good tip, Bruno, I gathered something sim. from more in-depth study of R.S.s website.

I did many test renders tonight. 

I have a machine with (2)dual core processors and 3Gigs of RAM.... keep that in mind as you read that these render times are on a machine using 100% of all four processors.

I will try to get RSpaulding to post them on his site.

I rendered the same frame w/ GA at +1.5.  I have my sky gain to 1.0, my lighting set at like .54, 75, 100 for those 3 sliders. 

I turned off indirect light and shadows on veg.  I rendered over and over with TAA OFF and OAA at 65, 70, 75, 80, 85 respectively per render. 

All renders were at 720x405 (regular television quality, widescreen 16:9 aperature)

I don't have the times here with me but they were something like 7mins for the 65%OAA quality to 14min40secs for 85%quality

I then did something interesting, I checked the little box in the OAA that basically meant TO NOT optimize the OAA... I'm at home now, sorry I don't remember what the little box was called. and ran the same render at 85%... the render time INCREASED again by almost 1.5mins to around 16minutes.  HOWEVER - the quality of the AA was more accurate in my opinion.  Some of the highlighted areas from the previous 85% render were now less washed out, and more details could be seen, while overall the vegetation was smoothed nicely from what I could tell.

To get rid of the pixelation of these images, you are correct Bruno- higher object anti-alias (OAA) is definitely it... and I can see that 95% or better would be perfect, while 85% is probably close enough for government work.

However, as an architect, I have deadlines, and they don't allow me the luxury (although I'm using all 5 render cows to their fullest extent) of tying up computers for days and days to render.

So I chose 65% quality and chose NOT to 'optimize' the OAA, so there will be a bit longer render time than 7 mins/frame, but hopefully it will finish before the weekend is over... and hopefully it will not have the pixelation and light and dark ripple-like effect on the brick surfaces of my last animation.

I should have tried baking the indirect illumination to some of the model, but when I tried that before it increased my file size by something like 500%!

Any tips on baking illumination would be welcome... to bake or not to bake, that is the question.

I also didn't weld my model... maybe I should have to see if it effects render times... I don't know.  Tips on that would also be welcome.
