Thread: FPrime Render antialiasing problems!

  1. #1

    FPrime Render antialiasing problems!

    Hi Guys,

    I'm rendering a scene that I have to render in pieces. I have AA set to Medium High. I am rendering using FPrime. The image is 1500 x 750. I let the renders cook to level 150. But I am getting jagged edges.

    What is going on, what am I missing?

    Thanks!

    AA settings in Lightwave don't have an effect on FPrime. Try letting it cook a while longer.

    Up your light quality to 0.8 or the likes. Could you post an example?

    regards

    Fprime uses light quality to handle balance between speed and noisiness, default is at light quality is at 0.5, i use lower settings for fast results, and for sublime rendering i up the value. Could be hot pixels in your case, you have jagged edges around a lightsource of a selfiluminating surface?

    WOW! I didnt know AA settings don't have an effect in FPrime. Thats great to know. I'll let it cook way longer then and report back.

    Clumsycloudy, its just your classic jagged edge crap that looks 'orrible. I hope cooking it longer will do the trick.

    if all fails, render on higher resolution (uses less passes) and downsize in ps..

    (light quality is set in the fprime master window)

    good luck!

    Ok, rendering now. Upped the light bounces to 2, and the light quality to 1.000.

    I don't know what I'm doing I just hope it works.....................

    worley says:"For example, if you render a scene to level 5 quality and you're happy with the edge and texture antialiasing but area lights are still noisy, a higher Lighting Quality will help reduce the noise in 5 (slower) passes without wasting energy with extra unneeded edges."

    so in theory if you dont have any noise but edges are jagged you should do the reverse; down the light quality so it will render passes faster and the edges get more attention... but thats a theory

    I'm just going to leave it for an hour.

    Generally, you can tell what settings will have an effect by changing them and noticing if the FPrime render starts over.

    Also, I've noticed some differences in the final output from using the render feature (where you just hit render and specify an output level) rather than the FPrime preview feature. (where you can watch it do its thing)

    Hope it helps... and how about oyu share some images eh?

    btw.. is this you? http://www.imdb.com/name/nm0362983/
