Is it more performant to animate vertex by mask or by vertex color? Asked chatGPT:

I asked this question to chatGPT and it told me this:

Is that accurate? Is VAT the best option in general? I thought using a mask or vertex color could be cheaper.

I guess you would have to look at the cons of VAT.

You would probably need a separate texture per level of detail (different vertex order / amount). These would have to reside in memory for it to work during LOD swaps.
