Animations messed up

[Alienhead]

The same process I have used since day one with Ultra no longer works and has rendered all my animations entirely useless. 

When importing a mixamo animation into the editor -- i now get this.

I recall awhile back some people mumbling about the system not working when in actuality it worked flawlessly but was being used wrong., I can only assume you followed up on  their complaints and decided to correct it when in reality it now appears to be broke as far as everything i created since my first day of beta. 

The process is simple, I export a model out of mixamo in tpose..  i then export an animation sequence out of mixamo and Load Animation in the editior.  The above pic is the new results.

Could be related to recent changes how models now loads (for faster loading)

Even models I havent touched  and worked fine a few weeks ago. now look like this when animating.

Same for me. Converted model for testing can be found here: https://github.com/Dreikblack/CppTutorialProject/tree/master/Models/Characters/Paladin

Hi, can you please provide a model file in its original file format that does not work correctly?

[Alienhead]

Base + one animation sequence, original format.

I think I know the cause. I removed bone scaling when loading files from the Leadwerks 4 model format to fix this problem:

But it looks like that is causing more serious problems.

Here is what your model looks like when I add bone scale back into animation keys.

I have updated the editor now. If everything works in there then this fix will be included in the next update.

I just imported 4 anim sequences into the editor and the base model seems to take them just fine, everything is looking normal that is.

That is, with newly converted mesh.. Everything prior to new conversions is messed up.

But I suppose we'll just have to live with that, being beta and all.

 

[Alienhead]

Hold that last statement..   It's fine when  I Load Animation into the model, but when I save the model then load it back up.. its whacked again.

 

[Josh]

I am seeing the same thing.

There are two different versions of the MDL format, so if you save the MDL after conversion, you are saving it to the new format. Apparently there is some problem in that, but I am not sure yet where because the saving the loading code both appear to be including the animation key scale...

I'm sure I will figure this out but it will take some more time.

[Josh]

I'm going through all the bone data on the original and resaved models. So far everything matches up perfectly. Will continue looking to see where the error is...

@Dreikblack wins the prize for best clairvoyant debugging. (The boneindices elements are each an unsigned char.)

mesh->m_vertices[v].boneindices[0] = stream->ReadShort();
mesh->m_vertices[v].boneindices[1] = stream->ReadShort();
mesh->m_vertices[v].boneindices[2] = stream->ReadShort();
mesh->m_vertices[v].boneindices[3] = stream->ReadShort();
//stream->Read(&mesh->m_vertices[v].boneindices[0], 8);// No, no no no! https://www.leadwerks.com/community/topic/68279-animations-messed-up/
