You really should post questions like this on my forum at
www.sydius.com. Simple reason is that I check those forums every time there is a post, and it?s a cold day in hell when I check these forums, since the majority is Dragon-related. I haven?t any experience with Dragon, so I don?t bother coming here much.
As for your problem ? that is odd. You ARE using a true-color image (24-bit) for tiles, and an 8-bit image for altitude, right? Both RAW? What version of TSMC?
Like I said above, might want to post the answer on my forums instead if you want a fast reply.
