Animation performance drop by translation/rotation

[brunobg]

Sorry, can you clarify a couple of points please?

First you wrote:

@Deltakosh

When you animate the root meshes, you are updating their world matrix and then all their children and the children of their children need to rebuild their world matrix

Then

@Deltakosh

Well you should NOT animate the root nodes but instead the root mesh for your manta ray

So is the root node or the root mesh that I should animate?

I understand that instantiateModelsToScene returns a list of root nodes which may or may not be meshes. Is that correct? Is there an automatic way to find the root [mesh|node] (whichever is correct) automatically? I assumed whatever was returned in the .rootNodes was actually the root and not something in the hierarchy, so I’m kind of lost here.

@Deltakosh

Also why are you disabling the first one? Why not just use it

I thought it had an issue with RTT if I used the original object, but apparently not, I misunderstood it. But it turns out that container.meshes have completely different objects than mantas. So what exactly instantiateModelsToScene returns? Can use the original mesh and the instances together on an array and treat them just alike, or are there any restrictions?

Thanks Deltakosh
