Hi everyone, I think this is a common question but I flipped through the forums and found no direct answer. I exported a geometry to .obj in H8 a long time ago. Since H9 has a new GUI I was wondering how it's done in H9.

Thanks

Use a ROP output driver , listed under managers and of course use the files extension .obj

Got it thanks. Does this export normals or texture coordinates or material info? or does it require further operations?

Perhaps shortcut for exporting *.obj under RMB of any SOP is still valid…?

No martial info I'm afraid. UV and N if they exists on geometry.
(UV as vertex attribute and UV as point attribute are interpreted slightly differently as I suspect but I've never investigated what is precise distinction.
Nevertheless OBJ supports two ways of defining UV and this is somehow related issue. Maybe some one can write something more.)


cheers,

I put in a simple uv project -> uv quick shade and exported again and am happy to see textures work fine in the export process. However, the normals are still not being exported. I believe they should be. I'll fiddle around with it some more.
Thanks for the help so far!

Add a Point SOP and “Add Normals” to get the normal attribute to be calculated (else it just uses the implicit face normal dictated by the vertex order).

where/how in the rop output driver does one specify the .obj file format?

Like with all filenames, it recognizes the extension.

How do I find a list of supported file types in houdini? I was unaware that I could just type in a file type and that houdini would simply do the work.

Here is an unofficial list:

http://odforce.net/wiki/index.php/FileFormats [odforce.net]

And you can also type “iconvert” on the command line for a complete list of image formats.

The help docs have the information too.
