If you have some 3d models in .obj format but for some reason Houdini is having a hard time reading them in, here is a #QuickTip that may help you out. In the past, converting the troublesome file to another format that Houdini can import has resolved the issue for me. We don’t want to convert our .obj files to just any old format. Specifically, we want to convert obj models to bgeo format.
Convert OBJ Models to BGEO format in Houdini
The .bgeo file format is the standard format for storing Houdini geometry. However, how do you convert an .obj file to .bgeo? Houdini provides a nice set of stand alone command line tools right out of the box and one of those tools is called
gwavefront. This assumes your Houdini environment is initialized.
Open up a shell and just type in gwavefront followed by the .obj file you want to convert and immediately the name of the name file with the .bgeo extension. Your milage may vary on this but from my past experience, a lot of times the conversion helps Houdini import the model.
