I need to use ETC1 compression for Android but I'm struggling to find a tool that will create image files that OSG can consume. AFAIK from searching the code, osgPlugin pvr is the only thing that will load an ETC1 compressed image. So I have the same question as Tom: is there another tool I should be using that will make ETC1 compressed pvr's with the right header?

Re: [osg-users] ETC1 Compressed textures
Answering my own question here -- Looks like my best bet would be the relatively new ktx plugin -- seems like all the etc1 compression tools out there output to this format and it's khronos-blessed as well. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=54684#54684 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] ETC1 Compressed textures

Re: [osg-users] ETC1 Compressed textures
Bit more info, I also used the 'Fast Perceptual' encoding method, if that is of any relevance. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=49308#49308 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
