antialiasing strokes

[lostpencil]

Umm... in your render, right? Do you have any anti-aliasing on in render globals?

[thesaint]

this is a common problem. Turn on motion blur, even if there is no movement.

For some reason this trips the switch to AA paint FX.

Because Paint FX is a post render process it is hard for Maya to AA during the actual render, but if you add motion blur (which is also a post render process) if then recalcs the AA through the Z buffer.

Don't ask me why or how -- all i know is it works!

Hey Thesaint, isn't that strange... I don't have any problems with anti-aliasing on paint effects and I have AA set to low quality with no motion blur.

Hamburger, do you have a scene file that has the paint effect in it that isn't getting anti-aliased?

hey thanx alot
i will try that tomorow when i get back to work

maybe i can up a scene file then too

thanx again

hey turning on motion blur made them good for a single image


butt for video they still march like crazy

it would be great if i could just drop a shader on these strokes some how so that they would antialias normally and i could render them w/mental ray

i don't think at anti alias at all right now cause paint effects is a post process



he is a slimmed down versiaon of my scene

so does any one know of a way to make strokes into geomatry easily or anything????
i hear that paint effects to geomatry is going to be in maya 5
woohoo


thanx

I'm not sure what it's supposed to look like, but here is my render of a frame. Looks fine to me, as far as aliasing. What do you think?

[lostpencil]

Oh... by the way, if you are viewing it in Explorer 6+, make sure you expand the image to the maximum (hover over the image and then click on the scale button that appears), otherwise the render doesn't look so good :)

Render the paintfx in their own pass at 1.5x or 2x the resolution and scale them down/composite them in post. Paintfx renders at almost the same speed at higher resolutions(maybe a few seconds longer). So you won't see much of a speed hit.

thanx guys

i was rendering at twice the size and scalling down
but if i understand what your saying i should render them at a like 60 frames per second or something and scale the time down too????

i will try that i guess

thanx for posting the render too

i guess that is kind of a bad frame to render i think the closer ones looked worse

and it is mostly when they are moving now (the marching) that is really bothering me

i think w/ scaling it down from twice the size it is much closer

thanx all
