Vertex animation / physics question
Hello everyone. I have a question about the source tools- if i create a physics simulation in blender and bake it; how can i export that to source engine, if its even possible? like how valve did with the smashed hotel in portal 2; but in blender.
unless those models just have 50000 bones or something

idk, i've never looked at those models in a model viewer.

i ask because im making a p2 mod and want some detailed destruction going on in some places possibly; but i also have a crazy experemental idea of a room filling with water in a more real-looking way using baked blender water sim. although i dont think the water will work due to the vert count changing and stuff

Why not just open that model and see.

unhelpful. im asking how to export; and simply importing that model will not show me how.

I mean, you'd discover if it's vertex animated or tons of bones.

As of vertex animating, there is a workflow for Maya

i wouldnt be here if i used maya. this is for blender. but you have a point about finding out weather it uses bones. and it does not.

Those models were created with hundreds/thousands of bones. It's very complicated to set up and there is nothing in the Source Tools to help you there.

Vertex animation is actually supported if you target a recent enough engine (Portal 2 probably doesn't qualify), but it's an engine hack intended for Source Filmmaker and probably wouldn't behave correctly in a game.
