I think I have made a mistake and was hoping someone can point me in the right direction. I have a setup that takes uses a particles to spawn rbd objects (from a single mesh) over time. This all works and I'm happy with the sim and have written it to disk with a file node.

Here's the BUT. But, before I did the sim I thought it would be an idea to reduce the density of my object to speed things up with the Buller Solver (was this even necessary?). I did this with a polyreduce SOP. I just assumed I could easily use the sim data on disk but with the ORIGINAL higher density geometry before exporting to Maya. This is where I'm stuck. I've checked out the ProxyGeometry example and have changed the settings in a dopimport SOP to transform the input geometry but this doesn't work, and fetching geometry from the DOP returns the lower res geo I used in the sim.

If I simply want the exact same sim but using the non-polyreduced version of the geometry how do I go about this? It seems the particle spawning is the only thing different in my setup.

Cheers,
Steve

If the group names are the same for hi and lo-rez geo, then simply plug the hi-rez geo into the DOP transform SOP and choose “transform input geo” instead of “fetch” and it should all “just work”.

Well the low-res was simply the high-res geo with a PolyReduse. I plug the dopimport node into the hires geo above the PolyReduse swith fetch to translate but it doesn't seem to work.

Haven't got it in front of me as I'm not at work now, but I'll check it with a simplified scene when I get a chance.

You have to plug the hi-rez geo into the DOP import, not the other way around.

To check you have the same groups, in both, use a blast to delete any one group in the low-rez. Then plug it into the hi-rez. Is the same object deleted? If not, you have a problem.
