In this second set of videos, you will learn how to use CAT to animate. You'll see everything about the animation layer manager and the types of layers that CAT offers. You will also go through some techniques for using CAT Motion and the Target IK system.

CAT Animation Layers

In this video, learn the basics of animation layers and how layers relate to each other in the layer evaulation stack.

Types of Animation Layers in CAT

CAT offers 4 types of animation layers that all have a special use in animations. In this video, you will learn what are those types and what you can do with them.

Introduction to CAT Motion

CAT Motion allows the creation of procedural walk cycles with attitude. In this first introduction to CAT Motion, you'll see the workflow to create in place loopable walk cycles.

Making Characters Walk in a Scene with CAT Motion

Extend you knowledge of CAT Motion to make your characters walk (and run!) in a scene by having them follow a animated node or a motion path. All that while the footsteps are sticking to an uneven ground without sliding. See how the same technique is used for bipeds and centipedes.

Overview of the Target IK System

CAT has a unique Target IK system that allows to have the character's hands or feet follow an object in a scene. In this video, see how the Target IK system works.

Animating with the Target IK System

In this video, see how the Tarket IK system of CAT can be used to have a character walk on its knees and how to have the hands of a character rest on his legs (hands in pockets) then on his pelvis (fashion show walk).

Mixing Layers with Different Transition Positions

When you mix animation layers together, it often happens that the end position of the ending layer doesn't match with the position of the starting layer. CAT offers a nice workflow to adjust relative positions between layers that don't match. Learn how it works in this video.

After doing this second set of videos, i realized that their is still a lot more to cover. So i'll be recording new videos and will post them here soon. So, check out for CAT Overview Part 3.

Using 3D Studio Max 2015, in the walking on knees tutorial, starting from 1:30, after rotating the lower legs upwards, the lower legs will stay in position as the knee swings; instead of conforming to the ground. How do we fix this?

Dear Louis

Superb tutorials. I learned most impotent concepts with your videos.

Thank you very much for your great effort.

The CAT rig is so easy to use. The last tutorial was great. I can't wait to see more. I hope next time to see some MOCAP in the next Tutorials.

Great work.

The tutorials are good, but the video quality is pretty terrible. A higher resolution, better codec, higher bit rate, or a combination of those would be great.
