-“You have to consider channels as part of the skeleton that are animated. The default behavior is to use the whole skeleton for a channel.
 In your example the first channel plays the walk anim, then the second channel plays the dodge animation.
+
 Arms and feet are probably not affected by the doge animation so you can see the walk anim for them, but the rest of the body plays the dodge animation.
 
 Usually multiple channels are used to animate different part of the body. For example you create one channel for the lower part of the body and one for the upper part. This allow you to play a walk animation with the lower part and for example a shoot animation with the upper part. This way your character can walk while shooting.
 
 In your case, where you want animations to chain for the whole skeleton, you just have to use one channel.

 == Transparent Unshaded Texture
 
-`Monkey.png` is the same texture as `Monkey.jpg`, but with an added alpha channel. The alpha channel allows you to specify which areas of the texture you want to be opaque or transparent: Black areas of the alpha channel remain opaque, gray areas become translucent, and white areas become transparent.

The alpha channel allows you to specify which areas of the texture you want to be opaque or transparent: Black areas of the alpha channel remain opaque, gray areas become translucent, and white areas become transparent.
 
 For a partially translucent/transparent texture, you need:
