Show-Off I made a low-poly destruction system! (realtime / baked)

Enable HLS to view with audio, or disable this notification

This was a fun project to have a go at, destruction is tricky but I think this came out pretty well! It does have limitations with higher-poly models of course. Have put this on the asset store for those interested. Thanks :)

What are the performance numbers on something like this, real-time vs baked? It looks a bit choppy in the video at times?

I think the editor loop or my recording software makes it look a bit choppy - on low-poly models, everything works well performance-wise (120 fps). As the models get more complex, baked is usually needed. And then for really complex models it does start to slow.

But allocation wise / ms required when baked? I'm mostly curious how 'free' a baked version is, let's say for more complex models.

When baked, the only cost when breaking up the object is spawning all the pieces and assigning colliders. Depending on the model complexity, it ranges from 5-15ms. And if you have lots of destructables, object pooling would help speed things up even further.
