What resolution did you render at? If you're watching it at larger then the rendered resolution it will get worse. Could it be motion blur?

Hi Dolly, ... it's nearly impossible to get "clean" animation with VUE :(. There is always flickering ! Even with the highest anti-aliasing quality, the results are always average. I could once create a totally clean and smooth animation. But there was only a few primitives with basic materials (no vegetation, no models, no terrains, etc...) and it took ages to render ! The only thing you can do to reduce this grainy effect : 1. Don't use soft shadows. Instead use normal lights with high fall off and gentle shadows (40%). 2. Don't use volumetric materials and lights. 3. Always use motion blur. 4. Use a very high anti-aliasing (broadcast is not enough). 6. Avoid strong exposure changes (i.e. from light to dark). 7. Avoid materials with too many different colors and elaborate bump maps. Materials with variable highlights or variable reflections should also be avoided. Try to keep it simple ! 8. Always render at full frame uncompressed. Don't use any codecs (MPEG1, Cinepack, Indeo, DivX, etc...). 9. Choose 24 frame/sec or more. 10. If you can, render at 640x480 pixels and reduce the size of the animation in a video editor (premiere, final cut, vegas video, video factory, video studio, etc...). If you don't have one, there are some free video editor available at www.download.com. This will "soften" the animation. Before launching the rendering of your "Atlantis" animation, test all the materials in a very simple animation. You will notice that some materials are more grainy than other. The atmosphere and the lights used are also important. To get acceptable animations I had to create a specific folder with "animation compatible" materials and atmospheres... Hope that this will help ! By the way, how did it go with your 360 Atlantis panorama ? Are they good, can we see them ? Eric

I forgot n5 : 5. take it easy with the camera ! If your fly-over goes too fast, the motion blur will be very dirty. Eric

Hey all Thanks for the help but i sorted it lol all i forgot to do is compress the anim while rendering now i have an anim that looks as good as a still image lol cheers dolly
