Dear Houdiniers,

I am trying to collide moving geo with a pyro sim and I get the following in the console:

Bit wound up as I felt I was really getting somewhere with my project.
Please help if you can.

.hip attached

Thanks,

Nick.

$HIP/scraper falling geo/scraperfall.$F4.bgeo

is missing.

very big fractured geo write out. can't really upload

I have too possible wonderings about this, in my limited Houdini imagination.

1. The .bgeo files are too big for my system? each about 170 megabytes

or 2. The geo is exploding and some of it moves VERY VERY fast. Could this mess up the pyro solver?
