I'm guessing that the decimal following the error text is the actual size of the texture?
Yep, that's the scale that violated your tresholds. The line number is given in front of it, and .map files can be opened with simple text editors like Notepad. I wouldn't recommend MS Word for these plain text files. Personally, I use
Notepad++ for things like this.
Yes, you can edit the .map file and load it into Hammer, provided you didn't make it an invalid .map file of course.
Tommy14 recommends scales between 0.1 and 10 bytheway, so I think those would be good tresholds.
A suggestion for future versions would be to add the brush number to your list as well as the texture size and a method for saving to a log file.
Good suggestions, I'll see what I can do. The logging is definitely a good one, I had it in mind when I was busy with it but thought, oh well.
I figured out how to get brush numbers now so that's no problem either.
Too bad this wasn't the cause of your problem though...
