Anybody? Just want to add the rotation of my initial alembic from Maya to my fire pre-calculated in Houdini. Or another way to parenting this two elements..

I take this opportunity to ask another question: in my scene my groundplane catch some light of my fire. How can I keep just the light without the geometry of the ground? Light disappear with a matte_shading or shadow catcher..

I attach pictures for my two problems

Thanks !

It does not seem to work with this method…
My ship was animated in Maya so i don't know if Houdini have the right informations.. I can see center positions but nothing about translate, rotation or scale

My problem is surely an amateur thing. Maybe with an animation constraints or something like that?

EDIT: Center positions of my alembic give me translate animation as I suspected but my object turns on itself at the beginning. My fire doesn't follow the rotation of the spaceship. Any idea?

Hi !

I come back now on this project, others have required my attention…

Enivob your solution for the steady fire with pre-simulated flames works perfectly. But now I need to parent them with the spaceship and I don't know how to do this on the whole sequence.

Someone have a way? My object comes from Maya in alembic.


Thanks !
