Adrian Posted January 6, 2013 Share Posted January 6, 2013 I'm having issues rendering the object below. Starting in the 40-50K points ballpark, i get a memory allocation error when starting a render with Mantra. As you can see, this object is very light weight, so i can't see this being limited by mesh density this early on. Here a few tests: file node with bgeo source: mem error when reaching certain point count (see above) file node appended by convert-SOP of type nurbs curve: mem error (same threshold) rendering geometry node as points only: works, in the millions even. file node appended by polywire-SOP: works! way denser mesh! Polywire is neat, but extremely slow and i'd actually rather render curves with a constant shader so as not to consume too much memory. Any ideas what could cause this?

anim Posted January 6, 2013 Share Posted January 6, 2013 can this be related? from journal: Thursday, January 3, 2013 Houdini 12.1.180: Fixed a bug that would cause mantra to crash when rendering curves with more than 32767 points. 1 Quote Link to comment Share on other sites More sharing options...
Adrian Posted January 7, 2013 Author Share Posted January 7, 2013 (edited) Smart man! That could well be it. Someone at SESI took a short for an int, eh? Edit: I think you were right on the money. I just tested 32000 vs 33000 and that's where the crash happens. I also rendered a few duplicates at 32k without a crash. Houdini 12.1.125.
