CourtneyCasper : Man this one is beautiful ! The fur looks so realistic, What is it made/rendered with ?

delpadre - Good start! We should talk about what you're doing with the lighting. Right now the shading on the fur looks very flat, and I can't see much variation of brightness or shadow. It would be good if some areas like inside the ears weren't as furry as other parts.

Perhaps there's something strange about the way the scene is rendered and composited, too, because there's a black edge around a lot of the rabbit, and the front of the rabbit's head and nose look transparent, as if the edge of the ground and sky were visible through the rabbit's head?


Courtney - I've seen your stuff before, but for the record it looks great - very good integration of the paint fx and fur colors with the backdrop.

Your rabbit has a thinner black edge than delpadre's, but it's still there. When the Maya renderer composites the fur image into the main rendering, it uses z-depth info that isn't anti-aliased, and makes those edges. Getting background grass, rabbit, and foreground grass rendered as separate layers with their own alphas, and compositing them in Shake or Photoshop would probably look better than letting Maya render it in one pass.

Thanks for the comments Jeremy. I am having some weird problems. If I move the lighting around or change the light properties it will render the grass in front of the rabbit as if the paint effects cover the entire rabbit. I also can’t seem to get rid of that black border around the rabbit, I assumed it was something to do with the lights shadow setting but I can’t seem to pin it down.

Also,when I try and use the paint effects artisan brush to reduce the amount of fur around the ears and other parts of the rabbit it affects the whole object, not just the part I am painting. Very strange.

Maybe I will try and render and composite it in Photoshop later as you suggested. I will mess with it again tonight; any suggestion on lighting would be appreciated!

quick question... when does this competition end? I didn't see it posted on the main page, and would like to participate if at all possible

Test render without shadows to make sure the black is really caused by the shadows, it could be an internal comping problem. Shadows of maya fur only work with tightly aimed spot lights (not other kinds of lights), with dmap shadows, but without dmap autofocus turned on, with fur shading/shadowing attributes added to the light and set for shadow maps. Then if you tweak the bias just right you can get pretty good shadows. (Hey, this is supposed to be a "challenge" )

You should be able to paint the baldness without affecting all of the fur, if you're using the NURBS model. On the polygon model you'd probably need to do some UV assignment before painting would work. If you paint the length, the moment it adds a fur attribute map for the length, you need to set the map multiplier under length details or all the fur will jump shorter into the 0-1 range of the map.

There is no deadline, and you can do any challenge at any time and post your work. However, if you do the challenge this month while it is the latest challenge, you are likely to get more feedback and have a chance to get your work in the challenge gallery.
