Problem and/or missing features on animation file?

Ok No problem the mesh model was loaded and it’s animating the problem is it’s animating all the Frames and there’s no option to specify the Frames range : ((

This time around, I really go to documentation and youtube tutorial and the like and every sample of animating a model needs to have a seperate animation file if you already have a huge collection of an animated mesh in a single file you have to do the lengthy process of spliting each animation frames to a separate animation file O.O which really take some time, most of game engine i’ve use in the past have this features to Unity,Irrlich,Org,XNA etc… to lessen the I/O loading and only use a single animation resources for a specific relative model.

I believe this is a must have feature T __ T other than having to specify the Current Time and Time factor

E.G:

ANIMATION:

IDLE

Repeat mode
Blend Operation
Current Time
Time Factor
Weight

Frames range
** From 1**
** To 32**

WALK

Repeat mode
Blend Operation
Current Time
Time Factor
Weight

Frames range
** From 32**
** To 64**

RUN

Repeat mode
Blend Operation
Current Time
Time Factor
Weight

Frames range
** From 64**
** To 128**
