Hi, Yes the .osg file Reader does support both representations of filename or embedded source text, so it does just become an issue of conveying the preference to the Writer. That raises several issues tho
Should ReaderWriter should somehow preserve the representation between reading and possible future rewriting, or should it always expect an explicit option? What filename should be stored in the written .osg file (the source filename is not preserved in the osg::Shader)? Should the shader source files themselves also be rewritten (perhaps the shader was modified)? Etc etc I agree it would be nice to expose the option to use a filename reference; due to all the issues, I just defaulted to the safest path. Currently when I want a filename reference, I manually edit the .osg file; not a good answer, but it works. cheers -- mew > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:osg-users- > [EMAIL PROTECTED] On Behalf Of Art Tevs > Sent: Wednesday, January 23, 2008 10:31 AM > To: OpenSceneGraph Users > Subject: [osg-users] Texture/Shader inlined output to .osg files > > Hello, > > If one writes a texture to the .osg file, then the > texture is not inlined, but it's file path is written > to the .osg file. > > I am wonder why the same doesn't happen to shader > programs.
