You have seen, for example, which textures were used in Eviternity and you really like those textures. Now you think that some of those textures would look really cool in your pwad as well. So, how can that be achieved?
It is really quite simple when using a lump editor like Slade3.
To include textures from a resource pwad in one's own pwad is very easy when using any GZDOOM map format. There are several reasons for this:
GZDOOM does not need any TEXTURE1/2 or PNAMES lumps. Textures and Flats can be placed into the same TX_ namespace, so that any texture can be applied to floors, ceilings and flats. And, being BOOM compatible it can thusly make use of the SWITCHES and ANIMATED lumps. Another feature of GZDOOM is that several graphic formats are supported, therefore there is no need to convert the png format textures to standard DOOM format.
Now let's take a look at how this works with the textures from Eviternity, which uses the resource pwad OTEX.wad.
To copy the OTEX textures click on TEXTURE2 and then click on Edit Textures to open the texture editor. Or just doubleclick on TEXTURE2. The texture editor opens in a new tab.
With the texture editor open, highlight every texture. Then rightclick on one of them to open the menu Export To, then PNG file.
Then, in the Windows Explorer menu which consequently opens, select/create a folder where you want to store the textures, for example OTEX_TEXTURES. This saves 2536 textures as png files.
Close the OTEX Texture Editor tab and load your map.
At the end of the MAP namespace make new entries, TX_START and TX_END.
Save the map.
Now drag all textures from OTEX_TEXTURES to inbetween the TX_ markers.
Save the map
Now, all textures from DOOM2.wad and the new textures are available in your pwad.
Now highlight all flats in OTEX and copy/paste them to the end of the texture lumps, but still inbetween the TX_ markers. 1203 flats will be transfered.
Save the map
Since OTEX also provides new switch textures and animated flats, and GZDOOM is BOOM compatible, copy/paste the SWITCHES and ANIMATED lumps into your pwad. But do not place them into the MAP namespace or the TX_ namespace. I placed them inbetween those 2 namespaces.
Save the map
And done.
Note:
If the pwad is done in the pk3 format, then textures and flats need to be placed into their
respective namespaces instead. This is explained in great detail
here.
