|---|
| 10 | |
|---|
| 11 | This tutorial shows how to export a basic skeleton from 3D studio max 5. |
|---|
| 12 | |
|---|
| 13 | <H4> Create the scene </H4> |
|---|
| 14 | <UL> |
|---|
| 15 | <LI> |
|---|
| 16 | Create a Box with several height segments in the perspective view.<BR><BR> |
|---|
| 17 | <img src="images/intro1.jpg" /><BR><BR> |
|---|
| 18 | </LI> |
|---|
| 19 | <LI> |
|---|
| 20 | Add bones in the front view, in order to be able to skin this box. Here I change bones height and width to 20...<BR><BR> |
|---|
| 21 | <img src="images/intro2.jpg" /><BR><BR> |
|---|
| 22 | </LI> |
|---|
| 23 | <LI> |
|---|
| 24 | Add the skin modifier to the box and attach the bones which have just been created.<BR><BR> |
|---|
| 25 | <img src="images/intro3.jpg" /><BR><BR> |
|---|
| 26 | </LI> |
|---|
| 27 | </UL> |
|---|
| 28 | |
|---|
| 29 | Now, if you move or rotate the bones, the mesh will 'follow' them. |
|---|
| 30 | |
|---|
| 31 | <H4> Bones animation </H4> |
|---|
| 32 | In order to animate the box, let's create some keys in a trackview ("Graph Editors/New track view"). Another way is to 'play with the setKey button. |
|---|
| 33 | <UL> |
|---|
| 34 | <LI> |
|---|
| 35 | Select Bone02 for example.<BR> |
|---|
| 36 | Create keys at frame 0 and 20 in the Z rotation track and move the one at frame 20.<BR><BR> |
|---|
| 37 | <img src="images/trackview1.jpg" /><BR> |
|---|
| 38 | Do the same thing for another bone and another axis...<BR><BR> |
|---|
| 39 | </LI> |
|---|
| 40 | <LI> |
|---|
| 41 | <B>Exporter uses the controller tracks in order to know when it should set animation keyframes.</B><BR><BR> |
|---|
| 42 | </LI> |
|---|
| 43 | <LI> |
|---|
| 44 | <U>The last thing to do is applying a material, or you will not be able to export.</U><BR><BR> |
|---|
| 45 | </LI> |
|---|
| 46 | <LI> |
|---|
| 47 | Now, the box can be exported by the exporter. Select it, uncheck "export texure information" because Texture coordinates have not |
|---|
| 48 | been generated by UVWMap modifier for example, and there will be an error if you try to export. Write the animation name you want, |
|---|
| 49 | but it must be the same as the one you use in your OGRE application (look at the SkeletonAnimation Demo if you want a sample). |
|---|
| 50 | </LI> |
|---|
| 51 | </UL> |
|---|
| 52 | |
|---|
| 53 | But a great feature would be to export Inverse Kinematics... It's possible ! |
|---|
| 54 | |
|---|
| 55 | <H4> Inverse Kinematics </H4> |
|---|
| 56 | <UL> |
|---|
| 57 | <LI> |
|---|
| 58 | Select Bone01 and go to "Animation/IK solver/HI solver", now select the last bone. This step creates an IK Chain. |
|---|
| 59 | <img src="images/IK1.jpg" /><BR><BR> |
|---|
| 60 | </LI> |
|---|
| 61 | <LI> |
|---|
| 62 | You can animate it with its track view, with a spline as a path or anything else you want. But there will not be any keys in bones controllers tracks. |
|---|
| 63 | And... if there is no key, there is no animation. Just add them in a track view. You can use the controller and sub_controllers you want |
|---|
| 64 | for Rotation and Position, just choose a track and add your keys. Do that to all the bones. |
|---|
| 65 | </LI> |
|---|
| 66 | </UL> |

| 67 | |
|---|
| 68 | <BR><B> That's all ! Have fun with this exporter !</B><BR><BR> |
