Gargoyles Modelsheet

2008-04-04T00:34:00.001-07:00

Not much work to make the female version of this too, so why not? One of these days I will stop obsessing over wither or not the models are 100% quads on the base mesh.. anyway.

Updated: work in progress model.

Goliath character from Gargoyles has some cool rigging challenges. I'm not sure how far I will get with this project, but drawing a modelsheet is a start...

More Yosemite

These are some panorama photos from a recent trip to yosemite. I composited them in photoshop, from about 11 shots.

Scale!

2007-09-09T23:50:00.001-07:00

I'm always told its good to include a human for scale, in visual development work. Just to how big is "El Capitan" rock face in Yosemite Valley , California? See if you can spot the rock climbers in this inset shot . You will need to zoom in. Hint: look for the climbers' human shadows.

Yosemite Trip

2007-09-09T23:41:00.001-07:00

Update: I painted in the missing trees at the top, and fixed the edge seam.

Some rough cuts of some panoramic photos I took on my recent trip to Yosemite. If I find time I will take out the seams. I'm told there is software that can also do this automatically, but all I'm using is photoshop. I had issues with the yosemite falls swinging bridge photo because I had the camera on auto exposure which means I had to manually match the difference in exposure for the photos. I've gained new appreciation for how much the eye automatically adjusts for contrast, its one of the reasons that the values always much more visually appealing in artwork compared to straight photography. It is also one of the reasons ala prima painters insist on painting on location.

Troll Facial Muscle Test

This is a mocap rigging demo I did from a tutorial in the art of rigging 3 by CGItoolkit.com. I formated the human facial structure to my own model of a the Lord of the Rings "Cave Troll". The animation is provided by motion analysis. http://www.youtube.com/user/cmarsArtist

This is some traces from photo reference I did to try and to get a feel for the range of motion in the face, as well as possible poses for the character. Where the edge loops will go, and how much of that will actually follow the muscle structure.

Model, UV, Texture by Claire Marshall
Light rig By Ken Brose

The conversion of the mud box normal map didn't look so good, becuase I departed too far from the original geometry for it to look nice on the low model. So I went ahead and painted a traditional bump map in photoshop. If I was to do it again I would have painted over photo reference instead of trying to render out every last bit by hand. I think John Clapp would be proud of the rendering on this thing. I really went through a lot of effort to make sure the back "rocks" scaled in size as they got further away from the spine. I'm not sure if the blood spatter stain works or not, I might move it up across the chest becuase right now it draws too much attention away from the face.

Mubox work in progress

I would keep working on this more tonight but its 4am and I've got a trip to london tommarrow. It should be exciting!

Troll Mud Box Preview

2007-03-19T02:17:00.000-07:00

Troll top view in mud box. If you want photo realistic textures in mudbox you can stencil a b/w image straight on to the model. Personally I like to paint it all by hand becuase I have more control and I can work looser. Pasting reference in seems like to cheep a solution, its too obvious were the photo ends and hand paint begins.

There is more than one way to skin a Cave Troll.

2007-03-10T00:25:00.000-08:00

There is more than one way to skin a Cave Troll. Dave specifically asked for a "pelt map" with as little seams on the Cave troll's back. He also wanted to see as little texture streching as possible while still making effecient use of the UV space. I spent probably wayyy to many hours on both of these but I think it payed off as far as I know know how to get the UV editor to do exactly what I want, instead of just guessing as to how it will unfold.

One problem I encountered was that The UVs kept blowing up after I used the unfold command on a mirrored UV. I realized that it was probably having something to do with topology getting reversed. I used the Unfold comand on the entired UV shell and that fixed the problem. So besure to check that your UV maps are flipped on the correct side if you want to connect to together. A second issue with unfolding is that the maps tend to fold over in the corners. If that happens use the relax command on the offending area and it will sag the UVs on the seam and square them up in the inside. Then select one half of the sag and unfold it. Then select the other half. This method is pretty good for a quick fix as opposed to manually pulling the uvs out of each other one by one.

I think it might be worth it to write up a tutorial on my methods for my own reference as well as for the other students, becuase I know a lot of people who could use more help on UVs. For example there are a lot of Newbie mistakes in the troll pelt map that I didn't know I had made until I showed it around to some professional UV mappers.

A good UV map should have perfect symetry. It should also make use of the space and have no overlaping UVs. Areas that require more detail such as the head and hands should be larger on the UV map than areas of the model that are mostly flat and uniform. All the UV squares should ideally be as simalar in shape as the modeled geometry. The UV map should have as few seams as possible. Seams that are on the model should be located where they will be seen the least such as under the foot and on the interior of the leg. If possible try to make UV map seams a straight edge or a clone of the opposite edge so that it is easier paint the seam edge in Photoshop. Excessive stretching of the texture is not desireable. Its not really possible to create a UV map that doesn't have at least some bad areas in it. Don't attach to hard and fast to these suggestions in the end what matters is how it looks in the final in game art.

More LOTR Cave Troll Progress

2007-03-06T19:22:00.000-08:00

I went back and changed the edge loops so that they follow the contours of the Face and muscle structure. The right side is the new side and the left side is the model from last post, for comparison. I am really happy with how much progess I have made on the detail of the eye rim. I have learned a lot from trying to create models from professional grade designs. Its really clued me in to the level of detail present in professional work that I wasn't getting from working from my own designs. If I had the time I would work this to a point were it looked exactly like the original design, but for now, I think its close enough. I should start on to UV mapping, texturing and mudbox by the end of the week.

weighting Pose Pass - Troll

2007-03-05T04:48:00.000-08:00

Cave troll with test Rig and quicky paint weights. My Maya instructor suggested that I test the deformations on a model in a pose to see if it looks how I wanted becuase it can be difficult to preconcieve how a model will look in standard T pose. I included a photo of the Cave troll Maquette reference, which is done by the Lord of the Rings movie staff not by me. I am taking a Maquette class. Im not sure if I want to do a cave troll for that too but I would look kinda cool to see the whole process in portfolio.

Lord of the Rings cave Troll, based off a photo of a LOTR maquette. I have gone through a few design revisions on this one. This latest one has lots of hanging fat and more upper body muscles.

Adding some more details. I hit the 4000 poly limit on the nose, with the medium Res. Now Im going back in to add details to a high res Sub-proxy. I should probably be UV mapping right now but I really prefer to not be editing geo when I UV becuase it is very unpredicitable.

Three Cheers for Mudbox

2007-02-13T01:22:00.000-08:00

I just got mudbox on a recommendation from my 3d instructor. Wow! where has this software been all my life? I made this coral from in about 20mins from a cube, to do it in Maya would have taken considerably longer. Mudbox lets you sculpt with a tablet paint stlye, although its not good for creating extruded geometry it is amazing for adding surface level details.
