wandersonp Posted November 17, 2011 Share Posted November 17, 2011 Hi guys, I'm starting to study houdini a few weeks and, I have this basic question. why bgeo files is better than obj or other files to import geometry? what additional information are included? Thanks Wanderson Quote Link to comment Share on other sites More sharing options...
hopbin9 Posted November 17, 2011 Share Posted November 17, 2011 BGEO files contain the native attributes that Houdini uses, and also retains Group information. Quote Link to comment Share on other sites More sharing options...
sam.h Posted November 17, 2011 Share Posted November 17, 2011 Also BEGO is much much faster than obj. Quote Link to comment Share on other sites More sharing options...

dangerweenie Posted November 17, 2011 Share Posted November 17, 2011 bgeo (and bgeoz, the compressed version) are better formats for houdini, because they are native to houdini. OBJ is slower to load, however you can load an OBJ sequence with Maya, Softimage, MAX, etc. FBX is Autodesk's format, it's ok but for what I do I think it's a pain in the ass and buggy. (Houdini->Maya). ALEMBIC is the open-source version, made for transferring point caches and materials between major 3D packages. It's only partially implemented in Houdini at the moment (there is an Alembic import SOP, with an export SOP pending (hopefully Q2 2012) ... apparently SideFX is waiting for Python Bindings .. not entirely sure what that means)). Then there's COLLADA, don't know much about that. Basically, stick with bgeo for when youre just caching stuff out in Houdini - but you're probably going to want to use OBJ or FBX if you want to bring it into Maya or something else, ie to render. The bgeo plugin for Maya (www.houdinistuff.com) is also great, though it seems to crap our ~ 64k polygons. Good Luck, odforce.net is the best place to learn Houdini - some really generous and helpful people hanging out here.

edward Posted November 17, 2011 Share Posted November 17, 2011 .bgeo files maintain full information for all the geometry that Houdini supports. For example, if you had volume primitives, this cannot be saved out to any other format.(not sure about Alembic though) Quote Link to comment Share on other sites More sharing options...

klawchi Posted November 30, 2021 Share Posted November 30, 2021 Hi guys, After 10 years is it the same case here? What about .geo? Which one is best if you want to include it to use with USD/Solaris? Thx Quote Link to comment Share on other sites More sharing options...
