Every time I make a brush and hold "Ctrl+T" and change the brush "func_detail" to "func_breakable" press enter, click the apply button 5 times! and set the settings (http://imgur.com/oRkpWE9) and double click an other brush to open properties of that brush and double click the brush that I changed to breakable, and the VISgroup window appears, so hold "Ctrl+T" again set it to "func_breakable" set the settings did what I did last time, but it changes still. Wondering why it changed, and I wanted it to stay as "func_breakable" but no matter what I do, it keeps changing! :cursing:
