random polygons removed from cluster

[angelous4x]

Hello all

I have an issues going on where I did a simulation in Houdini and bring it over to Softimage to render with redshift. there are clusters that I get from the alembic file. works fine for the first few frames but then the clusters shift. some of the polygons in the clusters shift for some reason. any idea why?

thanks

Could be it changes the id data of each poly due to bad translation in .abc file between both softs?

Maybe you can show the id for the same frames in Houdini and into SI. It keep identical properties?

Yess your totally right.
its seems that the fuse node was causing some issues. so removed it and exported it out again.

thanks for your help
