Ok I've had this problem for the longest time...
When Ever I use a texture (effects mostly Texture with writing ex. the Black Mesa Research Facility) I put it onto a brush(obviously) and the text is backwords, but when I look on the other side of the brush it appears that the text is correct, which is cool, but not when the opposing side (backwords texture side) is the side everyone will be seeing. This problem really sucks, I usually end up opening the ccopying and pasting the texture in Paintbrush, flipping it around, then putting it into wally to make a knew texture... Which now Im getting into my next problem, When I try to put the newly made texture into the Half-Life.wad file, It goes in fine, Until I go to save it, but it does
not save, so I end up making a new wad file which sucks when I only use 8 wad files at a time. This doesn't just happen with The Half-Life.wad file, it happens with all the wad files, which pisses me off most when I go to edit my custom wad file, I have one texture in my custom wad file, and have 19 others(saved as bitmaps) that I can't put in, because I can't resave the wad file... So if anyone ran into the same problem and/or knows how to fix this, than thanks, Its not as complicated as it sounds, but too complicated for me not to know what the hell Im going to do..
Thanks
