jagged normal map border edges

adraps

guys, im getting jagged border edges in all of my normals. i tried all kind of AA filters, global SS settings. I know thay i can render double, then down size it, but i wish to know why this is happening. Only those borders are getting jagged, everyelse looks fine.

Can you show that its causing an issue on your model? It looks like padding to me, which is totally normal.

adraps

yes, its a 20 pixel padding. The fact is that only those borders (with and w/o padding) are getting jagged. is that normal? wasn`t suppose to exist at least an little AA in there?

If it's just padding, the edges shouldn't matter. The UVs would be no where close to them.

SkyWay

and if it's indeed padding, wouldn't it be logical to ignore it while supersampling to save time?

Noodle!

What SkyWay said, it would be completely pointless to spend computing power on that. The edges aren't visible anywhere except if you look at the normal map itself.

thanks for helping guys, however, i have a question. wasnt suppose to get Anti aliasing on those borders using supersampling/filters?? i really don`t know why i didn`t get them. :poly127:

I imagine you're not getting much jagged edges on the actual normal map borders (looks like a smooth circle from here). The padding is probably dilated after the map is all calculated/sampled/etc.
