Baked Texture Animations with Animation Groups?

Questions

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 - afrokick/bjs-vat-helpers

How it works

  • Create a temporary scene to render VAT as fast as possible(manually call scene.render method)
  • Disable some stuff to gain more performance while rendering(like aggressive mode)
  • You only need to have any mesh with skeleton to be able to render animations into texture. So you can have a simple version of you complex model(like only a hat mesh for Character). In my game I have player_vat.gltf for vat baking(simple mesh+skeleton+animations) and player.gltf for rendering(all meshes + skeleton).

Thank you @Evgeni_Popov for your help with VATs. Now I understand it more deeply.

@oriongu You can use it in your MMO as well!

PS It would be nice to have it “out of the box” for babylonjs/core.
