Hey guys.. so I'm very new to Houdini, and I made a FLIP tank anim with an awesome tut (https://www.youtube.com/watch?v=DlDvsygqoc4&t=309s)

But I can't render this cool sim! I assigned a RS material to the tube I instances with copy to points. Any help would be greatly appreciated!

You have to give the OBJ container redshift "OBJ properties".(find them in the redshift toolbar)
in there under instancing check "Instance SOP level packed Primitives"

Cheers

Also don't forget to enable the "Pack and Instance" option on the copy to points node.
