This is a general Hammer question, so beware! I like to perform flip objects using the keyboard commands ctrl + L or ctrl + I, but neither are responsive. When I go to Tools > Flip Objects, Horizontally and Vertically both appear grayed out. I was using the command successfully last evening and earlier today during the same session. I've attempted it on different brushes, in different map files, restarted hammer, restarted SDK, and restarted Steam and I'm still unable to use those commands. I'm wondering if there is an overriding setting I may have accidentally changed that disables the use of that command? Has anyone else experienced this problem before?
