You can get round the tiling path not being the same as the grass by a double blend strip if you really want to. Or do it all with multiple images on the same material.

Mutata's got it. You can even see that the edge strips are mirrored and tiled along the sides. They're probably also adding vertex color to blend the edge, too. On the ground plane, they're most likely just blending out from a tilable grass texture, into edge strips with hard alpha on top of a tilable dirt texture.

gently caress! gently caress!!! I thought I had it and was about to make a mockup later. I just woke up to great news of another reference image.  I now once again am back to square one. The only seam I notice on this one is  But I absolutely do not understand how you could model that in the slightest  Edit: vvv Care to point out which details are on what plane?

There's a bunch of bad cuts around the grass, although some of that might be jpg artifacting. To the left of the character with the gun on her butt in the bottom right, there's a cut in the grass. What I think they've got going on is this: Two materials (maybe a third). A grass material. This uses 2 UV sets - 1 to tile a green grass tile at a natural tile across the mesh, and a second UV set to wrap a grass-edge 'ribbon' around the edging of the path. The grass ribbon texture uses alpha so it looks like it sits on the grass. The bad grass cuts around the edges of the grass are where they're loving up their vertex blending. It's a simple LERP, nothing blending with heightmaps or anything fancy (or maybe I'm wrong and they're using a heightmap or alpha to modify the vertex blend). A dirt/stone material. This uses 1 UV set, and tiles the two textures in teh same dimensions. The stones are using an alpha map to let them sit with hard edges, but then they're blending in dirt over some of them. If this is using heightmap-based blending they can get some very nice transitions between dirt/stone, but it doesn't look like that to me, they look like lerps and they're probably just adding extra verts to get tighter blends. There's probably better tutorials but I don't give a gently caress at the moment, so here's my first google search for a tutorial on the concept (albeit in a different application http://eat3d.com/free/vertex_painting )

In 3d, sometimes its best to just start making something and testing, you can over plan trying to get it right first time and you seem like you're reaching that point. create a couple of tests and stop being afraid of ever doing something you'll have to throw away, its part of the process. Get some colored checkerboard maps and see how it works in practice, it'll be much easier to resolve what's happening when you're not trying to visualize every possible situation in your head.

Is it possible that the edges of the grass are just being eaten away by fractal noise or something similar? So it's just one layer of dirt, one layer of grass, and one layer of black+white that defines the path which removes grass and lets the dirt show through. Define a spline "path" to take through an area, widen that path 50-100 pixels or so, blur+fractal noise to roughen up the edges, and that is your alpha to erase grass. Do this twice though, once dark and once light (with slightly expanded/contracted settings), so you get a bit of a shadow effect where the dirt touches grass. Seems like a shader should be able to do something like this. I'm tackling it like a 2D problem in After Effects though.

Do this twice though, once dark and once light (with slightly expanded/contracted settings), so you get a bit of a shadow effect where the dirt touches grass. The edges on the grass have highlights. Also generally shaders that complex aren't very good for games. Anyway, you still end up storing the same texture size in memory if you do it that way and memory is the problem, not disk space.

Again, polys don't just exist in places, you put them in places for a purpose.

It's a really impressive little tablet but look into the Wacom Companion since it has the buttons on the bezel. I've had to build my own little CTRL ALT SHIFT thing out of a cheapo $10 keyboard since I got tired of constantly remapping the single pen button. It's pretty cool being able to pop out a tablet on a streetcar and start sculpting millions of polygons but I am by no means a professional Zbrush guy. bring back old gbs fucked around with this message at 21:40 on Nov 9, 2013 |

Yea not interested in the companion because it is way overpriced for what it is. I can get a small game controller keyboard thing from logitech to have on the side for zbrush and others. Do you get any brush feedback lag on your surface with zbrush? I only tried sculptris on it and it had a short delay before the brush started deforming. Dunno if that's a sculptris thing or a surface pro limitation.

Zero lag in my experience. I don't go easy on it with efficient base meshes either, I start with a dense as hell dynamesh ball and increase the polycount from there. I have 4GB of ram in mine and gave Zbrush access to 3 of that. I think with the Surface 2 you can even get 8GB of ram but you're looking at Companion prices at that point. There is a bit of weirdness around the corners where the stylus alignment gets screwy sometimes but it's better with the 2 apparently. Everything aligns perfectly everywhere else. I'd also recommend Wacom's feelIT pen that works on the Surface since it has replaceable tips and apparently the stock pen is recognized by the digitizer slightly higher than the actual tip. Inside the body of the pen itself. Wacom's pen is sensed by the screen right at the tip. Personally I never had a problem using the stock pen but I switched anyways for the softer nib. It sucks Microsoft has no idea how to market this thing. Every display model Surface should have some gimped version of photoshop and zbrush installed. If you're looking for extra keys look into a Razer Nostromo. They're pricey but you can customize it to hell and back. Hold it upside down so that you're looking at the rubber feet on the bottom and rest your surface on that like a paint palette. EDIT: 1024 levels of pressure, same as a last-gen intuos I believe. I really should be getting paid by MS for my surface shilling. I just think they're neat for this exact specific thing. bring back old gbs fucked around with this message at 06:55 on Nov 10, 2013 |

Oh nice I had no idea those Feel pens worked with it. Do you know the level of pressure sensitivity that has? I can't find it on the Wacom site. Also went to buy a surface pro 2 today after reading your post but they were sold out of the 256gb version

Those are cool Ceebee I think with the Wolverine one, while I know it's comic book style, it might look nice if you bring down the intensity of those forearm flexors. They seem to be a little uniform along their length. It might be just that they form a bit of a pattern with the striations in his pecs and will read better when printed.

Thanks guys. Yeah they're all pretty heavy WIP, the wolverine is going to be posed a bit better. It's based off of a Joe Mad version of Wolverine so he's a bit exaggerated anatomy-wise, but I'll fix the forearms fosho.

Agreed on the uniformity. Both width and length. Mixing in some thick stalks with the thin sinews would actually make him look tougher, I think. Still, top notch stuff!

Those zbrush models look ridiculously good guys! For those of you familiar with rigging: This term I am teaching another rigging class. I would like to try and up the "fun" factor for something which can be very complicated and tedious. Does anyone have a favorite "fun" rigging exercise? I will have to rig a character for the class, of course, but I can come up with small labs and exercises which illustrate a variety of rigging concepts throughout the term. In the past I have done a little intro to ncloth or dynamics but I was wondering if you guys had a favorite rigging demo or fun trick? This term, I thought I might tackle ropes and chains, or maybe something which shows switching constraints / weapon swapping from hand to hand. Not sure yet. What do you guys think? Any favorite rigging tricks / new work arounds? Any simple but effective techniques for making character rigging a little less tedious? Other than using a 3rd party plugin I mean. (example: http://www.lbrush.com/) Oh - this is in reference to a Maya class BTW.

Squash and stretch stuff is usually pretty fun. You could show how to set up a set driven key with a squash deformer so that the character can get pretty crazy shapes. Also linking nodes to create stretchy arms and legs, and how spline IKs can be great for moving tails and tentacles. And the new heatmap skinning feature in Maya does a pretty awesome job, so you can show how much easier skinning has gotten. But yeah, rigging is kinda painful and confusing. I know I tend to zone out when being lectured on it. It's only when I go back and rewatch the videos and do the exercise step by step on my own time that I can really understand and appreciate what's being done. Then after a few times it sinks into the brain.

Quick troubleshooting question I can't seem to solve. In Maya 2014, with mental ray, I'm having trouble getting transparency on a bee wing. I can see the body through the wing, but where the wing is against a blank background there is no transparency. And there's nothing in the background that's should be blocking it. Alpha channel is correct all except fro the wing part.

Forti posted:How does Maya stack up on the Surface 2? I'd get a regular 15" laptop for Maya/3Ds Max. The pixels are packed pretty dense on a 10" 1920x1080 screen and all the little buttons are even tinier. It's forgivable in Zbrush/Photoshop because of the pen and pressure levels let you do amazing things, so little annoyances are easier to overlook. It will just be all frustration all the time using a traditional 3D package on that screen. The processor can handle it though.

The cintiq companion is SOOO much more expensive for almost the same thing. Ccs: Sounds like you are describing making a potato sack rig, or cartoony limbs. Hmmm. I will have to look into the heatmap thing. Interactive Skin binding really messed up the class workflow, so I am always hesitant to try brand new tools. Stretchy bones could be fun though, and something I have been meaning to do in class. BonoMan: Did you try using Blinn material? Or are you limited to a specific material?

There are at least two ways of doing it that I know of. One: Feed a black and white image into the refraction transparency channel. Two: Feed a black and white image into Advanced -> Cutout Opacity. There may be another way, but those are the two ways I just tested and they work for me.

So it is that time again where I ponder the question that is: Should I ditch 3ds Max which keeps getting worse with each iteration for Maya? At least the Character Animation Toolkit keeps breaking for me. Figured I should pick up Digital Tutors and start fresh with Maya since from what I've gathered over the years that I have sort of been animating, is that Maya is better for animation and not relying on CAT would be good so that I can learn real rigging.

Hmm I think Bill's nose is actually a bit shorter than in your sculpt. And if you move the nose up the mouth should probably be moved up too. Also I'm getting a weird sense of his jawline, looks a little too long.

It's a real shame there isn't much online documentation for Houdini. I did a six week course in it a year ago but it was very much the basics of everything. Some in-depth destruction workflows would be great, does anyone know some good places to learn? Digital Tutors have a pretty good shattering one but most of the other Houdini tutorials are out of date.
