Hi Robert Maggie,
Is that consider to be a valid entire if we modify/incorporate/extend the houdini tool that is shipped from sidefx, for the Challenge.

work around is to convert to vdb,class fog to vdb then do the operation then convert class back to vdb to fog.

check the advanced tab, constraints values and type can be causing it.
check the collision padding inside the properties tab and make it to default, if it is high. it can be the problem
edit 2 uploaded the sample file replicating the sim. yeah as npetit said the poly reduce and the convex decomposition goes into the proxy input


I dont think u miss some attribute or miss match of attribute and causing issue from transform pieces.
I hope u will find out the solution after going through the simple file replicated setup.
