I am producing a short animated film in Bryce 3. I have PIII 733, a bucket load of ram and high speed HD. Problem: Most clips are 10 to 20 seconds in length. While some come out almost photorealistic others have this damm twinkling. I did a render of a craft approaching a city. Itlooks good until the city is reveiled and the whole thing twinkles and looks terrible. I realise the moving clouds could be the culprit. But how do I maintain the atmosphere without the damm clouds moving. If you have the answers for me, I would be very greatful. Marty
