Hi everyone,

I recently finished Steven Knipping's Applied Houdini Rigids III Vehicle Destruction course [www.appliedhoudini.com] and I'm trying to figure out how to get my own model working in the network instead of the supplied helicopter model. I want to destroy a Spaceship that I made in C4D using a Kitbash kit, so I imagine the geometry isn't the main issue, but it certainly could be.

In this case, the main problem is that some of the pieces don't have thickness. And, instead of adding it in C4D, which is also an option, I thought it would be fun to try and do it procedurally in Houdini using the Game Tools Thicken SOP since the Poly Extrude SOP wasn't really working for me. Anyhow, if I add the thickness using separate loops before the Voronoi Fracture process it seems to work fine.

However, some of the pieces that need thickness don't need to be fractured, so I decided to add it to them at the beginning of the network the same way Steven isolated the tanks on the helicopter for the art directed cuts. For whatever reason, this seems to crash Houdini and it's starting to get annoying. It doesn't happen immediately or super often, but it's happening enough that it's slowing down work and I'm worried about it creating a problem that might end up causing me trouble down the line.

I'm on a pretty hefty Windows tower, using Houdini Indie, and I just upgraded to the latest Production Build, 18.0.499, to troubleshoot the issue but it's still happening. If anyone has the ability to look at the .hiplc file that would be a big help. I'm attaching the scene file, the latest crash file and the crash log. And, here's a Dropbox link to the model [www.dropbox.com], since it's too big to attach.

Thanks a lot,

Hi,

So I was having some issues as well with the 18.0.499 build in the DOP net. I was crashing a lot when running sims for things that I had no issue running in 18.0.287. I haven't fiddle with it to see the specific issue because I was on time constraint to get something done so I went back to 287. The crash happened with an RBD sim as well.

Submit the issue and any info you have as a problem report to SideFX.

If you have to render in 499, just cache everything (which obi youre already doing) and open that in a 499 file but sim in 287.

Thanks for the reply Hope! I don't think it was a version issue as the same thing was happening with previous versions. I eventually got it to work by playing with the order of operations where I was adding the Thicken SOP and I think I fixed it. If you've done that course and you're curious, I can upload new files for you. Just let me know.
