Hi folks, the attached image renders fine at 640x480. However, Terragen immediately shows thousands of errors at 6400x4800. Also, at the higher image size, Terragen switches to only use 30% of CPU instead of 100% of CPU. In both the small size and the large size, I'm using cropping to focus on just the upper right quarter of a larger image. Can anyone explain what this particular error means and why it is showing just at the larger size?
