How to Remove Unused Textures from your Maps

[Obsidian]

This one's for folks who know enough about SLADE to put new texture sets in their wads, but not enough to remove everything then haven't used. Cut down file sizes and receive the blessings of community project heads everywhere with these easy steps!

 

Step 1.

Have a map.

Step 2.

Create a sector outside of your map.

Step 3.

Look for all the animated textures, flats and switches you used from your texture pack and put all of their associated textures and flats into the sector: for this example I've used ZGFALL1-4 (an animated texture), ZBGSTSW1/SW2, ZGGSTSW1/SW2 (two switches) and ZFGWATR1-4 (an animated flat) from Zoon-Tex. If you didn't use anything that animates from your texture pack, you can skip this and the previous step.

Step 4.

Save your map, then open it in SLADE. If your texture pack isn't in the wad, put it in.

Step 5.

Go to the Archive option in the top-left corner and then go down to Maintenance. From here you want the Remove Unused Textures option.

Once you've clicked it, a window should pop up with a list of all the defined textures: you can go through it manually, but SLADE should auto-detect any textures that you've used (as well as the IWAD textures) and mark the rest for deletion. Note that SLADE (or at least some versions of it) won't detect whether or not a texture is part of an animation of some sort, hence the necessity of steps 2 and 3.

Step 6.

Once you've removed the textures, go to the Remove Unused Patches option in the same menu. The prior step only removes the texture definitions from the TEXTURE1 lump, whereas this one removes the graphics themselves.

Step 7.

And finally, do the same for flats.
