Low quality normalmaps.. What am i missing?

motives

hey, hoping someone here can help me out with this little normalmapping problem im having. Been tryin all day rendering out a normalmap from a wirefence mehs i build earlier today. However my normalmaps seem to be really low quality an like jagged in the edges.



I noticed this was mentioned in poops tutorial and that the solution was to make sure global supersampling was turned on. This however doesnt help me at all!

Here is my settings for the renderer:


Hopefully someone can point me in the right direction here since im kinda clueless whats going on.
If there any additional info on my settings you need just ask and i tell.

anti ailising! Turn it on, man
Also, use Catmul Rom for the 'filter' setting, instead of AREA.

I'd probably throw a background plane in there so that you don't have all that red from ray misses. That way it'd be at 0 for the normal, and blend better.

agh that seemed like an awesome idea vassago, too bad it didnt do anything for the quality of the normalmap

Im really at loss her.. can it be hardware related someway?

arshlevon

cant be a hardware problem.. rendering dosent use hardware.. just your processor.. try turning on a supersampler like hammerslay.. and also put a plane behind it like xenobond/Kman said..you might also want to turn padding off.. 0 pixels

Cheers arsh, turning off padding sorted out the jagging!

ya whenever you have need alpha you have to turn off padding because padding is done as a post effect, after the AA.

You could try baking the map out at twice the intended resolution, and re-size it down in photoshop.
