You seem to be in trouble again. All the problems you point out are on map_c.
It's nothing to do with textures.

Just open "Mymap_c" with Gimp, select the Brush tool & choose a small brush (Circle Fuzzy 03).
Make sure "Opacity" is off. Then paint out the bits you don't want with black.

Remember to put it through the map_c converter again.


Cheers
