Ok, so I got a workaround by manually launching Hammer, however when loading my map I get a message along the lines of “Failed to load the default scheme file, the map views may be missing some visual elements”. As far as I can see, this has removed the distance shown by brushes, e.g how long, wide, tall they are. This makes it extremely tricky to do things right.
As well as this, Hammer crashes (with no error message) when I attempt to “browse” for models to select for an entity.
And finally, all the models I had previously done on another computer (without all these problems) have now got pink checkerboard skins in the 2d views, but they’re fine in the 3d view.
Can anyone help me?
