Animation problem with Yabee PView

Pipeline
1

Hi,

I’ve been using the following to make a character model and animation:
MakeHuman->Import MHX to Blender->Import BVH to Blender -> BVH to MHX armature using MakeWalk -> Export to Yabee egg

When I open PView the model is ok (apart from some texture issues which I don’t care about yet), but if I press A it says no animations. However, if I look in the egg file I can see the Bundle tag with the animation I created called “jog”.

I try to run the animation like this:

window_ = Application::GetWindow(); 
actorModel_ = window_->load_model(framework_.get_models(), "/c/Users/zobbo/dev/player2.egg");
window_->load_model(actorModel_, "/c/Users/zobbo/dev/playeranim.egg");

actorNodePath_ = window_->get_render().attach_new_node(playerNode_);
actorModel_.reparent_to(playerNode_);

//bind the animations to the model
auto_bind(actorModel_.node(), animCollection_);
bool isLooped = animCollection_.loop("jog", true);
std::cerr << "isLooped: " << isLooped << "\n";

// play an animation once:
bool isPlayed = animCollection_.play("jog");
std::cerr << "isPlayed: " << isPlayed << "\n";

Also if I do this it returns nothing:

for(int n = 0; n < animCollection_.get_num_anims(); ++n)
		std::cerr << " animation: " << animCollection_.get_anim_name(n) << endl;

This fails and returns 0 for everything, although all the files load ok. Since Pview can’t see the animation I suspect it’s an export problem, but I’ve no idea how to fix it.

Also it’s not clear to me how you load an animation that’s already in the model file in C++, do you just skip the load model bit and try and load the animation by name?

Thanks,

Cheers,

Could you share the .egg files so that we can take a look?

One thing to try is the -i flag to pview, which makes it ignore mismatching names between armature and animation. If this makes it work, then it’s simply a matter of changing the hierarchy match flags in auto_bind.

Hi rdb,

Yeah as soon as I used “-i” the animation worked. But I’m not sure what the match flags should be, it looks like it defaults to 0, I tried 1 but it made no difference and I don’t actually know what it’s doing.

I’ve put the zipped egg here: https://www.dropbox.com/s/39ns9pq1ycn5w5r/player2.egg.pz?dl=0

Thanks,

Pass PartGroup::HMF_ok_wrong_root_name to the auto_bind call, or alternatively, adjust the names in the .egg file to match up.

Yeah I actually figured it out from the pview source code. Sorry, I can’t see where else that is documented.

Alright got this working, I wasn’t applying the scale after resizing, so presumably the armature wasn’t being resized although the model was. Ah, the joys of Blender… :blush:

Also using the “separate animation files” tick box in yabee seems to resolved the naming problem with the Bundle/Dart tags.

Cheers,
