Son, why are you stealing my textures?
I died on the inside.
Just kidding. Found the problem. You did not define the textures in SLumped/Slade. I fixed that for you, but you must learn how to do it. Check out Mike's texture tutorial. It's really simple once you get the hang of it.
Get the wad again here.Now for some things:
- The way you're using the textures makes no sense at all! But seeing as you're starting this, I think you'll fix it.
- ALWAYS use 255 brightness on all rooms. Textures won't display right otherwise (fixed this as well.)
- Try to not use diagonal lines on the map layout. That usually makes textures look bad. Diagonal lines aren't bad, though. You just need to be careful how you use them. I recommend you use vertical and/or horizontal lines since you're starting, though.
Good luck. Mapping is never easy at first. Just be persistent, and go see the tutorials. They'll help in the long run.
What's funny is that I learned something new while doing this: replacing textures quickly with F3.
