HOW TO USE IMPORT PARTICLES IN ALEMBIC
1 / import alembic (do not forget in preference - cogwheel - check "is sequence") 2 / create an object that will be instantiated (which will replace the points)
3 put a material on this object
4 size very small this object
5 select this object - shift select frame 1 of the alembic (in the viewport select the very beginning of the alembic - the first stream of particles)
6 / click ctrl + P - parent to object
7 select only particles (frame 1 of the alembic) (in the viewport select the very beginning of the alembic - the first stream of particles)
8 / click object properties (orange square) / instancing / Verts
IT'S OK - animation and eevee rendering and cycles
