 I don't know if anyone remembers my little shrimp boat rendering I did for my job, but the exhibit is getting close to completion. Which is kind of cool to see the reality start to take shape, that was first represented with the CG. The perspective on the boat kind of weirds me out how it matches up with everything. The horizon line is right at my eye level (which is how I designed it).  The cab of the boat is a separate piece that's not installed yet.  Curator is happy... He's sitting on his rock-work.  That's me there. And that's a camera lens in my pocket, I'm not that happy about it. I also have pictures posted of the process up at my blog if anyone is interested.

Minor suggestion, think you should do something about the wood texture on the chairs, I think they're what give it away most. (coming from an amateur keep in mind, it's looking good otherwise)

'produce something of worth', he says! They're awesome. Anyone who uses max along with vray needs to get onto forest lite, stat - http://www.itoosoft.com/english/menu.php?id=forest_faq It's basically vray scatter, but it has a free version too. I did this in 45 minutes and it rendered in 10 - (excuse the awful colour balancing on the shrubbery, I didnt change the materials)  12 billion polys total, 2 of those billion just coming from the individual blades of grass. That is ALL geometry, stretching to just over 1km away. (although the grass breaks off much earlier) Also the entire ground plane is displaced mud. haha. The viewport loving flies with very little slowdown. It's completley bonkers. cubicle gangster fucked around with this message at 18:27 on May 14, 2009 |

Yeah I'd say that it's a resampling issue. IE the renderer goes "ok, this texture is applied to this plane" and then treats it AS a filtered texture on 4 big polys, there's bound to be some approximation when it interpolates UVs, resamples the image and renders. To combat this you can use a higher res mesh, and up the pixel sampling rate. Or render the UVs and add the cam map in post. With the camera projections above I'm doing all sorts of crazy warping on the UVs and geometry, so it's blurred to hell.

Ahh, makes sense, I'll have to give that a try one of these days, my usual work around for that was blending in comp, and motion blur, hah.

One interesting thing I did with motion blur the other day was accidently loving up my shader so that it just mapped the current frame of the plate on the fragmenting geo. Since motion blur was on, it looked like the plate was being distorted in all sorts of freaky directions. I must give this a go again to distort things like people's faces.

re: the houdino map thing - cant you just turn filtering off completley and crank up the AA to let that handle it? I'm stabbing in the dark here, but you can do that with vray. The results look awesome, if a little bright

There isn't really a standard AA setting per se, at least not in the default sampling settings. Micropoly renderers handle things pretty different to raytracing based ones, it splits each poly into tiny little chunks each with a corresponding UV value and then renders that. So really you want it to dice the geometry into smaller and smaller bits to give more accurate results (the pixel sample settings). Gah the sim I ran all last night has massive artifacts, I might not be able to do this with self collisions, drat.

Okay, question for people who do a lot of their own scipts and programming out there. How do you get to a decent level of ability at it? I'm self taught so I can accomplish very basic stuff, but more complicated scripts just have me stumped. Is it as easy as picking up Programming for Dummies or do I have to go through a Computer Science Bachelor's degree?

Yeah - the trees are modeled leaves, and the grass I modeled myself (at 5 polys each blade) Never used a 2d plane in a scene, always thought it looked like poo poo and now we can get away with 3d objects. It's a technique straight out of the late 90's. Sky is kind of a camera projection - I took a screen shot of the viewport from a camera with a wider angle, put the sky over it as I would in post then projected it onto a self illuminated plane behind everything. Gives me about 5 degrees either side of the view because I was going to do some basic animation. cubicle gangster fucked around with this message at 13:40 on May 17, 2009 |

Honestly a lot of it is just basic logic theory - syntax is syntax, but logic is universal. I would say UML flowcharting might help, but it's always seemed a bit...remedial? I wish I could recommend a book, but I haven't really read any other than some old java and c# stuff from college, though a generalized dummies book would probably do the trick. If you have any questions, I maintain a decent amount of maxScript (almost identical to java, syntactically) code at work, so I can probably help you out if you're stuck on breaking something down.

Ecodazoo is the best thing I've seen come out of Papervision and one of my favorite Flash sites in general. That said, I'd only use Papervision for web3d if you ABSOLUTELY have to use Flash. If that isn't a limitation for you, there are better technologies out there.

 Working on a new exhibit vis. Crits welcome. It's an interactive sea turtle exhibit. You can feed the sea turtles from the top area. I'll probably add some people using feeding poles and some more fish in the tank tomorrow. We'll be really pushing this exhibit this summer for fund-raising. It's the next big exhibit, although we are working on some smaller ones currently. This would be an actual new building added to our facility which costs quite a bit more than throwing in some new themed tanks and areas.

The only thing that stands out to me are the orange walls - they look a little flat. Maybe a subtle glossy falloff reflection, slight noise in the glossiness - just so it looks a little shiny and painted. Aside from that it's really good, the people are well matched.

if you're using the mia_material_x, you'd increase the glossiness of your orange wall shader slightly, and put a bump map on it to break up the highlights so they scatter a bit like they would on a painted wall. you can sometimes fake the effect without a bump map by just lowering your glossy samples, but it doesn't look as nice up close. that, and mess with the BDRF curve to tweak how reflective the surface is at different angles. that'll give you nice falloff.
