Re: Creating mipmapped textures with OpenImageIO
Larry Gritz <l...@...>
There is an oiio-dev group: http://lists.openimageio.org/listinfo.cgi/oiio-dev-openimageio.org
The oiiotool command line you use is writing a tiled file, but there's more to a MIP-map. When you use maketx, it's creating a multi-resolution (MIP-map levels) as well as embedding some other assorted things in the metadata that help at render time.
Somewhere on my list is to add a feature to oiiotool that would cause it to do exactly the same thing that maketx does. But at present, you're expected to use maketx for that final MIPmap creation step.
