Hi @epth I was able to run your effect:

A possible difference is that I am using Houdini 17.5.258, also it should adapt to the version available. The Blender branch outputs a lot of debug information in the terminal, so to help me troubleshot your use case, you can run Blender from a cmd terminal and once it crashed copy the whole log it contains (select all by clicking, then mouse right click actually copies selection to clipboard).

I've tested twice,same error,same address

Hi, first of all thanks for putting the effort into this. A standardized system for procedural geometry and being able to play HDAs in Blender is a great idea.

I am have the same issue with blender crashing. I tried with all the versions of Blender built with OpenMeshEffect. I am using Houdini 18.0.566

I attached my own log in case it is helpful

Hi @wenglash, Could you share your HDA, or at least export as an OBJ one expected result? It crashes when loading geometry back as a Blender Mesh so it may come from some unhandled case in the mesh, maybe try adding some cleanup at the end of the mesh effect in Houdini.

Hi, thanks for getting back to me so fast. I've attached my HDA, it is just a simple test with subdivide and polyextrude.

What kind of cleanup would I add in Houdini?
