JUST SIMPLY CLICK "B" ON YOUR KEYBOARD!!!!!!!!!!!!! YOUR SOFT SELECTION IS ON!!!!!!!!!
XD
GOOD LUCK!!!!!!!!
You're wrong. Even in soft selection mode maya usually highlights your selections.
This was driving me crazy. I am not sure if this will fix your problems, but it fixed my issue. Renderer - Veiwport 2.0 options - Turn off Ambient Occlusion. For some reason it wont show selected faces while on. Hope this helps someone.
I had the exact same problem and when I hit B nothing was happening, but then I hit it multiple times and it worked, its nearly like it had to cycle through something, it wasn't working straight away but I hit B a couple more times and it was working then.
One additional thing. The Viewport "Show" menu option has a "Selection Highlighting" checkbox. Make sure this is checked.
If that still doesn't work, choose "All" in that same menu and try again. And this is a 'per file' option.
