Sharing our progressive morph Script with the community

Well I’m just commenting on the idea that UE4 does not support progressive morphing when it does. Morphing is morphing so how that would be impractical in a video game? I used 3ds Max to create a series of flapping flags using cloth simulation and exported to UE4 as a progressive series of morphs using Alembic used in a real time networked based game. No magic it’s old school vertex animation.

Granted more tools the better.

By the way FBX does support point cache data, which is an Autodesk feature, and my guess why Epic chose Alembic.

Sure you are right in that case.

I mentioned it can be used for Debris or such assets these include flags and other similar one time or loopable FX, but I mentioned Alembic or point cache in general is pretty much impractical for game characters, which is why we still use bones and skin + Morph :). Progressive was never meant to be vertex animation simply to have better control over morphs on a skinned character in UE4.
For vertex I would even try to avoid alembic and try to use material vertex bake when i can (granted its got limitations with polycount) but Alembic has been so buggy and slow in UE I am scared of using it in production unless I must.

I think Epic is dropping FBX in the future and going all out USD for everything. That would be a great choice once all programs start supporting it and unifiying their formats like this.
