I'm running into some issues reading ptex files and I'm not entirely sure how to solve them.
It seems that whenever an image tile should be a constant color the very first pixel will take on that color value, but the remainder of the tile will be filled with garbage data. I've put an example of this here: https://drive.google.com/open?id=1z4N3xru0_TPRxVRDoCaQ7ODAUliJRfjM In addition, after looking over the ptex format specification ( http://ptex.us/PtexFile.html) it seems that there's a lot of information that is inaccessible through oiio. In this case I'm specifically interested in the 'adjfaces' face info but there's quite a lot of additional information that could be useful in a variety of situations. I'm using the python bindings for OpenImageIO 2.0.7. Thanks for any insight, Darby
