Don't Antialias Against Background Option

(1/2) > >>

wild_qwerty:
I currently make a lot of sprites for a game where I need a 'hard' edge with no anti aliasing. Rendering the image with the Alpha channel and pasting it over doesn't really do the job as the image is still anti aliased against the back ground and while it might have a hard outside edge some of the background colours creep into the image so I get these colours in my sprite (looks like crap).


Anyway, this is how my friend does the job using 3d Max, could this option be added to Anim8or?

You can disable AA on outer edges in Max while rendering (I discovered it some time ago), so you can skip this whole "removing AA in PS" thingie.

Customize --> Preferences --> Rendering Tab --> Check "Don't Antialias Against Background"

hihosilver:
When go you "Render>Render Image..." Un-check the "antialiased" box ;)

wild_qwerty:
Not quite, I want to render it with AA on because it looks much better, but I don't want the outside edge of the sprite anti aliased against the background. When I add the sprite into the game the background will be transparent for that the sprite/model overlays the game and has a clean edge. Unfortunately with AA on you end up artefacts on the outside edge. With AA off the model doesn't look as good.

thecolclough:
so you're saying you want an option for selective antialiasing, with different parts of the same image AA or not AA, depending on whether the edge is against another model, or against the background?

almost cool:
thats what i got out of it.but opengl is whats rendering,so steve wouldnt have any control over that.
