Abcvfx

Abcvfx is a Unity sample project showing using VFX Graph with Alembic animation.

Previously, this repository contained a special package to support Alembic animation on VFX Graph. This special package is no longer needed because VFX Graph accepts dynamic mesh input as a standard feature in the recent versions.

"Static Texture" sample

StaticTexture is a sample scene of Alembic animation with a static texture/topology.

"Video Texture" sample

VideoTexture is a sample scene of Alembic animation with dynamic texture/topology ("volumetric video").

It uses "BMX" sample sequence from 4Dviews, but this repository doesn't contain those files. You can download them from the 4Dviews website. ¹

You can use ffmpeg to create a HAP video clip from the image sequence in the 4Dviews sample.

ffmpeg -r 30 -i BMX_%06d.jpg -c:v hap BMX.mov

Put the generated BMX.mov file in the Assets/StreamingAssets directory.
