

3 steps only,

- Duplicate the material in your map package (as you already done).
- Open the material editor of your new material, just activate the function "TwoSided" as show.
- Save the changes.



That's it ;)

 

PS: it's a example of my glass mat in Citius.

LOL

Well cousin, which part is unclear so I can try to make it more simpler ?

Well, all those character []()" are only to help you understand the syntax to type between them. They act as quote.

If you see the underscore character, the _ well that mean you must type it because an empty space won't have nothing, it's a blanck space.

The best advice I can tell you is copy/paste this line :

obj savepackage file=C:\Temp\ToDelete.pkg package=

& type the package you want to duplicate at the end like UN_Cave (yes the _ is required if my memory is correct).

For example, the full command line would be :

obj savepackage file=C:\Temp\ToDelete.pkg package=UN_Cave or
obj savepackage file=C:\Temp\ToDelete.pkg package=NEC_Walls or
obj savepackage file=C:\Temp\ToDelete.pkg package=LT_Walls

Remember to delete C:\Temp\ToDelete.pkg when you close the editor so your HDD don't keep those temp files.

Can I has a thread for DM-Insidious? I tested it, and would like to give some critics to the beta.
