Rendered in 0.95 for some reason the rendered one with Anti-aliasing came out very different than w/out AA
here's with

and w/out

The wall is what I'm wondering about the most. It seems as if it's messed up. It's a texture w/ a bump map.
Thanks.

Wow. I was just playing Crisis Core on the PSP connected to my TV and it got me thinking about trying animations without AA to make it look more like a game. This really makes me give that a second thought!
It looks like turning off AA also turns off perspective correction. like when you see old PSone games and wall textures all go off in funky directions.

The problem is with the bumpmap. It seems that without AA the bumpmap is rendered differently than with AA. I can't say much about how it works, but I believe that the antialiasing actually smooths over the bumpmap a bit or something.

i had a similar issue back in 2006 when i rendered a shot of a city for a short movie, because i had textures on all the tower blocks, rather than bothering to model all those hundreds of windows :P. here's a still, with AA on:

(sorry, don't have a non-AA available!)
i didn't have any bump maps, but i still got a significant difference between AA and non-AA renders. i suspect it's an issue with all types of texture, but perhaps more so with bump maps due to the fact that they actually change the shape of the object surface?

Okay. Well I'm going to to be rendering my final scene in AA so really I don't think it will be a problem. I'm just wondering why it did it.
