I've had UDK for a few weeks now, and it hasn't failed me ever. My knowledge of the UDK is growing rapidly (thanks to your tutorials and Raven's vids on Youtube Honestly, I love it!
But today I was fooling around on it and I wanted to make a waterfall map. I went to add a terrain layer and when I typed in 'Grass', it said "Name contains an invalid character : "
I had no space after/before it either. I tried everything I could think of. I restarted UDK, restarted my computer, etc. No luck. It's just not my weekend, either. My Xbox 360 is in Texas right now due to the RROD
Anyways, what is going on? I'm probably doing something really dumb because of my n00bness.
