You should have a look at the pyro tools talk- specifically the shader talk by Mario here: http://www.sidefx.com/index.php?option=com_content&task=view&id=1496&Itemid=305 He talks a bit about his observations of gaseous things, and how they absorb, emit or scatter light. You can get this going in the pyro shader if you name your field/s appropriately (Use a name SOP). And then you can tinker with the pointcloud lighting features the shader has for your internal scattering.

A good setup to use actually would be get the shape you want from a lower rez volume, and then use an uprez setup in dops to unrez the volume, that and you can use a displacement shader with the volume shader and that'll give it more detail. Oh and Heintje, I forgot to sign up for the class thing on Monday, but let me know if you guys want to make a bar night, I know a ton of bars all around that area that are great to hang out, have a drink and do some chatting.

Oh, I hadn't even thought you could use displacements with volume shaders, but really, why not. Should be worth examining. Though still, I hope I'm not getting annoying here because obviously you guys don't seem to think this is a very fruitful approach...  Here's a quick test, I comped my own smoke next to the one in my reference photo. Does it look different in actual context? It's not a perfect match of course, but at least to my eye it doesn't look too bad. Which sort of suggests that this could be made to work, at least with reasonable viewing distances. And for comparison, the original:

I think one of the major differences is the lack of evidence of motion, ie how the dust puffs 'pull' the gases up and leave streaked columns underneath the heads. I like watching this video. It's hypnotic. http://www.youtube.com/watch?v=yFAf_SRRKUg

DefMech posted:Archviz is a weird field. It's one of those things where you can make a really good living working out of your house alone or if you work at a top tier shop like Mr. Gangster. It's hard to survive in the middle. Right now is a bad time to get into the field, IMO. Before my company shut down back in May, we were having a hell of a time convincing architects and developers that an extra few thousand for renderings or animations was worth the expense. It seems odd that just a few grand on top of the total cost of a project would be such a dealbreaker, but that's the industry right now, I guess. Considering I got laid off from my job of doing (among other things) Archviz, and I've been out for months still with no job, yeah, don't go into that field right now.

Trying to get the penis to non-penis image ratio down lower on this page. I redid the topology on the face a bit. I'm updating an old model and the topo was hideous on the old one. I took some shortcuts. It's still not perfect, but it's better. Crits welcome, this is still a work in progress but I figured I'd see if anyone can see anything weird about it now. I got rid of the white eyeballs, and just went back to the more neutral look, and I shrunk them down quite a bit. I've still got some more to do on it.

Of course this is based upon the assumption that this is the look you're going for. I'm not going for the look of the Tin toys. As for the bead, it is a bit of ornamentation along the seams of where the various pieces would meet together, to help ease the transition. My idea is that everything would be put together with rivets. I'm not really done with the riveting as of yet, because it's hard to keep it attached to the geometry as I tweak stuff. This is what I had in mind for construction type. Just a GIS image, not sure who the bloke is:  Trying out the bolt eyes, any better?

I think the fact that it's got round eyeballs that fill out its sockets perfectly is what's making it look human to me. I do like the nut irises though. I got a new project, as I'm sure you're all thrilled to hear, and I'm working on the composition and lighting. Here are some screens:   That thing on the door is painted on (poorly) just to show where that light will be coming from.  And here is a video: http://www.vimeo.com/5672811 How am I doing so far?

It doesn't look like rivet/weld construction, it looks like you're gluing tubes and dots to your model. Get some better photo ref that is closer up to a weld. Here is an article on welding with some good photos: http://www.mig-welding.co.uk/gasless-mig.htm And then here is wikipedia on rivets: http://en.wikipedia.org/wiki/Rivet and here is a link to some rivets: http://www.rta.nsw.gov.au/environment/images/heritage/4301052b9.jpg Right now your rivets are not round enough, it looks like you flattened a sphere. You might want to look into a different kind of rivet, too. The welding is just floating on top and not at all mated to the metal - you might consider taking this into zbrush and sculpting the welds, I don't think you're going to quickly model some good welds without a sculpting app.

Who is up for a little competition. Well competition isn't really the right word as its more an incentive to do work over finding a winner; but we could do like a low, medium and holy poly challenge, maybe an environment or building, character, vehicle etc. Low would be super low like 500 tris maximum and a combined texture space of 128 or 256. Medium would be game spec I guess normal maps allowed; high would be whatever your pc can handle! Anyone interested? I was thinking first off we could make a 'military vehicle', be it a space plane, a steampunk laser gyrocopter or a WW2 sherman tank. What do you think? edit: and we could make the render/beauty shot look like the cover of an Airfix box! brian encino man fucked around with this message at 18:38 on Jul 20, 2009 |

I would like to try a little hard surface modeling in zbrush, and it will be an excuse to make a new piece. Count me in. EDIT: I saw enough CG dong in Watchmen to last a lifetime. Seriously though, EoinCannon, that is looking really good. I plan on transcribing those CG con notes today, so you guys should see them up soon. Hinchu: You may want to consider subtle impact point / dimple around the rivets. Either that or paint in some occlusion or grime around them, depending on age etc. sigma 6 fucked around with this message at 22:01 on Jul 20, 2009 |

Andrew Jones http://www.androidjones.com/ Art as a journey Warns there are too many aspiring concept artists but not enough job positions to go around In order to succeed as an artist you must first find a need / niche Helped found conceptart.org Warned of falling into one of the 4 major archetypes (child, victim, saboteur, prostitute) Advocates painting outdoors (celestial events / sunset / sunrise) No reward without some risk "Phaedroid" performance Daniel Williams (Zbrush) http://www.pointpusher.com/ (toolbar for maya available for download) modeling head: subtool master will allow mirroring of subtools use flatten with low intensity to flatten parts like foreheads / temples Uses falloff brushes from zbrushcentral vs the pinch brush Always work low to high use move at low levels to change primary form and pose check profile / shape of nose always be checking in multiple angles as well as ortho check 3/4 view as well as front and top for general shape of head To retopo in maya: import sculpt -> make live -> create poly (make strips) -> triangulate -> quadrangulate -> add edge loops and tweak verts where necessary new verts will snap to live mesh check normals on strips of polys occasionally build an animation ready mesh strip by strip / patch modeling Merge strips / patches For making posed head / posed blendshapes use maya's non linear deformers and clusters after using deformers re export back to zbrush for further sculpting note: zGo or zbrush 4 should make import and export of blendshapes / morph targets easier Paint / smooth cluster weights for fine control It's okay to model with deformers in maya (pt count should not change for import/export however) Ask questions about your character through every step of the process Section character into subtools or polygroups or both Each subtool isolated can use up to 100% of cpus resources Sectioning character into polygroups can be better than subtools because one can sculpt across polygroups a lot easier Xnormal is better than Zmapper because it is topology independent How do you know when to move forward from base mesh in max/maya and just sculpt in zbrush vs starting with bad topo, sculpting, and then just making a new game mesh over the sculpt (retopo)?? - If you already know the specs of the character beforehand then start with a base mesh in max or maya - If you don't know really know where you are going and plan on exploring more at the beginning stages in 3d, then start sculpting the form in zbrush and just retopo later. Jeff Miller (Zbrush) http://redrepublik.cgsociety.org/gallery/665298 Start with z-spheres, retopo later if you need to z-spheres (preview mesh "A" -> make polymesh3d when you want to convert from z-sphere to poly) Reuses basemesh created from zspheres for many different characters, posing them differently using the transpose tool For facial modeling he uses clay tube brush + some gravity on the brush for wrinkles Uses claty tubes for putting in muscle -> smooth them out (clay smooth) Use clay for filling in volume When masking it is sometimes better to do it at lowest subD level to make it as precise as possible Use falloff brush from zbrushcentral vs pinch brush (pinches topology = bad) To create stylized hair use falloff + masking + flatten brush Always step down to lowest subD level before saving! This insures better stability in file. The more tools you have in your zbrush tool palette the slower zbrush runs You can separate / group you character according to UV shells (polygroup -> UVgroup split) Don't just add detail around your entire character uniformly, add detail intelligently and in the right places Typically spends a week on a character sigma 6 fucked around with this message at 09:24 on Jul 21, 2009 |

Ok how about this for the first challenge: You have 4 weeks to make something on the theme of 'military machine'. This can be futuristic, alien, eco-warrior; it just needs to be ready for some kind of combat. Let's go for the middle ground right now so game spec, 10k triangles max, normal maps allowed, a combined texture resolution of 2048 and alpha, lighting maps etc. It would be great if you posted some rough sketches and maybe a concept piece but remember this isn't CGsociety so we can all provide nice constructive crit and help each other along the way.

I'm okay with a vehicle since I really don't have any on my reel. I will pick up with the rest of Jeff Miller once I get off of work. Actually, I have met Andrew twice now and he never seemed pretentious to me.

I'm all for a vehicle. I'll probably do something like this: With a bunch of cloth so I can practice my sculpting, unless someone has a better idea for a military vehicle with cloth. I really don't care what we do so long as I can shoehorn in learning zBrush since I need to do that. cubicle I'm not sure what you mean by "hard object" - if you mean difficult, there are certainly difficult military machines out there. And most of them are not soft-surface models
