I'm on an English version of WinXP. The file path for both the image and TER file was:
E:\Geographic Maps & Models\Terran\WM Ter\Butte Canyon
I knocked the "&" character, and it doesn't crash anymore. Wow, picky picky, lol. That was the simplest solution to a mouse-throwing event I've ever seen. Thanks Oshyan!
I've been toying around with TG2 for a couple weeks now, so I thought I would share the first render I found satisfactory. The file isn't perfect, but it's very fun exploring the details. Enjoy.
