papsphilip Posted October 27, 2022 Share Posted October 27, 2022 Is there a way to reduce the filesize of this animation considering i am only transforming geo not deforming. Ideally the rop file would just save the geo just one time and then only changes in the transforms. Also can i do this with an FBX alembic.rar Quote Link to comment Share on other sites More sharing options...
haggi Posted October 27, 2022 Share Posted October 27, 2022 If you set the "Packed Transform" in the alembic "Geometry" tab to "Transform Geometry" instead of "Deform Geometry" you can save some diskspace. And don't forget to delete the unneeded attribute from the geometry. Quote Link to comment Share on other sites More sharing options...

The one i am exporting is around 5mb static alembic and 80mb animated alembic(650frames) with packed primitives and no attributes...the geometry setting set to Transform Geometry as well.

haggi Posted October 27, 2022 Share Posted October 27, 2022 I'm not completely sure what exactly is happening in your network, but as soon as you have some prim or point based animations, it will be heavy to reduce the abc filesize. If possible, you could animate points instead of full geometry and then later use a copyToPoints sop to transfer the animation. This would only work if no prims are involved in the animation.

I have made a hierarchical packing because it was needed for my project. i unpack and animate the primitives of each level. In the end i have the last level of packed primitives and i save that as alembic Quote Link to comment Share on other sites More sharing options...
