how to blend two fbx animations? help needed!

daimaku

Hello i'm trying to blend two animations from mixamo in 3dmax.

i'm working on a game and i'm trying to blend the melee disarm animation into the idle animation; i ca't interplate the position and the rotation of the bones (i'm a programmer but i know a little about 3dmax), i know how to interpolate a box without bones but wheni try to do the same interpolation from the box in the mixamo animation didn't work, it only work creating keyframes on each frame and on each bone.

here is a picture of what i'm trying to do, i just need to blend the pose from the blue player into the white player, if there is a simple way to do this on 3dmax on other 3d software will be very useful.

thanks in advance for all the help.

What parts of the help file have you read so far ? I haven't worked with character rigs for awhile, and I'd defer to animators, but in lieu of one of them chiming in I'd suggest starting with something like this.

Import one fbx file. Select all the bones and do Animation | Save Animation > animfile.xaf.
Reset the file, import the next fbx file. Select the same bones and do Animation | Load Animation > animfile.xaf.
In the load dialog pick "Absolute" and change the start frame to about 5 frames past the last keyframe.

This should load both animations onto one character.

thanks for all the replys, i will try both and then i let you know how it goes.

i did that, i have both animation on one skeleton, worked without any problem, my problem now is how can i blend (make a smooth transition) from the last frame of the first animation with the begin frame of the second one ? is there a easy way to blend the two animations?

The two poses in your screenshot don't look very different. Is the 5 frame in between not a good enough blend?

So this might be over kill, but you can use the Motion Mixer to blend the two anims. Just create two XAF, then mix them together. It's a quick process when you know how, but can seem very tedious to setup on your first go round.

Here is the help page on the Motion Mixer. You can probably youtube some tutorials.

I'm guessing this is for a game engine? Why not just blend the two animations together in there?

Maybe I'm misunderstanding what you are trying to do, but from what I see this is the UE4 mannequin skeleton so I'm assuming you want to play the animation inside Unreal later. Why don't you blend them with state machines inside your game?

hello, yes i 'm trying to blend both animations to play a smooth transition in a game.

The problem is that i'm a programmer, i'm trying to make the blend between these two animations in ue4 with some blend nodes in the animation blueprint without any success.

if anyone have a good doc or tutorial to create the blend between the two fbx into the ue4, will be very useful, so far i didn't found anything.

i have found some blend docs on the ue4 site, but they didn't worked for me. thanks in advance for all the help.

It sounds like you just want a simple 1D blendspace:
