func_rotating doesn´t work

[MilesTeg]

I just can´t get this thing working:

I made two brushes, one with "system/origin"-texture. Then selected both and made them "func_rotating", speed 20. But nothing happens:

The origin brush disappears (as it should be) and the other brush is doing nothing

 

Anyone here with a working func_rotating??

eh I made one, but when i activated it in the level it just up and vanished. I haven't messed with it since then
