Keeping skeleton[] in non-mesh babylon file.

[MicroEyes]

Hi,

I have 3 babylon files to test with (say SectionA):

1. Base model with mesh & skeleton (no animation): After opening file as JSON,
   1. meshes[] with respective mesh data and meshes[mesh_index].animations array as empty.
   2. skeleton[skeleton_index].bones[bones_index].animation object with just two objects in keys array with first object contains first frame values and second object contains last frame values.
2. With no mesh, with skeleton & animation: As JSON,
   1. meshes[] with respective mesh data and meshes[mesh_index].animations[animations_index] object with property and respective keys array.
   2. skeleton array is empty here.
3. Base model with mesh, skeleton & animation: As JSON,
   1. meshes[] with respective mesh data and meshes[mesh_index].animations array as empty.
   2. skeleton[skeleton_index].bones[bones_index].animation.keys[] array with frame property values.

In my case, My aim is to keep (say SectionB):

1. One babylon file with mesh, skeleton and no animation
2. One babylon file with no mesh but with skeleton and animations.

But my test is failing with #2 (from SectionA) where my animation data is not skeleton[] array and when i run below code, i get undefined in return from this.getSkeleton().

let l_newSkeleton:Babylon.Skeleton = this.getSkeleton("skeleton").clone("skeleton #0", "0");    //getSkeleton() is my function, which returns Skeleton object.
this.m_baseMesh.skeleton = l_newSkeleton;       //Replacing skeleton on base mesh.
this.m_game._scene.beginAnimation(this.m_baseMesh.skeleton, 0, 200, true);   //playing animation on base mesh's new skeleton.

 

How can i maintain skeleton[] array with animations in non-mesh babylon file, while exporting?

 

We are using 3DsMAX 2013 and Exporter_version is '0.4.5'.

Can you share a file from #2? I'll see what I can do

Hi @Deltakosh,

Thanks for contacting back.

Please find attached ZIP file with "son.babylon" as base mesh and "[email protected]" as animation file.

But [email protected] have empty skeleton and animations are in meshes[mesh_index ].animations[animations_index] object with property and respective keys array.

My expectation is to use [email protected] to keep only animation and skeleton data (no mesh information), assigning skeleton to son.babylon and play animation, it should get played.

Just to make sure: Why not just keeping a dummy mesh root to host your animation data?

Apologies for the delay in response. We had a project delivery to make.

I don't want to download two babylon files with same mesh data.

In my case, i want to download base mesh babylon file with T-pose at start and download animation babylon files on demand or depends on conditions at every stage in my project. On the other hand, downloading mesh data with each animation will make the size of each file larger and its also not good to keep duplicate & unusable mesh data in memory.

I meant a dummy mesh like a simple cube

Thanks @Deltakosh. Let me try and get back to you with results.
