Multiple Objects sharing Mesh with blend shape (Shape Key) Flicker.

MagicMike

When I have multiple game characters sharing the same mesh, but with different blend key values they all visually flicker between each others values for the blend keys.

I can prevent this "bug" by forcing each character to make's it's mesh a duplicate of itself upon load, so that they are not all sharing the same mesh.

However this is causing the scene loading to be extremely slow.

Does any one else have experience with multiple objects sharing the same mesh with blend keys? Is there anything I can do to speed up loading time?

Also... There isn't much documentation on Blend Keys. This feature is here to stay right?

Thanks! It's an exciting time to be working with Godot :)

I've been messing around with this more, and the above work-around is still required, but you can at least speed things up by assigning your morphs to a smaller vertex group if they only modify part of the mesh.

Also, creating a function to load in/instance the actors more dynamically in another thread might help too, but you could end up with actors visibly popping in to the game world. Then again it should be possible to create a sort of a fade in effect like many other games do.

That's a good idea. I got some kind of huge efficiency improvements from either a graphics card update, or newer version of Godot, or something and I'm back to instant loading, but I will definitely do dynamic loading if things slow down again. Thanks!
