Hello, I’ve tried working with the Baked Texture Animations feature in 5.0, and there doesn’t seem to be a way to bake Skeleton animations with Animation Groups (coming for example in a GLB file from Blender). There seems to be some discussions around the topic, and all the examples on the docs an…

After spending a couple of days I’ve finally figured out how to bake VAT at the max FPS. The DEMO: https://playground.babylonjs.com/#3NIXCL#688 On my laptop it requires 400-500ms to render ALL animation groups into the texture. For previous code, it was > 25sec. You can see the code here: GitHub…

With BVA, there’s no more skeleton or bones, only a texture with the list of transformed vertices for all the frames of the animation, so attaching a mesh to a bone won’t work. It’s possible to get it to work to some extent, though, but it’s a bit involved. You need a skeleton to attach the weapon…

Thanks @Evgeni_Popov for a very detailled post, however it will take me a while to digest to fully understand what is happening there.

Another way to make it work, is by skinning the weapon instead of attaching it Skin the weapon using the player skeleton, and weight all of its vertices to the hand bone. Then parent the weapon mesh to the player mesh. Make the weapon use the same VAT texture as the player mesh, as they have the sa…

I’m not sure if I understand the caveat you’re explaining: Are you talking about the animation offset? If so what would be the use case were you would want a different animation offset? Anyway, I now understand what is happening behind the scenes thanks to your great explanation and I quite easily …

Thats why any solution has its own pros and cons :grinning: VAT gives you performance, but increase complexity. With items(I think in 99%), you can add bones weight via code because all vertices have 1 or 0 in most cases. Like Sword - you need to set 1 for the Hand bone and 0 for others. Same for …

[image] oriongu: Are you talking about the animation offset? If so what would be the use case were you would want a different animation offset? Yes, it’s the animation offset. It is used (at least in the demo PG) to desynchronize the avatars and have all the walk, run, … animations to be in s…

Hi there, Sorry to bother you again, To improve performace, I’m going to have to implement VAT eventually, and I was working on updating the playground, but cannot seem to get the sword attached to my player, could you have a look? Babylon.js Playground Babylon.js playground is a liv…

The main problem is that the hierarchy of the skeleton is not the same for your character than for the character in the other PG. It seems you should use index #38 to properly attach the sword to the hand. Also: the order of the anims in PICKED_ANIMS should be given in the order they appear in th…

@Evgeni_Popov Thanks and noted. I’ve been working on using multiples entity types and animations and make it all work together following the playground example, it’s a slow progress, but I will get there :wink: [image]

Hi there, It’s me again, It’s feels a little like harrassment at this stage :wink: After quite a few tries, I cannot seem to find how to stop weapon animation from looping (upon death for example), I’m guessing I must work on lines 68-72 but I’m not clear what to do. USE W TO MOVE USE SPACE TO P…

Yes, if you are using a VAT for each part (in my PG above, the sword is not a VAT).

Indeed!
