Hello guys,
I looking for a solution to play complete animation over other animations. For example, shoottingAni affects the upper half of the body(only keyframes from Spine bone) and runAni in the background.
I tried some ways:
Set runAni.setEffectiveWeight(0) and shoottingAni.setEffectiveWeight(1) => upperbody ok, but bottombody reset to default pose.
Set runAni.setEffectiveWeight(0.1) and shoottingAni.setEffectiveWeight(1) => bottom body ok, but upper body blend together makes the wrong animation.
Change transform of bones following shoottingAni. I write some code on the update function(after the update animation) for the change transform of bone. This way looks doing the right way, but the animation is not smooth, I can continue working with tween to make it better but I see that FPS is down from 60 to 35 after running this code, and not back to 60. I canât understand why. Maybe because call âgetBoneByNameâ too much?
âTHREE.AdditiveAnimationBlendModeâ Apply this blend mode to shoottingAni, and everything transforms of bone looks like âAdditionâ. But I want to âReplaceâ.
Thanks for any suggestions and ideas, I really appreciate any help.
Not 100% sure if I understood correctly - but if this is the kind of effect youâre looking for (legs and aiming moving independently - then after loading your animations, you can just filter the bones to which said animation will be applied (ex. aiming animation only to top body, walking only bottom body, idle animation to both etc.):
if (filterBones) {
// NOTE Run animation only for these specific bones
const filteredBindings = [];
const filteredInterpolants = [];
const bindings = action._propertyBindings || [];
const interpolants = action._interpolants || [];
bindings.forEach((propertyMixer, index) => {
const { binding } = propertyMixer;
if ((binding && binding.targetObject && !filterBones.includes(binding.targetObject.name))) {
return;
} else {
filteredBindings.push(propertyMixer);
filteredInterpolants.push(interpolants[index]);
}
});
action._propertyBindings = filteredBindings;
action._interpolants = filteredInterpolants;
} else if (excludeBones) {
// NOTE Run animation for all except these specific bones
const filteredBindings = [];
const filteredInterpolants = [];
const bindings = action._propertyBindings || [];
const interpolants = action._interpolants || [];
bindings.forEach((propertyMixer, index) => {
const { binding } = propertyMixer;
if (!(binding && binding.targetObject && excludeBones.includes(binding.targetObject.name))) {
filteredBindings.push(propertyMixer);
filteredInterpolants.push(interpolants[index]);
}
});
action._propertyBindings = filteredBindings;
action._interpolants = filteredInterpolants;
}
The filtering then has to be done only one time, when the animation is loaded.
Beautiful, Itâs exactly what I need. Thank you so so much <3. Just note that I canât find âtargetObjectâ in PropertyMixer(my version is r149), so I used 'binding.node.name' instead of 'binding.targetObject.name'
Could you show how were you able to play both animations at the same time? I was able to remove the lower half bindings for my âaimâ animation, so the legs are now unaffected, but this just makes my characterâs lower half in a T-pose.
