Title: realtime render AA
Post by: bobby88 on July 18, 2011, 01:07:14 AM
When you click "use realtime render" does AA get applied to the image?
Thanks.

Ok, thanks, but how does that work, the more you let it render the more it adds antialiasing? Is it a value I can preset?

Also, what's the difference between setting it to render in frames or in seconds?

Forget frames - uncheck it. Only set seconds ... you can type in a higher value if you want. You can always stop the rendering early if it is good enough ...

If you work in an environment where people have different computer setups and you want a consistent quality then use frames. Only use time when you need it in a certain amount of time, would be my suggestion.

If you use time on a simple scene, then a very complex scene, then the quality won't even be close to matching. If you use frames, the complex one will take much longer, but the quality of materials, shadow, lighting, etc will match.

I have to use frames for iRay in Max because I render on a bunch of different computers and I want every frame to be the same quality even if it takes longer on some people's computers.


Also a good trick to find out how many frames. Do a few regions of noisy areas and watch the frame count. That will give you a good idea of how many frames you'll really need for the completed image without having to wait a long time. This should be done at Full resolution for proper results, which is why you only do a few regions. Smaller images will require more frames to look good than larger ones.
