Tutorial: Rigging, Mechanical

I've started thinking about modeling robotic characters in the future, and how they can't be rigged exactly the same as organic characters. Organic characters need to be able to bend and change shape, but mechanical objects shouldn't (usually). These tutorials show how to rig a mechanical arm, and should suffice with rigging any mechanical character or object. This tutorial was done in Blender 2.5, but the theories should apply to 2.49.

One thing to remember, these tutorials assume each mechanical part is a separate object. If you designed a robotic character, most likely, you'll want all objects to be separate meshes in a single object, and you'd need to weight paint each bone to affect each part in the same way.

Key points:

PART 1
Creat Armature
E = Extrude Tool, extrude new bone from previously selected bone
Shift + S (while end of bone is selected)/Selection to Cursor = to move the endpoint to your previous selected vertices.
Clear Roll = once armature is finished to clear any unnecessary rotations for each bone (17:40)
Add Constraints to lock down certain rotations and location of each bone (24:50)

PART 2
Create IK Constraints

Tutorial/Reference: Texturing Casey Jones

I thought it'd be handy if I documented some of the steps I take when texturing a character. Click on any picture to see a larger version. Keep in mind, there's many steps in between. I often have to try different highlights and reload it to the character to make sure it works. These are the major steps.

Step 1. Color blocking
Here's where I go through and put down solid colors. When you apply it to your character, it's going to look like CRAP. That's because there's no lighting or details.



Step 2. Basic shadows and highlights
Some games utilize lighting, others don't. I like to paint in my lighting directly on the character. And I usually paint as if the light source is from above. I take liberties with that rule, though. If something needs a bit of highlight, I try to go for it. It's amazing how much better the character looks with some subtle gradients hinting at a light source.



Step 3. More shadows and highlights
I continue on with the process of adding more shadows and highlights. These characters are blocky by design, so I don't mind using harsh shadow lines in some places.



Step 4. Details
Here I start trying to lay down a lot of the detail work in order to further develop the character. At this point, I also start thinking about contrast, and I try to push the shadows even further. The character was screencapped before this stage of texture was done, that's why he doesn't have eyes.



Step 5. More Details
At this point, I pulled out my tablet and started painting in some clothing shadows, the kind of stuff I can't easily do with a mouse. Even more details are added.



That's where he stands so far. I have some hair to figure out.

Tutorial: Modeling

This tutorial aims at creating a character of 1800 polys.

Things to remember:
Add Loop tool = ctrl + R
Select Loop = option + cmd(RMB)
Scale selection along normals = option + S



The video is quite long so I've included time markers so you know what begins when.

Low Poly Tip #2

Here's another way of reducing polys. I'd only do this if you're never going to get a close up on the hand. Still, helpful to know, though. Model your fingers as planes, and curving them in such a way that they never appear fully flat.

Low Poly Tip #1

Going through Tom Tallian's pack of low-poly Team Fortress models, I noticed a trick he was using in order to keep his meshes low on polygons. Not everything must share the same and extend from the same points. Instead, the limbs are sometimes modeled separetely and just made to look like they are "attached". Reminds me of how action figures are assembled.

Solid Snake, Pocket Version!?

Whoa! Props to the artist of this. Additional photos/wireframes here

Reference: Yuna, FFX-2

I came across this nice little treat today. Someone extracted (I believe) the Yuna model from Final Fantasy X-2 and put it available for download. The file is a .ms3d, which is native to Milkshape3d. Unfortunately, I cannot open it because Milkshake3D is PC only. So if anyone wants to download it, Milkshape3d is free, and it might be nice to be able to check out some of that low poly hair. And if you do, any chance of exporting it to a .obj so I can check it out? (wink wink)

Here's some images, including texture maps! (256x256)!!!

Sword&Shield

This is one of the smoothest games created in Blender that I've seen so far. Though just a series of demos, this demonstrates how games in Blender can be both visually appealing and not very processor intensive.

Old School Updates

Great examples of old style games brought to 3d. I'd love see some more of these. The first is made in Blender, the second I believe in 3DS Max.

Always nice to see how the pros work. Also a good idea is how they have a character map to compare individual heights..
