SUBJECT: My first render of the wet cave (challenge) KEYWORDS:
On the main screen, there's a series of small triangles along the left side of the preview. The very bottom one, which is just to the right and below the trackball- click it and that's the place to change all the fun settings like gamma correction, anti-alias settings, etc.
And I HATE that interface when you're trying to tell someone where something's located! ARGH! "Click the spinny dealie next to the whitish swirl thing while you hold the secret key combination". = )
