Additional Per-Vertex Data for SpriteRenderer?

Is it possible to assign additional per-vertex data streams when using SpriteRenderer? I've done the alternative method of using MeshRenderer to fake it but it's a royal pain in the ass.

 

Thanks! That seems to be exactly what I'm looking for. Will try.

 

After some testing I notice that this adds extra data to the sprite instance data. Whe I have multiple sprite renderer on different objects that referene the same sprite, to allow for different extra data, I must cache the sprite inside the object script. It works but it really strains the GPU for some reason, a lot worse than my previous MeshRenderer version. Any way to solve this problem?

 

After further investigation I don't believe batching is the main reason, but still the slow down is very obvious. I expect there to be some slow down but this seems too much to be right. Maybe behind the scene cpu to gpu memory stuff is messed up this way?

Local sprite instance caching enabled, gpu is really slow. cpu is mostly waiting for it.


sprite caching disabled.

 

Attaching the relevant code. Though not complete, should be pretty clear what I'm trying to achieve.

 

Bunmp. A critical performance blocker. Please help.
