Questions about animation

Hello Everybody,
I just have some questions ....
Is there any possibility that I can use an animation such as "aim" for the top part and then "walk" animation for the bottom part of my character at the same time???Or I have to create this animation???

Also, If I use a side camera ... how can I blend the animation of the aim so that when I move my mouse up the player aims up ((I have the animation on the Model)).... I mean I have the animation for the aim up but i don't want it to play till the end .... I want it to stop to the same extent that I moved my mouse up to ....

Thanks in advance.....

You can blend vertex animations, too, but the better choice in your situation would be to blend bone animations.
Have a look at ANM_ADD, ent_blendframe and ent_blendpose.

Thanks Superku ....
The problem is that my aim animation is during idle mode ((ie: stand and aim)) however I am trying to blend this with my run animation so that I can aim and run...
I tried ANM_ADD but the player starts showing some weird deformations because both of the animations are playing for the whole player ....
this is my problem ... I don't knw how to control the animation so that it only affect the top part....

You've only tried vertex animation, right? Vertex blending is only done for all vertices between two frames.
In your case you need to use/ blend bone animations.

yea ... I tried vertex blending
I can import the animation with bones but how do I blend certain bones ... Is there any example??? in AUM??
